Cobblecorpse

Delve (Each card you exile from your graveyard
while casting this spell pays for {1}.)
You may have Cobblecorpse enter the battlefield
as a copy of any creature card exiled with it,
except it's a Zombie in addition to its other types
and enters with an additional +1/+1 counter for
each other creature card exiled with it.
No bone left unturned.
