La criatura objetivo que controlas con un contador +1/+1 sobre ella lucha contra la criatura objetivo que controla un oponente. (Cada una hace un daño igual a su fuerza a la otra.)
If one of the targets is illegal when Mutant’s Prey tries to resolve (for example, if the first target creature no longer has a +1/+1 counter on it), neither creature will deal or be dealt damage.
Only a creature with a +1/+1 counter on it can be chosen as the first target of Mutant’s Prey.
