Goblin Mutant can't block creatures with power 3 or greater.
Vigilance, trample
Whenever a creature you control deals combat damage to a player, draw a card if that creature has a +1/+1 counter on it. If it doesn't, put a +1/+1 counter on it.
: Choose a creature type other than Wall. Target creature becomes that type until end of turn.
Target creature you control with a +1/+1 counter on it fights target creature an opponent controls. (Each deals damage equal to its power to the other.)
When Super Mutant Scavenger enters or dies, return up to one target Aura or Equipment card from your graveyard to your hand.
