마법물체 생물 — 늑대 기계
5 / 5
손에 카드가 없는 플레이어가 없다면 늑대 프로토타입은 공격하거나 방어할 수 없다.
If a creature can’t attack or block unless you return a permanent to your hand, and your hand is empty, you can attack or block with that creature and Lupine Prototype. This is because the legality of chosen attackers and blockers is checked before costs are paid.
