Explained

What it does

A Rank 4 Xyz of 2 to 5 Level 4 Warriors. It loses 1 material in each of your opponent's End Phases and gains effects based on how many it has: battle protection, +1500 ATK/DEF, immunity, a summon lock on your opponent, and at 5, a board wipe.

Play it when

It can't be used in Advanced Format. It's Forbidden in the TCG.

Common mistakes
  • Forgetting the mandatory detach in your opponent's End Phase.

Status: Forbidden in the TCG (Sept 21, 2026 list), so it can’t be used in Advanced Format.

How it works

Materials: 2 or more (max. 5) Level 4 Warrior monsters.

  • Opponent’s End Phase (once per turn): Detach 1 material. This is part of the effect’s resolution.
  • Gains effects by material count:
    • 1+: Can’t be destroyed by battle.
    • 2+: Gains 1500 ATK/DEF.
    • 3+: Unaffected by other cards’ effects.
    • 4+: Your opponent can’t Normal or Special Summon monsters.
    • 5: Once per turn, destroy all cards your opponent controls.

Rulings in plain English

Effect types: The End Phase detach is a Trigger Effect. The 1+ to 4+ effects are Continuous; the 5-material effect is an Ignition Effect. Battle protection counts if it’s applying at damage calculation.
