Explained

What it does

Send a "Mathmech" monster from your Deck to the GY to Special Summon it from your hand, but you can only attack with 1 monster that turn. When a Mathmech is Normal or Special Summoned to your field while you control it, add a Mathmech Spell/Trap.

Play it when

In Mathmech decks, as its only copy. It's Limited in the TCG.

Common mistakes
  • Forgetting you can only attack with 1 monster for the rest of the turn after its summon effect.

Status: Limited in the TCG (Sept 21, 2026 list), so you can run 1 copy.

How it works

  • From the hand (cost: send 1 “Mathmech” monster except “Mathmech Circular” from your Deck to the GY): Special Summon this card. For the rest of the turn, you can only attack with 1 monster.
  • Trigger: If a “Mathmech” monster is Normal or Special Summoned to your field while you control this card, add 1 “Mathmech” Spell/Trap from your Deck to your hand. Not in the Damage Step.

Each effect is once per turn.

Rulings in plain English
