Perfected Predator

Mutate 2 (If this creature would untap during your untap step, you may instead put two +1/+1 counters on it.)
Whenever Perfected Predator mutates, you may have it deal 2 damage to target creature or player.
"I'm particularly fond of this specimen. The way it rends and tears at flesh ... so satisfying to watch, wouldn't you agree?"
