Reprocessor Beast

Mutate 2 (If this creature would untap during your untap step, you may instead put two +1/+1 counters on it.)
Whenever Reprocessor Beast mutates, you may exile target card from a graveyard. If you, put a +1/+1 counter on target creature.
Nothing is wasted in Malacol. The creatures too weak to survive are recycled by monstrous digestion into sustenance for the strong.
