When Vicious Slasher is put into your graveyard
from your library, destroy target creature with converted mana cost 3 or less.
Convergence 3 (If this card is in your
graveyard, you may exile it and 3 other creature

a 0/0 black Zombie creature token with three
+1/+1 counters on it. Activate only as a sorcery.)
Every corpse is a potential threat.
