Postulate of Profanation

As an additional cost, discard a creature card or
pay 2 life.
Exile target creature card from a graveyard, create
a 2/2 black Zombie creature token with menace,
it gains haste, at the beginning of the next end
step, sacrifice it.
" If the dead are going to return from their graves, then
there's nothing to stop the birds from eating the bodies.
So there's no point in our burying people."
