Basic Spell: Raise Skeleton

As an additional cost to cast this spell, exile a
creature card from your graveyard.
Create a 1/1 black Skeleton creature token with
"When this creature dies, you get a pact counter.
Then at the beginning of your next upkeep, if
you have a pact counter, you may remove it and
create a token that's a copy of this creature."
"I suppose you'll do for now; hope you don't mind
doing a bit of leg work."
