"Mathmech", known as "Processlayer" ( (ザン) () Zanki) in the OCG, is an archetype of Cyberse monsters with various Attributes introduced in Deck Build Pack: Mystic Fighters.


Each member wields a weapon or is holding one in a way that denotes the mathematical symbol it represents.

Playing style

The archetype's main goal is to set up an OTK using "Flame Mathmech Final Sigma" who is unaffected by card effects and deals double the damage when battling monsters whilst in the Extra Monster Zone. It does this by quickly swarming the field with the various effects of the Level 4's, some of whom have ATK altering effects when they are sent to the GY e.g. "Mathmech Multiplier" doubles the ATK of a Cyberse until the end of the turn allowing "Final Sigma" to deal out massive damage.

Alternatively, the archetype has powerful removal in the form of "Batch Mathmech Laplacian" which has a "Trishula"-like effect that allows it to send opponent's cards to the GY, avoiding targeting or destruction trigger effects.

Recommended cards

"Balancer Lord" and "One-Time Passcode" can put themselves on the field without wasting a normal summon for additional Synchro or Xyz material. "Backup Secretary" gives easy access to Level 7 Synchros while also being a simple tribute fodder for Nabla or Division's effects. "Cynet Mining" and "Cynet Backdoor" can search all of your Mathmech monsters.

"Link Disciple" is a Link 1 that takes any Level 4 or lower Cyberse-type monster, which makes it the easiest monster to get in the Extra Monster Zone and tribute for Division's effect. "Cyberse Wicckid" can be used to search for Nabla and Sigma. The combination of "Transcode Talker" and "Update Jammer" can put very high amount of damage on the field with only 3 monsters.


Being a Archetype composed of entirely one type of monsters, They can be crippled by "There Can Be Only One".

Spending multiple resources to go into Final Sigma can still be knocked out with a simple "Kaiju" monster.

Since the deck focuses on Synchro and Xyz monsters, it can be partially disabled by "Dimensional Barrier"
