Huntmaster Liger

Mutate {2}{W} (If you cast this spell for its mutate cost, put it over or under target non-Human creature you own. They mutate into the creature on top plus all abilities from under it.)
Whenever this creature mutates, other creatures you control get +X/+X until end of turn, where X is the number of times this creature has mutated.

Mutation {2}{W}
Immer wenn diese Kreatur mutiert, erhalten andere Kreaturen, die du kontrollierst, bis zum Ende des Zuges +X/+X, wobei X gleich der Anzahl an Mutationen dieser Kreatur ist.
