Bottomless Maw

Devour Anything (Whenever Bottomless Maw enters the battlefield, you may sacrifice any number of permanents. For each permanent sacrificed this way, put that many +1/+1 counters on it.)

Insatiable Hunger (At the beginning of your upkeep, exile the top card of your library unless you sacrifice a permanent.)

Nothing is too strange to consume, nor too small to satisfy its endless hunger.
