Deathtouch
Whenever a creature dies, you may pay {4}. If you
do exile that creature. Create a token that's a
copy of that card, except it's 1/1, it's a Spirit in
addition to its other types, and it has flying.
Create a black Zombie creature token with power
equal to that card's power and toughness equal to
that card's toughness.
