Jerrid, Hybrid Headturner

Trample, Defender, Devour X (As this creature
enters the battlefield, you may sacrifice any number of creatures. This creature enters the battlefield with X
times that many +1/+1 counters on it.)
If you have drawn Y cards this turn, where Y is
the number of +1/+1 counters on Jerrid, then
Jerrid loses Defender until end of turn.
So many heads. So many arms. So very, very,
very hungry.
