Introduction
Mathmech is an archetype that focuses on swarming the field with Level 4 Cyberse Monsters in order to Summon Synchro, Xyz, and/or Link Monsters. Uniquely, many Mathmech cards can temporarily manipulate Monster ATKs. Although known for its going second potential to OTK with Geomathmech Final Sigma, this deck is flexible and prefers to go first most of the time. Going first, this deck aims to set up a modest end board with decent interruptions and perform an OTK on the following turn.

Mathmech Cards
Mathmech Diameter

When Normal Summoned, this card allows you to Special Summon a Level 4 Cyberse Monster in your GY. 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. This card is also a Tuner. 3 Loading... are mandatory.
Mathmech Nabla
This card allows you to tribute 1 Cyberse Monster in order to Special Summon 1 Mathmech Monster from your Deck. Furthermore, during the turn Mathmech Nabla was sent to the GY, your Cyberse Monster in the Extra Monster Zone can make up to 2 attacks on Monsters. This card is also a Tuner. 1 Mathmech Nabla is mandatory, although 2 are recommended if you run Loading....
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, this card can be treated as either a Tuner or non-Tuner when used as a Synchro material for a Mathmech Monster. 3 Mathmech Sigma are mandatory.
Mathmech Addition/Subtraction
These cards are extenders that can Special Summon themselves from your hand by targeting a face-up Monster on the field, increasing/decreasing the targeted Monster's ATK by 1000 for one turn. Like Mathmech Sigma, they lock you into Cyberse Extra Deck Monsters for the rest of the turn. These cards are non-Tuners. 3 Mathmech Addition and 3 Mathmech Subtraction are mandatory.
Mathmech Multiplication
This card can increase the Level of a Level 4 Cyberse Monster to 8. Thus, you can easily Summon Geomathmech Final Sigma using Mathmech Multiplication and any Level 4 Tuner. Furthermore, during the turn Mathmech Multiplication was sent to the GY, you can double the ATK of a Cyberse Monster in the Extra Monster Zone, allowing you to easily OTK. This card is a non-Tuner. 1 Mathmech Multiplication is mandatory.
Mathmech Superfactorial
Similar to Loading..., this card allows you to Special Summon a Mathmech Synchro/Xyz Monster using Mathmech Monsters in your GY. Most commonly, you activate this card during your opponent's turn to Special Summon Primathmech Laplacian. 1 Mathmech Superfactorial is mandatory, although 2 are recommended if you run Loading... and/or 2 Primathmech Laplacian.
Primathmech Alembertian

This card is your main searcher. When Summoned, it can search any Mathmech card, most commonly Mathmech Superfactorial. 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. 2 Loading... are mandatory.
Primathmech Laplacian
This card 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 Mathmech Superfactorial and Loading..., which provides an omni-negate. This card can also protect your Mathmech cards from destruction by card effects. 1 Primathmech Laplacian is mandatory.
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 Mathmech Multiplication 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 Geomathmech Final Sigma when you are certain that you can OTK. 1 Geomathmech Final Sigma is mandatory.
Other Mathmech Cards
The remaining Mathmech cards are useful in certain situations, but are generally not run in most Mathmech decks.
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, during the turn it was sent to the GY, it can halve a Monster's ATK. However, Mathmech Multiplication is generally a better alternative.
Mathmech Equation
This card is an extender that can Special Summon a Mathmech Monster from your GY. However, unlike most of your other extenders, it does not add an additional Mathmech Monster name to your GY and thus does not set up Mathmech Superfactorial.
Mathmech Billionblade Nayuta

This card is an equip card that allows you to send a Mathmech Monster from your Deck to your GY to boost the equipped Monster's ATK. This card synergizes with Mathmech Multiplication and Loading..., which can modulate Monster ATKs when sent to the GY. However, you can easily Summon Mathmech Multiplication from your Deck using other cards instead.
Mathmech Induction
This card provides a form of disruption by popping 1 of your opponent's cards. However, since it is a Trap card, it is often too slow.
Geomathmech Magma

This card allows you to destroy up to 2 of your opponent's cards if it destroyed a Monster by battle. If you do not have a response to your opponent's Maxx "C", you can Summon Loading... to set up some board presence without giving your opponent too many draws. However, Loading... is generally a better alternative.
Other Core Cards
Balancer Lord

This card is your main starter and allows you to perform an additional Normal Summon. Furthermore, when banished, you can Special Summon a Level 4 or lower Monster from your hand. Usually, you activate Cyberse Wicckid's effect to banish Loading... and search a Mathmech Tuner. Then, you can activate Loading...'s effect to Special Summon the searched Monster. 3 Loading... are mandatory.
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 Parallel eXceed from your Deck. Since its Level becomes 4, you can use it to Summon Link Monsters like Link Devotee or Xyz Monsters like Loading.... 3 Parallel eXceed are mandatory.
Link Disciple/Link Devotee
These cards are your main Link-1 Monsters. In general, you want to Link Summon Link Disciple using your starter and Link Devotee using your extender. Then, you can activate Link Disciple's effect to tribute Link Devotee and mulligan, triggering Link Devotee's effect to Special Summon 2 Tokens. In certain situations, you can also Tribute Link Devotee with Mathmech Nabla or Loading... to Summon an additional Mathmech Monster. Note that Link Devotee locks you into Link-2 or lower Link Monsters. 1 Link Disciple and 1 Link Devotee are mandatory.
Link Spider/Linguriboh
These cards are your other Link-1 Monsters. Link Spider allows you to somewhat recover after getting hit with Loading..., while Linguriboh allows you to negate a Trap Card. If you have Cyberse Wicckid and a Token from Link Devotee on the field, you can Link Summon Link Spider/Linguriboh using the Token to trigger Cyberse Wicckid's effect. Typically, you Summon Link Spider or an extender like Mathmech Addition over Linguriboh during your first turn, which allows you to use Linguriboh against your opponent's Trap Card during your following turn. Run at least 1 of these cards (or both).
Cyberse Wicckid
This card allows you to search any Cyberse Tuner if a Monster is Special Summoned to a zone it points to. It also protects Cyberse Monsters it points to from destruction by card effects. In general, you want to Link Summon Cyberse Wicckid using Link Disciple and 1 Token from Link Devotee. You can then Link Summon Link Spider/Linguriboh using the remaining Token, triggering Cyberse Wicckid's effect to search a Mathmech Tuner. If you banished Loading..., you can Special Summon the Mathmech Tuner that you just searched. 1 Cyberse Wicckid is mandatory.
I:P Masquerena

This card is your secondary form of disruption. Usually, you want to Link Summon Loading... at the end of your turn in a zone that Cyberse Wicckid points to. Then, you can Link Summon a Link Monster (e.g. Knightmare Unicorn) during your opponent's turn. Note that you can only use non-Link Monsters to Link Summon Loading.... However, you can activate Loading...'s effect to tribute a Cyberse Link Monster and Special Summon a non-Link Mathmech Monster. 1 Loading... is mandatory.
Splash Mage/Transcode Talker


These cards allow you to Link climb into Loading... using any 2 Cyberse Monsters. First, Link Summon Loading... using any 2 Cyberse Monsters. Then, activate Loading...'s effect to Special Summon a Cyberse Monster from your GY. Link Summon Loading... using Loading... and the Cyberse Monster you just Summoned. Then, activate Loading...'s effect to Special Summon a Cyberse Link Monster from your GY. You can now Link Summon Loading... using Loading... and the Cyberse Link Monster you just Summoned. 1 Loading... and 1 Loading... are mandatory.
Accesscode Talker

This card is your secondary boss Monster. In general, you want to Summon Loading... over Geomathmech Final Sigma if your opponent does not control any Monsters OR if your opponent controls any cards that need to be popped. You can also Summon Loading... using Mathmech Multiplication to double its ATK (5300 -> 10600) and immediately OTK. Alternatively, you can also OTK without Mathmech Multiplication using Loading... (5300) and Loading... + Mathmech Addition (2000 -> 3000). 1 Loading... is mandatory.
Core Decklist
Notes
-
If you run Loading..., run 2 Mathmech Nabla and 2 Mathmech Superfactorial.
-
You can run Link Spider instead of Linguriboh (or run both).
-
Make sure to also include 1 or 2 targets for Loading....
I:P Masquerena Targets
Depending on your Extra Deck space, you can run 1 or 2 Loading... targets. Broadly speaking, Underworld Goddess of the Closed World and/or Knightmare Unicorn are strongly recommended.
-
Underworld Goddess of the Closed World can provide multiple forms of disruption. Importantly, this card is a Kaiju that can be Link Summoned using 1 of your opponent's Monsters.
-
Knightmare Unicorn can return 1 of your opponent's cards from the field to their Deck.
-
Topologic Trisbaena and Topologic Zeroboros can help deal with backrow-heavy decks by banishing all Spells/Traps on the field.
-
Apollousa, Bow of the Goddess can negate multiple Monster effects.
-
Mekk-Knight Crusadia Avramax is an untargetable Monster that is also protected from destruction by card effects when Link Summoned using Loading.... Thus, it is very difficult to remove from the field for many decks. While it does not provide a disruption on the field, it has a floating effect that non-target shuffles a card on the field into the Deck.
Code Generator Package
(NOTE: The following section was written by
, who has kindly given me permission to include it in this guide.)The Code Generator package can give Mathmechs a well-needed boost in consistency while solving the primary drawbacks that typically come with generic Cyberse extenders (e.g. taking up your Normal Summon or not setting up your GY for Mathmech Superfactorial).
-
Code Generator in hand can Link off with any Cyberse Monster to make Code Talker Inverted, netting a free Special Summon and a foolish effect. This has three purposes: first, Code Talker Inverted freely extends your plays by providing an extra Summon, typically used after Cyberse Wicckid's search. This is particularly useful when you managed to search Mathmech Nabla but have no way to Summon it. Second, Code Generator's built-in foolish can set up your GY with a missing Mathmech. However, in most cases, you can dump Dotscaper instead for a free Cyberse body. Third, Code Generator’s effect can be used to chain block Cyberse Wicckid’s search, preventing your opponent from interacting with a combo chokepoint.
-
Code Generator can also be used as part of the climb into Loading..., providing a free material if your climb gets interrupted, and optionally dumping Mathmech Multiplication for a 10600 ATK Loading....
-
Finally, Lady Debug can optionally be added to the package as a searcher. In particular, Lady Debug + any extender is a 2-card combo.
Salamangreat Package Salamangreat Balelynx is an alternative Link-1 Monster to Link Spider/Linguriboh. If you have Cyberse Wicckid on the field, you can Link Summon Salamangreat Balelynx to a zone that Cyberse Wicckid points to. When Cyberse Wicckid's effect to search a Mathmech Tuner is activated, you can chain block with Salamangreat Balelynx's effect to search Salamangreat Sanctuary. Then, you can use Salamangreat Sanctuary as a discard for cards like Knightmare Unicorn.
Adventurer Package
The Adventurer package offers an omni-negate and a bounce at the cost of being unable to activate the effects of Normal Summoned Monsters. Thus, if you choose to run this package, you usually run less copies of Loading... and Loading.... Instead, you can run Cyberse Gadget, which can Special Summon 1 Token when it is sent from the field to the GY. Note that you cannot use Cyberse Gadget's first effect if you activate Rite of Aramesir, although this is usually irrelevant in Mathmech anyway. On the other hand, Cyberse Gadget's second effect generates a Level 4 Token that can be used to Summon Geomathmech Final Sigma. You can also run Loading... instead of Cyberse Gadget as a non-UR alternative.
Other Useful Cards


These cards are your main consistency cards. Run either 3 Loading... and/or 3 Loading..., depending on preference. Loading... allows you to search any Level 4 or lower Cyberse Monster at the cost of sending 1 card from your hand to the GY. If you send Mathmech Sigma to your GY, you can then Special Summon it to your field. However, it is inherently -1 in card advantage, and Mathmech tends to burn resources from the hand at a fast rate. On the other hand, Loading... allows you to draw 2 random cards at the cost of banishing 10 random cards from your Deck. Nevertheless, it is always a +1 in card advantage. If you run Loading..., it is recommended to run 2 Mathmech Nabla and 2 Mathmech Superfactorial to decrease the probability that all copies are banished.
These cards are staples in almost every deck.



These other handtraps can prevent your opponent from establishing their board.
This card, along with Called by the Grave, can help you deal with handtraps.
This card can help you break your opponent's board.
These cards can help you deal with backrow-heavy decks.
This card can help set up Mathmech Superfactorial by sending a Mathmech Monster from the Deck to the GY. If you send Mathmech Sigma, you can then Special Summon it to your field.
Overview
Despite the deck's potential to go second and OTK, you typically want to go first instead and set up a board with Cyberse Wicckid, Loading.../Loading..., and Mathmech Superfactorial with 3 Mathmech Monsters (ideally including Loading...) in your GY. Then, during your opponent's turn, you can activate Mathmech Superfactorial to Xyz Summon Primathmech Laplacian and send up to 3 of your opponent's cards to their GY. In addition, Loading... provides a secondary form of disruption, while Loading... grants an additional omni-negate. Furthermore, if you Special Summon a Monster to a zone Cyberse Wicckid points to, you can also search a Mathmech Tuner for follow-up. Once you have successfully simplified the game state, you can then easily OTK on the following turn by Summoning Geomathmech Final Sigma or Loading....

Geomathmech Final Sigma
How to OTK with-
Summon Mathmech Nabla and any Cyberse Monster.
-
Activate Mathmech Nabla's effect to Special Summon Mathmech Multiplication from your Deck by tributing the Cyberse Monster.
-
Activate Mathmech Multiplication's effect to increase its Level to 8.
-
Synchro Summon Geomathmech Final Sigma using Mathmech Nabla and Mathmech Multiplication. Geomathmech Final Sigma MUST be in the Extra Monster Zone.
-
Activate Mathmech Multiplication's effect to increase Geomathmech Final Sigma's effect to 6000.
-
Chain activate Mathmech Nabla's effect to allow Geomathmech Final Sigma to make up to 2 attacks on Monsters during each Battle Phase this turn.
NOTE: Assuming that your opponent has 8000 LP,
-
If you Synchro Summon Geomathmech Final Sigma using Mathmech Multiplication (but NOT Mathmech Nabla), you can OTK if your opponent controls 1 Monster in Attack Position whose ATK is less than or equal to 2000.
-
If you Synchro Summon Geomathmech Final Sigma using Mathmech Nabla (but NOT Mathmech Multiplication), you can OTK if your opponent controls 2 Monsters in Attack Position whose combined ATK is less than or equal to 2000.
-
If you Synchro Summon Geomathmech Final Sigma using Mathmech Multiplication AND Mathmech Nabla, you can OTK if your opponent controls 2 Monsters in Attack Position whose individual ATKs are less than 6000 and combined ATK is less than or equal to 8000.
Loading...
Rulings on-
If Loading...'s effect is negated (e.g. by Loading... or Mathmech Superfactorial), it will still give an omni-negate to an Xyz or Synchro Mathmech Monster that was Summoned using this card.
-
The omni-negate given by Loading... does not negate continuous effects (e.g. Skill Drain).
-
The omni-negate given by Loading... must be applied to the first Xyz or Synchro Mathmech Monster that was Summoned using Loading... and cannot be applied to more than one Mathmech Monster.
Loading... + Mathmech Multiplication
Rulings on-
You must chain link 1 Mathmech Multiplication'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 Mathmech Multiplication's effect, your Loading...'s ATK becomes 2300 -> 4600 -> 7600. Furthermore, your opponent can respond to this.
-
When your opponent activates cards like Loading..., Loading...'s 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.
Other Tips & Tricks
-
Geomathmech Final Sigma deals double battle damage only when it battles an opponent's Monster, not when it attacks directly. Moreover, it does not deal piercing battle damage when it battles an opponent's Monster in Defense Position.
-
You can tribute Link Devotee with Mathmech Nabla or Loading... instead of Link Disciple to Summon an extra body on the field.
-
If you activated Mathmech Superfactorial and Summoned a Mathmech Monster in your GY to a zone Cyberse Wicckid points to, but you did not Summon a Mathmech Xyz Monster to a zone Cyberse Wicckid points to, you will still trigger Cyberse Wicckid's effect to search a Cyberse Tuner Monster.
-
If your opponent plays Harpie's Feather Duster and you chain Mathmech Superfactorial to Summon Primathmech Laplacian, when Harpie's Feather Duster's effect resolves, the game will prompt you to detach 1 material to protect Mathmech Superfactorial from destruction by card effect. In general, you do not want to do this, since Mathmech Superfactorial will be sent to the GY anyway, unless you control other Mathmech Spell/Trap Cards (e.g. Loading... or Mathmech Induction) that you want to protect.
How to Play Against Mathmech
-
In general, you want to prevent the Mathmech player from setting up Mathmech Superfactorial with 3 Mathmech Monsters in the GY. Common chokepoints include Link Devotee, Mathmech Nabla, and Cyberse Wicckid, and a well-placed interruption can prevent the Mathmech player from searching an additional Mathmech Monster to send to the GY.
-
If possible, Summon your Monsters in Defense Position to prevent an OTK with Geomathmech Final Sigma. However, the Mathmech player may still be able to OTK with Loading....
-
A Mathmech Monster that was Synchro or Xyz Summoned using Loading... as a material gains an omni-negate during the turn it was Summoned. Play around this accordingly!
-
Cyberse Wicckid cannot be destroyed by battle OR card effects. In addition, any Cyberse Monster in a zone that Cyberse Wicckid points to cannot be destroyed by card effects.
Hand Trap
Good Target(s)
Note
N/A
Mathmech usually needs to Special Summon several Monsters before creating a board with any meaningful interaction. In general, this card will end the turn immediately.
N/A
Activate this card immediately. This prevents the Mathmech player from setting up Mathmech Superfactorial with 3 Mathmech Monsters in the GY. In general, this card will end the turn immediately.

N/A
Activate this card after Link Disciple's effect resolves. This prevents the Mathmech player from activating Cyberse Wicckid to search a Mathmech Tuner Monster or Loading... to search Mathmech Superfactorial.
Destroying or negating Link Devotee's second effect prevents the Mathmech player from Summoning Link Tokens, which can be used to Summon Cyberse Wicckid.

N/A
Activate this card immediately after Cyberse Wicckid is summoned. In general, this card will end the turn immediately. Do NOT activate this card while Link Devotee is on the field - doing so will trigger its effect to Summon 2 Tokens!
N/A
Activate this card immediately after Cyberse Wicckid is summoned. This prevents the Mathmech player from activating Cyberse Wicckid to search a Mathmech Tuner Monster.



Negating Mathmech Nabla or Cyberse Wicckid prevents the Mathmech player from setting up Mathmech Superfactorial with 3 Mathmech Monsters in the GY. Do NOT try to negate Link Disciple.
Negating Mathmech Superfactorial prevents the Mathmech player from Summoning Primathmech Laplacian.

Activate these cards in response to Mathmech Superfactorial. Banishing Loading... prevents the Mathmech player from Summoning Primathmech Laplacian with an omni-negate. However, they will still be able to Summon Loading....
- What is the general game plan? What does a typical end board look like?
In general, you want to go first and set up an end board with Cyberse Wicckid, Mathmech Superfactorial, and at least 3 Mathmech Monsters (ideally including Loading...) in your GY. Depending on your starting hand, your end board may also include Loading... and/or Loading.... During your opponent's turn, activate Mathmech Superfactorial to Xyz Summon Primathmech Laplacian (ideally using Loading...) and send up to 3 of your opponent's cards to the GY. In addition, Primathmech Laplacian gains an omni-negate if it was Summoned using Loading..., and Loading... provides a secondary form of disruption. If you Special Summon a Monster to a zone Cyberse Wicckid points to, you can also search a Mathmech Tuner for follow-up. Then, on your following turn, you can easily OTK with Geomathmech Final Sigma or Loading.... Likewise, if you are going second, you generally want to OTK with Geomathmech Final Sigma or Loading....
- When should I Summon Loading... vs Geomathmech Final Sigma?
You should Summon Loading... if your opponent does not control a Monster in Attack Position, or if they control a card that needs to be popped. Otherwise, if your opponent controls a Monster in Attack Position, you can summon Geomathmech Final Sigma instead.
- Should I run Loading... or Loading...?
This is entirely up to you! Loading... allows you to search any Cyberse Monster. However, you must send 1 card from your hand to the GY. Loading... allows you to draw 2 random cards. However, you must banish 10 random cards from your Deck. As a result, you must adjust your ratios accordingly (e.g. 2 Mathmech Superfactorial).
- Why doesn't the game let me chain link 1 Mathmech Multiplication'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.
- Can I run the Adventurer package?
Yes! Although Loading... and Loading... are very good Normal Summons, the Adventurer package offers an omni-negate that can protect our combos and a bounce that can remove floodgates. Personally, I don't think the Adventurer variant is necessarily better than other variants, but feel free to try it out!
- Can I run Loading...?
Yes! Loading... is a versatile card that can search starters, extenders, or even hand traps. Loading..., Loading..., and Loading... each have their advantages and disadvantages, so I recommend experimenting to see what you like best!
Final Thoughts
And that's the guide! Mathmech is receiving upcoming support in the form of Mathmech Circular, which greatly increases the deck's consistency and resiliency to hand traps and other disruptions. Nevertheless, the deck currently remains a solid deck that can easily OTK.
If you have any questions, feel free to ask me or the Mathmech channel in the MasterDuelMeta Discord. Otherwise, if you notice any mistakes or have any suggestions, let me know! I also want to say a big thank you to the members of the Mathmech channel who provided feedback while I was creating this guide. Have fun!
