Whenever a creature card is put into a graveyard
from anywhere, exile it.
Whenever Grimace, Reaper of the Dead deals
combat damage to a player, you may cast a copy
of a creature card exiled with Grimace. If you do,
that creature enters the battlefield as a zombie in
addition to its other types and gains decayed.
