Whenever another nontoken creature you control
dies, exile it. Then, create a creature token that's a
copy of that creature, only it's a black zombie
(It loses all other colors and creature types.)
{t}: Exile a creature from a graveyard. Create a
creature token that's a copy of that creature, only
it's a black zombie.
The mountains attacked first. They're just returning
the favor.
