Gluttony

Menace
At the beginning of your upkeep, if Gluttony is
in your graveyard, you may pay {2}{b}. If you do,
create a 2/2 black Zombie creature token, then
exile the top card of your library for each
Zombie you control. For each creature card
exiled this way, put a +1/+1 counter on that
token.
