Caller of the Infinite

Flying
When Caller of the Infinite dies, reveal cards
from the top of your library until you reveal a
creature with power 2 or less. Put that card onto
the battlefield with an Infinity counter on it and
the rest on the bottom of your library in a random
order.
Whenever a creature with an Infinity counter on
it dies, if Caller of the Infinite is in your graveyard,
you may pay {w}. If you do, return Caller of the
Infinite to the battlefield tapped.
