It That Devours

When It That Devours enters the battlefield,
exile all creatures into a face-down pile, shuffle
that pile, then reveal cards from the top of that
pile until you reveal It That Devours. Put all
creature cards revealed this way under their
owners' control and turn the rest face up. It
That Devours gains all abilities of creature
cards exiled this way.
"It's learning where it fits on the food chain and I'm
not sure you want it to figure that out."
