Introduction to Mathmech

Updated on August 18th, 2025

Introduction

Mathmech is an archetype that focuses on swarming the field with Level 4 Cyberse Monsters, themed around mathematical and geometrical terminology (but no worries, very little counting Is involved!) Uniquely, many Mathmech cards can temporarily manipulate Monster ATKs. Although known for its OTK potential with Loading... at the start of its lifespan, the deck developed into a fairly linear Link-themed deck that prefers to go first most of the time and aims to set up an end board with varied disruptions and easily OTK on follow-up turns.

UPDATE: July 2025

It's been a while, hasn't it? Over the last year, Mathmech (and Cyberse in general) has received some hits and revisions on the banlist. Specifically, Loading... got semi-limited, Loading... also server time in the banlist at 2 copies (hit that has been lifted as of February 2025) and Loading... was limited to 1 (hit that has been reverted in the July 4th banlist). While all of this was happening however, we also got some new tools! Loading... is an extender that can return a card your opponent controls to the hand. On the other hand, Loading... is a Loading... target that can place a face-up Monster your opponent controls in the Spell & Trap Zone. This bypasses most floating effects!
Nevertheless, the overall playstyle of Mathmech remains the same. In this update, I will also highlight a different variant that utilizes Loading... . Furthermore, I will include some tips on how to play around Loading... and Loading... , two powerful handtraps that were released over the course of the game's lifespan.

Mathmech Main Deck Monsters

Mathmech Circular

Loading... , Spell/Trap searcher, 1 card starter - this incredible card does it all! The first effect allows you to send 1 Mathmech Monster from your Deck to the GY (as cost!) to Special Summon this card from your hand. However, you can only attack with 1 Monster for the rest of this turn, which is usually not a problem for Mathmech. In addition, the second effect allows you to add 1 Mathmech Spell/Trap from your Deck to your hand if you Normal or Special Summon another Mathmech Monster while you control this card. 3 Loading... are mandatory.

This card synergizes extremely well with Loading... . You can send Loading... to the GY and Special Summon Loading... . Then, you can Special Summon Loading... from the GY and add 1 Mathmech Spell/Trap, usually Loading... or Loading... . Thus, this card allows you to Special Summon 2 Monsters and search 1 Spell/Trap - all without your Normal Summon!

Mathmech Sigma

This card is an extender that can Special Summon itself from your hand or GY if you control no Monsters in the Extra Monster Zone. However, it locks you into Cyberse Extra Deck Monsters for the rest of the turn, and it is banished when it leaves the field. Note that if this card is used as an Xyz material, it is not banished when detached. Finally, while this card is on the field, it can be treated as either a Tuner or non-Tuner when used as a Synchro material for a Mathmech Monster. 1 Loading... is recommended.

Mathmech Addition

This card is another extender that can Special Summon itself from your hand by targeting a face-up Monster on the field, increasing the targeted Monster's ATK by 1000 for one turn. Like Loading... , this card locks you into Cyberse Extra Deck Monsters for the rest of the turn. 1 Loading... is recommended.

Mathmech Subtraction

This card is another extender that can Special Summon itself from your hand by targeting a face-up Monster on the field, decreasing the targeted Monster's ATK by 1000 for one turn. Like Loading... , this card locks you into Cyberse Extra Deck Monsters for the rest of the turn. Note that Loading... (and Loading... ) Special Summons itself before modulating the targeted Monster's ATK. Thus, even if the targeted Monster's ATK does not change (e.g. the targeted Monster is unaffected by card effects or is removed from the field), this card will still be Special Summoned. 1 Loading... is recommended.

Mathmech Diameter

When Normal Summoned, this card allows you to Special Summon a Level 4 Cyberse Monster in your GY (but it cannot activate its effects). Notably, all Mathmech Monsters are Level 4 Cyberse Monsters. You can also Special Summon non-Mathmech Level 4 Cyberse Monsters, such as Loading... .

In addition, a Mathmech Monster that was Synchro or Xyz Summoned using Loading... as a material gains an omni-negate during the turn it was Summoned. One of Mathmech's main gameplan is to activate Loading... to Special Summon Loading... (and 2 other Mathmech Monsters) from the GY and Xyz Summon Loading... , thus granting Loading... an omni-negate during your opponent's turn. This card is a Tuner. At least 1 Loading... is mandatory.

Mathmech Multiplication

This card allows you to increase the Level of a Level 4 Cyberse Monster to 8. Thus, you can easily Summon Loading... using Loading... and any Level 4 Tuner. Furthermore, if this card was sent to the GY, you can double the ATK of a Cyberse Monster in the Extra Monster Zone for 1 turn, allowing you to easily OTK. 1 Loading... is recommended.

Mathmech Nabla

This card allows you to tribute 1 Cyberse Monster in order to Special Summon 1 Mathmech Monster from your Deck. This can help you set up 3 Mathmech Monsters in the GY for Loading... in certain scenarios, such as the 1 card Loading... combo or the 1 card Loading... combo.

Moreover, if this card was sent to the GY, it allows a Cyberse Monster in the Extra Monster Zone to make up to 2 attacks on Monsters for 1 turn. This card is a Tuner. While the card has potential uses, mostly highlighted for decks that only run Mathmech as a small engine and the occasional Final Sigma OTK, which has far been surpassed by Terahertz already. This card Is optional at best.

Mathmech Division

This card allows you to tribute a Cyberse Monster in the Extra Monster Zone and Special Summon a Level 4 Cyberse Monster from your hand and/or GY. In addition, if it was sent to the GY, you can halve a Monster's ATK for 1 turn. However, Loading... is usually a better alternative. Thus, this card is generally not run.

Mathmech Spells/Traps

Mathmech Superfactorial

This card, combined with Loading... , is your main form of disruption. Similar to Loading... , this card allows you to Special Summon a Mathmech Synchro/Xyz Monster using Mathmech Monsters in your GY. However, unlike Loading... , this card targets and cannot use Monsters that are banished. Most commonly, you activate this card during your opponent's turn to Special Summon Loading... and non-target send to the GY up to 3 of your opponent's cards. Alternatively, you can activate this card to Special Summon Loading... using 3 Mathmech Monsters to search a Level 4 handtrap (e.g. Loading... or Loading... ). 1 Loading... is recommended, although 2 can be run if you run 2 Loading... .

Mathmech Equation

This card is an extender that can Special Summon a Mathmech Monster from your GY and increase its ATK by 1000 for one turn. 1 Loading... is mandatory.

Mathmech Induction

This card is your secondary form of disruption. If you control a Mathmech Monster, you can send this face-up card to the GY and pop 1 card your opponent controls. Note that you cannot activate this Set card and send it to the GY in the same chain. For example, if your opponent activates a continuous Spell/Trap while this card is Set, you cannot activate this Set card and destroy your opponent's card in the same chain. This card is not used for any standard builds for the deck currently and it's a more fun option at best.

Mathmech Billionblade Nayuta

This card allows you to send a Mathmech Monster from your Deck to your GY to boost the equipped Monster's ATK. This card synergizes with Loading... and Loading... , which can modulate Monster ATKs when sent to the GY. However, you can easily send Loading... and Loading... to the GY using other Mathmech cards instead. Thus, this card is generally not run.

Mathmech Extra Deck Monsters

Primathmech Alembertian

This card is your main searcher. When Summoned, it can detach 2 materials to search any Mathmech card. In addition, this card allows you to tribute 1 Monster in order to Special Summon 1 Level 4 Mathmech Monster from your hand or GY. In rarer cases, you can detach 3 materials to search any Level 4 Monster or detach 4 materials to search any Spell/Trap. 1 Loading... is mandatory, you can play another copy to guarantee better follow-up options (especially relevant with multiple copies of Diameter).

Primathmech Laplacian

This card, combined with Loading... , is your main form of disruption. When Summoned, it can non-target send to the GY up to 3 of your opponent's cards. Usually, you want to Summon it during your opponent's turn using Loading... and Loading... , which provides an omni-negate. This card also has a Continuous Effect that allows you to detach 1 material to protect Mathmech cards you control from destruction by card effects. This effect is not an Activated Effect and does not start a chain. 1 Loading... is recommended.

Geomathmech Final Sigma

This card is your in-archetype boss Monster. While in the Extra Monster Zone, it is unaffected by card effects (except Mathmech cards) and doubles any battle damage it inflicts when battling an opponent's Monster. Note that the battle damage is not doubled if it is a direct attack. In general, you want to Summon it using Loading... to double its ATK and immediately OTK. This card also searches any Mathmech card when it is destroyed by battle or card effect. However, this effect is rarely used since you should only Summon Loading... when you are certain that you can OTK. Unfortunately, Loading... and Loading... are generally better alternatives. Thus, this card is not mandatory, although it can be helpful in certain scenarios.

Geomathmech Magma

This card allows you to destroy up to 2 of your opponent's cards if it destroyed a Monster by battle. However, Loading... is generally a better alternative. Thus, this card is generally not run.

Non-Mathmech Cards

Cynet Mining

This card, along with Loading... , is your main consistency card. It allows you to search any Level 4 or lower Cyberse Monster at the cost of sending 1 card from your hand to the GY. Usually, you want to search Loading... . 3 Loading... are mandatory.

Small World

This card is another consistency card. It allows you to banish 1 Monster (A) from your hand and 1 Monster (B) from your Deck, then add 1 Monster (C) from your Deck, given that Monsters (A) and (B) share exactly 1 trait (i.e. Type, Attribute, Level, ATK, or DEF), and Monsters (B) and (C) also share exactly 1 trait. Thus, this card allows you to search combo pieces, handtraps, or even board breakers. 3 Loading... are mandatory. See the "Tips & Tricks" tab for more details.

Link Decoder

This card is a Link-1 Monster that requires 1 Level 4 or lower Cyberse Monster. You can Link Summon this card using any Mathmech Main Deck Monster. If this card is sent to the GY as Link Material for a Cyberse Link Monster with 2300+ original ATK (e.g. Loading... or Loading... ), you can Special Summon this card, but banish it when it leaves the field. This allows you to link climb into powerful Link Monsters such as Loading... . 1 Loading... is mandatory.

Splash Mage

This card is a Link-2 Monster that requires any 2 Cyberse Monsters and can be used to Link climb. It allows you to Special Summon a Cyberse Monster from your GY in Defense Position (but its effects are negated). However, you can only Special Summon Cyberse Monsters for the rest of the turn. 1 Loading... is recommended.

Transcode Talker

This card is a Link-3 Monster that requires 2+ Effect Monsters (including non-Cyberse Monsters) and can be used to Link climb. It allows you to Special Summon 1 Link-3 or lower Cyberse Link Monster from your GY to a zone this card points to. However, you cannot Special Summon non-Cyberse Monsters the turn you activate this effect. Note that this card's restriction is different from Loading... 's! Whereas Loading... 's restriction only applies for the rest of the turn after you activate its effect, Loading... 's effect applies to the entire turn you activate its effect. In other words, you cannot activate Loading... 's effect and Special Summon a non-Cyberse Monster in the same turn, regardless of whether you Special Summon the non-Cyberse Monster before or after activating Loading... 's effect. This card also provides targeting protection to both itself and its co-linked Monsters, which can be helpful against cards such as Loading... . 1 Loading... is mandatory.

Decode Talker Heatsoul

This card is a Link-3 Monster that requires 2+ Cyberse Monsters with different attributes. Every turn (including your opponent's turn), you can pay 1000 LP to draw 1 card. This allows you to draw into handtraps, extenders, etc. In addition, if your LP are 2000 or less, you can banish this card and Special Summon a Link-3 or lower Cyberse Monster from your Extra Deck, although this effect is generally not relevant to Mathmech. 1 Loading... is mandatory.

Accesscode Talker

This card is a Link-4 Monster that requires 2+ Effect Monsters (including non-Cyberse Monsters) and is your boss Monster. In general, you want to Summon Loading... over Loading... if your opponent does not control any Monsters in Attack Position OR if your opponent controls any card that needs to be popped. Combined with Loading... , this card allows you to easily OTK. 1 Loading... is mandatory.

Firewall Dragon Darkfluid - Neo Tempest Terahertz

Loading... is a high-investment end board piece with versatile applications. Most importantly, it has a Quick Effect to send 1 Cyberse Monster from your Deck or Extra Deck to the GY. Loading... is the main target for Loading... to send to the GY. Importantly, it allows you to negate a Spell/Trap card or effect. 1 Loading... and 1 Loading... are mandatory. More information about Loading... and other potential targets to send to the GY with Loading... can be found in the next tab.

Loading... also has additional effects that allow you to easily OTK:

This card has a Continuous Effect that negates any opponent's Monster effect activated during the Battle Phase. This is particularly useful for multiple scenarios, most notably it can prevent monsters to Special Summon themselves during battle to stop your attack (for example, Loading... or "Bystial" monsters) and protects you from handtraps in general, making it very hard to interact with your OTK attempt.
When this card sends a Cyberse Monster to the GY, it gains both 2500 ATK and the sent Monster's Attribute. This allows it to have a surprising synergy with Loading... . If you send an EARTH Cyberse Monster (e.g. Loading... ) to the GY, this card gains the EARTH Attribute. Then, if it is co-linked to Loading... , it can make a second attack during each Battle Phase and inflict piercing battle damage.
This card can make a number of attacks on Monsters each Battle Phase, up to the number of its Attributes.

Parallel eXceed

This card is an extender that can Special Summon itself from your hand when you Link Summon. You can then Special Summon another Loading... from your Deck. Since its Level becomes 4, you can use this card to Summon Link Monsters like Loading... or Xyz Monsters like Loading... . 2 Loading... are highly recommended.

Salamangreat Almiraj

This card is a Link-1 Monster that requires 1 Normal Summoned Monster with 1000 or less ATK. You can Link Summon this card using common handtraps such as Loading... or Loading... . Thus, when combined with Loading... , this card can unbrick suboptimal hands. 1 Loading... is highly recommended.

Linguriboh

G Golem Crystal Heart

This card is a Link-2 Monster that requires 2 Cyberse Monsters. The first effect allows you to Special Summon 1 EARTH Link Monster in your GY to your zone this card points to. This card particularly synergizes with Loading... . 1 Loading... is highly recommended.

Update Jammer

This card is a Link-2 Monster that requires 2 Level 2 or higher Cyberse Monsters. Most importantly, if this card is sent to the GY as Link material, that Link Monster can attack twice during each Battle Phase this turn. Thus, this card enables Loading... to easily OTK. With the advent of Loading... , the relevance of this card dropped but it can still be valuable to consider for more varied options going 2nd.

Link Spider

This card is a Link-1 Monster that requires 1 Normal Monster. You can Link Summon this card using Tokens generated by cards such as your opponent's Loading... .

Cyberse Wicckid

This card is a Link-2 Monster that requires any 2 Cyberse Monsters. Importantly, it allows you to search any Cyberse Tuner (e.g. Loading... ) if a Monster is Special Summoned to a zone it points to, especially useful for grabbing follow-up. In addition, this card also protects Cyberse Monsters it points to from destruction by card effects.

I:P Masquerena

This card is a Link-2 Monster that requires 2 non-Link Monsters and provides a secondary disruption. During your opponent's Main Phase, you can Link Summon a Link Monster (e.g. Loading... ) using materials you control, including this card. In addition, a Link Monster that used this card as material cannot be destroyed by your opponent's card effects.

Gatchiri @Ignister

This card is an extender that can Special Summon itself from your hand by negating the effects of 1 Cyberse Effect Monster you control. Then, if this card is sent from the field to the GY, you can make 1 face-up Monster you control unaffected by your opponent's card effects until the end of your opponent's turn. Thus, you can Link Summon Loading... or Loading... using this card to ensure an OTK.

EM:P Meowmine

This card can Special Summon itself from your hand if a Link Monster is on the field or in either GY. In addition, if a Link-2 Monster you control is sent to the GY or banished, you can banish this card from your hand or GY to return 1 card your opponent controls to the hand. This card synergizes well with Loading... .

Archfiend Eccentrick

This card is an excellent Loading... bridge. Moreover, it has a useful Pendulum Effect that allows you to destroy both this card and 1 other Spell/Trap on the field.

Loading... Targets

Depending on your Extra Deck space, you can run up to 3 Loading... targets in your Extra Deck. In general, Loading... is mandatory, and Loading... or Loading... is highly recommended.

Cyberse Desavewurm

This card is the main target for Loading... to send to the GY. You can Quick Effect banish this card from the GY to negate the activation of a Spell/Trap Card or effect. However, you must control a Link-4 or higher Cyberse Monster (e.g. Loading... ) to activate this effect. 1 Loading... is mandatory.

Mereologic Aggregator

If this card is sent to the GY, you can negate the effects of 1 face-up card on the field until the end of this turn. Note that this effect occurs in a separate chain from Loading... 's effect. This card is particularly useful against any card with Ignition effects on field (some examples can be Loading... , Loading... , Loading... just to name a few) or alternatively , you can use Terahertz's effect to send Loading... to GY in response to a card that would Special Summon another monster instead; if this occurs during opponent's turn, due to how priority works, our Loading... 's effect will be chained to any on-summon effect our opponent's monsters May have, negating it (examples could be Loading... summoning Loading... or Loading... summoning Loading... etc.). Both Loading... and Loading... are highly recommended, or at the very least 1 on them should be included always for any standard build.

Enigmaster Packbit

If this card is sent to the GY, you can discard 1 card and place 1 face-up Monster your opponent controls in the Spell & Trap Zone. Importantly, this effect does not trigger most floating effects, such as Loading... . Interestingly, you can also use this effect if you properly Synchro Summon this card, which is conveniently a Level 8 Cyberse Monster. Similarly to Loading... , Packbit's effect will work on a separate chain after being sent to the GY by Loading... and shares some of its use cases.1 Loading... or 1 Loading... is highly recommended.

Wind Pegasus @Ignister

This card has a GY effect that allows you to shuffle 1 card your opponent controls into the Deck if another card you control is destroyed by battle or card effect.

Micro Coder

This card can search 1 Cynet Spell/Trap if it is sent from the hand or field to the GY as Link Material of a Code Talker Monster. If this card sent from the field, you can search 1 Level 4 Cyberse Monster instead. Usually, you will search Loading... , which provides an omni-negate. Alternatively, you can search Loading... . You can send this card to the GY with Loading... , then Special Summon it from the GY with Loading... to link if off into Loading... to make Loading... usable (you need to control a ''Code Talker'' Link monster for its activation).

Mathmech Multiplication

If you Summon Loading... in the Extra Monster Zone and send Loading... to the GY, you can increase the former card's ATK to 11,000! This provides an alternative way to OTK. If you choose to do this, always activate Loading... 's effect during the Battle Phase. This prevents your opponent from responding with Monster effects such as Loading... .

Any Mathmech Monster

Sometimes, you are unable to set up 3 Mathmech Monsters with different names in the GY for Loading... . You can use Loading... 's effect to send any missing Mathmech Monster to the GY.

I:P Masquerena Targets

Some of the variants for the deck facilitates the usare of Loading... as a part of our endboard (in particular, Loading... and in the past for builds centered around Loading... /Loading... ) , hence we also have to run specific payoffs to access through her effect. Broadly speaking, Loading... or Loading... are the most common choices, but these are all the targets that have been used historically for the deck.

S:P Little Knight

If this card is Link Summoned (using Loading... ), you can banish 1 card on the field or in either GY. Note that after activating its first effect, you won't be able to attack directly for the rest of the turn.In addition, when your opponent activates a card or effect, this card can banish 2 face-up Monsters on the field (including a Monster you control) until the End Phase. This card can therefore provide up to 2 disruptions!

Apollousa, Bow of the Goddess

This card can negate the activation of Monster effects, up to the number of Link materials used for its Link Summon. Importantly, it can protect Loading... from cards such as Loading... , Loading... , Bystials, and Ishizu shufflers.

Knightmare Unicorn

If this card is Link Summoned, you can discard 1 card and shuffle 1 card on the field into the Deck.

Underworld Goddess of the Closed World

This card can provide multiple forms of disruption. Importantly, this card is a Kaiju that can be Link Summoned using 1 Monster your opponent controls as material. If this card is Link Summoned, you can negate the effects of all face-up Monsters your opponent currently controls. In addition, it can negate the activation of a card or effect that Special Summons a Monster(s) from the GY. Finally, this Link Summoned card is unaffected by your opponent's non-targeting activated effects.

Topologic Zeroboros

This card can help deal with backrow-heavy decks. If another Monster is Special Summoned to a zone any Link Monster points to, it will banish all cards on the field. This effect is NOT once per turn and is mandatory. Then, this card will Special Summon itself during the next Standby Phase. You can trigger this card's effect during your opponent's turn with Loading... .

Topologic Trisbaena

Like Loading... , this card can help deal with backrow-heavy decks. If another Monster is Special Summoned to a zone this card points to, it will banish as many of those Monster(s) as possible and as many Spells/Traps on the field as possible. This effect is NOT once per turn and is mandatory. However, unlike Loading... , this card does not banish itself. You can trigger this card's effect during your opponent's turn with Loading... .

Mekk-Knight Crusadia Avramax

This card is a tower that cannot be targeted by your opponent's card effects. In addition, if this card was Link Summoned using Loading... as material, it cannot be destroyed by your opponent's card effects. Thus, it is very difficult to remove from the field for many decks. In addition, this card has a floating effect that non-target shuffles 1 card on the field into the Deck.

The Arrival Cyberse @Ignister

This card is a tower that is completely unaffected by other cards' effects. It requires 3+ Monsters with different Attributes, and its original ATK becomes 1000 x the number of Link materials used for its Link Summon. Furthermore, this card can destroy 1 other Monster on the field and Special Summon 1 Token to a zone this card points to.

Topologic Bomber Dragon

This card can help deal with decks that spam Monsters on the field. If another Monster is Special Summoned to a zone any Link Monster points to, it will destroy all Monsters in the Main Monster Zone. This effect is NOT once per turn and is mandatory. You can trigger this card's effect during your opponent's turn with Loading... .

Handtraps, Board Breakers, & Other Staple Cards

Maxx "C"

This powerful handtrap can severely limit your opponent's plays, giving you draws for every Special Summon their perform. Play as many copies of Loading... are currently legal.

Ash Blossom & Joyous Spring

This versatile handtrap is useful against most decks. In addition, it can negate your opponent's Loading... . 3 Loading... are mandatory.

Ghost Belle & Haunted Mansion

This handtrap can protect your Loading... from cards such as Loading... , Loading... , Bystials, and Ishizu shufflers. This ensures that Loading... can be Summoned using Loading... , which grants an omni-negate. It can also protect other effects that Special Summon from the GY such as Loading... and Loading... . Finally, this card can be useful in certain matchups such as Branded Despia (Loading... ) and the Mathmech mirror (Loading... ). As the nature of the formats tend to shift constantly, Loading... can fall in and out of favor depending on the popular decks at the time, but it's a generically decent option for the added value it can provide for our interactions in particular.

Effect Veiler

This versatile handtrap is useful against most decks. Moreover, it is a Loading... bridge to Loading... . At least 1 Loading... is highly recommended.

Infinite Impermanence

This handtrap is similar to Loading... . However, since it is not a Monster, it cannot be used as a Loading... bridge. Furthermore, because this card can only be activated from your hand if you control no cards, it does not synergize well with Loading... .

Unlike Loading... , however, this card can be activated outside of your opponent's Main Phase. In addition, since it is not a Monster, it does not trigger your opponent's Loading... nor Loading... .

Other Handtraps

These other handtraps can be useful in certain scenarios, depending on the format.

Called by the Grave

This card can help deal with your opponent's handtraps, including Loading... . 2 Loading... are mandatory.

Crossout Designator

Similar to Loading... , this card can you deal with your opponent's handtraps. 1 Loading... is highly recommended.

Kaijus

Kaijus are board breakers that can be Special Summoned from your hand to your opponent's field by Tributing 1 Monster they control. However, because none of the Kaijus are Cyberse Monsters, you cannot activate Loading... 's effect the turn you Special Summon a Kaiju. Both Loading... and Loading... are Kaijus that can be easily searched by Loading... .

Lava Golem

Similar to Kaijus, this card is a board breaker that can be Special Summoned from your hand to your opponent's field by Tributing 2 Monsters they control. However, you cannot Normal Summon/Set the turn you Special Summon this card. Furthermore, because this card is not a Cyberse Monster, you cannot activate Loading... 's effect the turn you Special Summon this card. This card can be searched by Loading... .

Kurikara Divincarnate

This card is a board breaker that can be Special Summoned from your hand by Tributing face-up Monsters in your opponent's Monster Zone that activated their effects this turn. Then, during your End Phase, you can Special Summon 1 Monster in your opponent's GY, although this effect is less relevant in Mathmech. Because this card is not a Cyberse Monster, you cannot activate Loading... 's effect the turn you Special Summon this card. This card can be searched by Loading... .

Backrow Removal

These cards can help you deal with backrow-heavy decks.

Cons:

Loading... competes for your Normal Summon
Loading... prevents you from Special Summoning non-Cyberse Monsters for the entire turn
Requires 1 Main Deck garnet

Conflict Engine

Loading... is a powerful Counter Trap that provides an omni-negate if you control a Code Talker Monster (e.g. Loading... ). You can search this card with Loading... if the latter was sent from the hand or field to the GY as material for the Link Summon of a Code Talker Monster. You can send this card to the GY with Loading... , then Special Summon it from the GY with Loading... . 1 Loading... and 1 Loading... are mandatory.

Singularity Engine

This card is a Link-6 Monster that requires 3+ Effect Monsters. It is a high-investment end board piece that allows you to bounce cards from your opponent's field or GY. The number of cards that you can bounce depends on the number of different types of Monsters (Ritual, Fusion, Synchro, or Xyz) you control and in your GY. At minimum, you should have an Xyz Monster (i.e. Loading... ) in your GY. In addition, if a Monster(s) this card points to is destroyed by battle or sent to the GY, you can Special Summon 1 Cyberse Monster in your GY. This allows you to extend during your turn and Link climb into Loading... . 1 Loading... is mandatory.

V-LAN Engine

This card is a Link-3 Monster that requires 2+ Monsters (except Tokens). It can tribute 1 Link-3 or lower Monster co-linked to this card to Special Summon V-LAN Tokens equal to the tributed Monster's Link Rating. Note that you cannot Special Summon Monsters with the same Link Rating as the tributed Monster for the rest of this turn. Usually, you will tribute Loading... to Special Summon 3 V-LAN Tokens. Then, you can use these Tokens to Link Summon Monsters such as Loading... or Loading... . In general, you can supplement Loading... with one of two packages: Loading... or Loading... .

Protectcode Talker

Loading... protects Link-4 or higher Monsters (e.g. Loading... ) that you control from being targeted by your opponent's card effects or destroyed by battle. In addition, you can banish Link Monsters from your GY whose combined Link Ratings is exactly 3 to Special Summon this card from your GY. For example, you can banish Loading... and Loading... from your GY. Therefore, this card can either protect your end board or allow you to Link climb into additional end board pieces.

I:P Masquerena

You can Link Summon Loading... using 2 V-LAN Tokens. Then, during your opponent's Main Phase, you can Link Summon Loading... using Loading... and 1 Effect Monster, such as Loading... (from Loading... ). When Loading... is Link Summoned, you can banish 1 card on the field or in either GY. Furthermore, when your opponent activates a card or effect, you can banish 2 face-up Monsters on the field (including 1 Monster you control) until the End Phase. Thus, Loading... can provide up to 2 disruptions!

Spirit Engine

Number 41: Bagooska the Terribly Tired Tapir

The Spirit engine provides Level 4 extenders that allow you to easily Summon Loading... . Loading... can reveal itself in your hand, then Normal Summon 1 Spirit Monster from your hand. This effect does not consume your Normal Summon. In addition, since it does not Special Summon, this effect does not conflict with summoning restrictions on cards such as Loading... . If you tribute this card with Loading... , you can add 1 Spirit Monster from your GY to your hand, which can then be used for Loading... /Loading... or for follow-up.

Activate Loading... 's effect to send 1 EARTH Cyberse Monster from your Deck or Extra Deck to the GY. EARTH Cyberse Monsters include Loading... , Loading... , Loading... , etc. This increases Loading... 's ATK to 6100. In addition, Loading... can attack twice during the Battle Phase and deal piercing battle damage!

Rulings on Loading...

If Loading... 's effect is negated (e.g. by Loading... or Loading... ), it will still give an omni-negate to an Xyz or Synchro Mathmech Monster that was Summoned using this card.
Similarly, if your opponent used Loading... to banish Loading... from your GY, and you Summon an Xyz or Synchro Mathmech Monster with another copy of Loading... , it will still give an omni-negate.
The omni-negate given by Loading... must be applied to the first Xyz or Synchro Mathmech Monster that was Summoned using this card and cannot be applied to more than one Mathmech Monster.
Since Diameter's negate is an effect negation, it cannot be activated during during Damage Step per game rules.
The negate only stops activated effects, so it won't work against cards such as Loading... or Loading...

Rulings on Loading... + Loading...

You must chain link 1 Loading... 's effect and chain link 2 Loading... 's effect. This way, your Loading... 's ATK becomes 2300 → 5300 → 10600. In addition, your opponent cannot respond to this. On the other hand, if you chain link 1 Loading... 's effect and chain link 2 Loading... 's effect, your Loading... 's ATK becomes 2300 → 4600 → 7600. Furthermore, your opponent can respond to this.
If your opponent negates Loading... 's effect (e.g. by Loading... ), its ATK will remain at 10600, not 2300.
If you do not successfully OTK, Loading... 's ATK will return to 2300, not 5300, at the end of your turn.

Additional rulings/niche interactions to consider

If you activate the effect of Mathmech Sigma, even if it does not successfully summon on resolution (such as being banished by bystials), the restriction still applies as long as its effect or activation is not negated. The same applies to Mathmech Circular, Mathmech Addition, Mathmech Subtraction, Splash Mage, and Transcode Talker.
Under Macro Cosmos, you cannot activate the effect of Cynet Mining or Mathmech Circular in hand as they require cards to be sent to the graveyard as cost. Although you are allowed to activate Terahertz's effect, on resolution you would be forced to banish a Cyberse monster from your Deck/Extra deck, and will not gain either the attack boost or the attribute.
Transcode Talker's effect requires the monster to be special summoned to its own linked zone. As such, if it is no longer on the field during the resolution, you do not special summon that monster (but the lock still applies). This also applies to G-Golem Crystal Heart. Similarly, if the link monster for the purpose of Parallel Exceed is no longer on the field during the resolution, it will not be special summoned.
If the link summon of a monster is negated, the link materials will not be treated as being sent to the graveyard as material for a Link Monster. In this case, the effect of Firewall Defense, Firewall Guardian, Link Decoder and Micro Coder cannot be activated.
When trying to resolve Laplacian's effects, always be mindful of how chain links and turn priority will affect you! Once Superfactorial resolves and you've summoned Laplacian succesfully, effect window pops up asking you to activate Laplacian's on-summon effect to detatch and send cards to GY (if there are other trigger effects activating at the same time and they decide to activate them, priority will be given to the turn player) - if you intend on using the negate effect provided by Diameter to respond to an opponent's effect that has priority over yours on Laplacian's summon, you'll have to "skip" the on-summon effect to send cards to have the option to negate; for example, let's assume your opponent has activated Loading... and you want to be able to stop the effect of the monster which they choose to summon, chains would resolve as follows: Opponent activates Branded Fusion, you chain Mathmech Superfactorial - chain resolves backwards so Laplacian gets summoned to the field and then the opponent summons Loading... Afterwards, since it's the opponent's turn, their trigger effect will take priority and they activate Lubellion's effect as Chain Link 1 - now priority will go to us and the trigger effect that Laplacian has on-summon can be activated, but since we want to use Diameter's negate in response to Lubellion, we won't be able to use the on-summon effect since the negate needs to be directly chained to the card it is trying to deny.
Loading... 's effect not only negate the effect activation of a trap card, but also banish it. If cards cannot be banished (for example, under the influence of Loading... or Loading... ), you cannot activate the effect of Linguriboh under any circumstances. The same applies to Loading... . This fundamentally functions differently from "negate the activation, if you do, destroy it", which can be activated even if the cards affected cannot be destroyed by card effects.
Loading... negates the activation of a Spell/Trap card or effect, implying that it can be activated during the damage step. Also, if it negates the card activation of a continuous Spell/Trap card, that card will be sent to GY after the whole chain resolves. (That card will not be treated as being sent to GY by card effect, nor is it being sent from the field to GY)
The Quick Effect of Loading... can be activated during the damage step (up to Before Damage Calculation). It can be useful against cards such as Loading... .
If the effect of Terahertz is negated, the attack boost and the extra attributes will be removed and the same applies to Loading... ; however, if their ATK stats have been modified by a different card (notably, Loading... ) it will stay as the newly set value until the duration of the effect.
Surprisingly, Update Jammer's Quick Effect is not treated as an activated effect in Master Duel. Against monsters unaffected by activated effect (such as a Light-material Chaos Angel), you can use Update Jammer's effect to negate it during damage calculation. In the case of Psychic End Punisher, it's effect will be negated and it's attack will return to its original value even after Update Jammer's effect no longer applies.

How to Play Around Loading...

Loading... is an incredibly powerful handtrap that can severely limit your plays if it successfully resolves. However, you can still set up a modest end board that gives your opponent a minimal number of draws.
Suppose that you opened Loading... + Loading... . You can set up Loading... in 2 draws.
1. If your opponent activates Loading... during your Draw Phase: Activate Loading... 's effect to Special Summon itself from your hand by sending Loading... from your Deck to the GY.
2. Sometimes, your opponent will activate Loading... in response to Loading... 's effect. Since Loading... sends a Mathmech Monster as cost, you will usually send Loading... instead of Loading... in this case. You can still set up Loading... in 2 draws, but you will not be able to set up the omni-negate provided by Loading... .
3. Normal Summon Loading... .
4. Activate Loading... 's effect to search Loading... .
5. Xyz Summon Loading... using Loading... and Loading... .
6. Activate Loading... 's effect to search any Mathmech card for follow-up.

How to Play Around Loading...

Loading... allows your opponent to draw 1 card each time you Normal or Special Summon from the hand.
The standard 1 card Loading... combo only gives 2 draws:
1. Loading... (Special Summon from hand)
2. Loading... (Normal Summon from hand)
Most extenders, such as Loading... , Loading... , Loading... , and Loading... (first effect only), gives an additional draw.
Usually, it is worth going for the 1 card Loading... combo. If your 1-card combo is disrupted, it may be worth using 1 extender to complete the combo and set up Loading... and/or Loading... .

How to Play Around Loading...

Loading... allows your opponent to draw 1 card each time you Special Summon from the Deck or Extra Deck.
Given that Mathmech likes to Special Summon from the Extra Deck, this is a bit more tricky to play around than Loading... .
However, you can still set up a modest end board that gives your opponent a minimal number of draws.
Suppose that you opened Loading... . You can set up Loading... and Loading... in 2 draws.
1. Activate Loading... 's effect to Special Summon itself from your hand by sending Loading... from your Deck to the GY.
2. Activate Loading... 's effect to Special Summon itself from the GY.
3. Activate Loading... 's effect to search Loading... .
4. Xyz Summon Loading... using Loading... and Loading... . Your opponent draws 1 card.
5. Activate Loading... 's effect to search Loading... .
6. Normal Summon Loading... .
7. Activate Loading... 's effect to Special Summon Loading... from the GY.
8. Link Summon Loading... using Loading... and Loading... . Your opponent draws 1 card.
Alternatively, suppose that you opened Loading... . You can set up Loading... and Loading... in 3 draws.
1. Activate Loading... 's effect to Special Summon itself from your hand by sending Loading... from your Deck to the GY.
2. Activate Loading... 's effect to Special Summon itself from the GY.
3. Activate Loading... 's effect to search Loading... .
4. Xyz Summon Loading... using Loading... and Loading... . Your opponent draws 1 card.
5. Activate Loading... 's effect to search Loading... .
6. Normal Summon Loading... .
7. Activate Loading... 's effect to Special Summon Loading... from the GY.
8. Link Summon Loading... using Loading... . Your opponent draws 1 card.
9. Link Summon Loading... using Loading... , Loading... , and Loading... . Your opponent draws 1 card.

How to Play Around Loading...

Loading... is a meta-dependent handtrap that is particularly effective against Decks that like to search multiple cards.
In Mathmech, there are usually 2 important cards that search, namely Loading... and Loading... . The key to playing around Loading... is to activate both Loading... and Loading... 's effects in the same chain. Your opponent can then activate Loading... afterward, but you have already performed your important searches.
Suppose that you opened Loading... + Loading... .
1. Activate Loading... 's effect to Special Summon itself from your hand by sending Loading... from your Deck to the GY.
2. Activate Loading... 's effect to Special Summon itself from the GY. Do not activate Loading... 's effect here.
3. Activate Loading... 's effect to Special Summon itself from your hand. Do not activate Loading... 's effect here.
4. Xyz Summon Loading... using Loading... and Loading... .
5. On chain link 1, activate Loading... 's effect to search Loading... .
6. On chain link 2, activate Loading... 's effect to search Loading... .

Restrictions to Keep in Mind

Keep in mind the various restrictions of your cards! These restrictions can have minor differences from each other, such as whether they apply to the entire turn or to only the rest of the turn.
Loading... , Loading... , and Loading... lock you into Cyberse Extra Deck Monsters for the rest of the turn.
Loading... locks you into Cyberse Monsters (both Main Deck and Extra Deck) for the rest of the turn.
Loading... locks you into Cyberse Monsters (both Main Deck and Extra Deck) for the entire turn, both before and after you activated its effect. For example, if you Special Summoned a Kaiju Monster, you cannot activate this card's effect.
Loading... also locks you into Cyberse Monsters (both Main Deck and Extra Deck) for the entire turn, both before and after you activated its effect. For example, if you Special Summoned a Kaiju Monster, you cannot activate this card's effect.
Loading... allows you to only attack with 1 Monster for the rest of the turn.
You can only activate Loading... 's GY effect if you control a Link-4 or higher Cyberse Monster, usually Loading... .

Deck Building Tips

Mathmech cards can be found in the Singular Strike Overthrow secret pack. You need, at minimum, 3 Loading... and 1 Loading... . Sky Striker cards can also be found in this secret pack!
Loading... and Loading... can be found in the Burning Spirits structure deck. You need, at minimum, 2 Loading... and 1 Loading... . Salamangreat cards can also be found in this structure deck. You only need to buy 2 copies of the structure deck.
Most handtraps can only be found in the Master Pack. Thus, I recommend that you craft these cards instead.

How to Use Loading...

First, banish face-down 1 Monster (A) from your hand and 1 Monster (B) from your Deck, where Monsters (A) and (B) share exactly 1 trait (i.e. Type, Attribute, Level, ATK, or DEF). Then, add from the Deck to your hand 1 Monster (C), where Monsters (B) and (C) also share exactly 1 trait (i.e. Type, Attribute, Level, ATK, or DEF).
For example, suppose that you have Loading... in your hand. You can reveal Loading... , which shares exactly 1 trait with Loading... (ATK: 0). Then, you can add Loading... , which shares exactly 1 trait with Loading... (Attribute: LIGHT).
In general, your main search target for Loading... is Loading... . If you already have Loading... in your hand, you can activate Loading... at the start of your Main Phase to search Loading... (to negate your opponent's Loading... ). If you have Loading... at the end of your turn, you can search Loading... (to protect your Loading... ).
Keep in mind that all Mathmech Monsters are Level 4 Cyberse Monsters. Thus, any 2 Mathmech Monsters share at least 2 traits and cannot bridge directly with each other. Non-Level 4 Cyberse Monsters, such as Loading... and Loading... , can bridge between most (but not necessarily all) Mathmech Monsters.

- What does a typical end board look like?

Mathmech is a linear combo deck that wants to go first, set up an end board with varied disruptions on turn 1, and OTK on turn 3. In general, you want to end turn 1 with at least 3 Mathmech Monsters (ideally including Loading... ) in your GY. Then, you can Summon Loading... during your opponent's turn with Loading... . On turn 3, try to OTK with Loading... , Loading... , or Loading... .

Which variant should I run?

While the main goal generally remains the same, different versions of decklists will supplement that goal with specific payoffs: aside from meta relevance, we advise players to take into consideration their personal preferences as well for what these options provide. In order to facilitate the choice of which version to go for, we have illustrated some pros and cons for each of these, which hopefully will prove useful for whoever reads this!

Why doesn't the game let me chain link 1 Loading... 's effect and chain link 2 Loading... 's effect?

In order to manually select the order of activation when multiple cards can be activated simultaneously, you must go into Game Settings > Duel > Activation Order Settings and change it from Off (default) to On.

Why doesn't the game let me activate Loading... 's effect?

Loading... has a restriction that prevents you from Special Summoning non-Cyberse Monsters. This applies to the entire turn. For example, if you Special Summoned a Kaiju Monster, you cannot activate Loading... 's effect in the same turn.

Where is Loading... ?

Previously, Loading... was often run as both a starter and an extender in Mathmech. However, this card is no longer necessary after the release of Loading... .

Can I include a Mathmech engine in other decks?

Yes! A Mathmech engine can now be included in many decks, particularly Cyberse or Rank 4 decks (e.g. @Ignister). Typically, you have two options. The first option allows you to Summon several Cyberse Monsters without your Normal Summon:

The second option allows you to set up Loading... with 3 Mathmech Monsters in your GY:
