Gluttony, Sin of Hunger

Menace, Devour 1 (As this enters the battlefield,
you may sacrifice any number of creatures. This
creature enters the battlefield with that many
+1/+1 counters on it.)
At the beginning of your upkeep, you may
sacrifice a Food token. If you do, put a +1/+1
counter on Gluttony and each opponent looses X
life. If you don't, you loose X life where X is
Gluttony's power.
