Aldrich, Devourer

Mutate {2}{u/b}{u/b}
Whenever this creature mutates, destroy target creature.
Whenever another creature dies under your
control, if it had vigilance, place a vigilance
counter on this creature. The same is true for
first strike, haste, hexproof, menace, flying, doublestrike, trample, lifelink and deathtouch.
