10 / 10
수비태세, 무적

: 괴수화 10. (이 생물이 괴수화하지 않았다면, 이 생물에 +1/+1 카운터 열 개를 올려놓는다. 이 생물은 괴수화한다.)
아크로스의 거상이 괴수화했다면, 아크로스의 거상은 돌진 능력을 가지며 수비태세 능력이 없는 것처럼 공격할 수 있다.
Monstrous isn't an ability that a creature has. It's just something true about that creature. If the creature stops being a creature or loses its abilities, it will continue to be monstrous.
Once a creature becomes monstrous, it can't become monstrous again. If the creature is already monstrous when the monstrosity ability resolves, nothing happens.
Colossus of Akros doesn't lose defender when it's monstrous. It's just able to attack.
An ability that triggers when a creature becomes monstrous won't trigger if that creature isn't on the battlefield when its monstrosity ability resolves.
