2 Level 2 monsters While you control another "Ghostrick" monster, your opponent's monsters cannot target this card for attacks. Once per turn: You can detach 1 material from this card, then target 1 monster on the field, with ATK less than or equal to the combined ATK of all "Ghostrick" monsters on the field; destroy it, and if you do, that Monster Card Zone cannot be used as long as you control a "Ghostrick" monster.
