Empyrean Trammel

Enchant {1}{w}{w}(You may sacrifice a nontoken
creature you control with {1}{w}{w} in its casting cost to
exile this permanent, then return it to play under its
owner's control.)
When Empyrean Trammel enters play, draw a
card then exile each creature with power less than
the number of cards in your hand until Empyrean Trammel leaves play. Whenever a player draws a
card, they may return a card exiled by it they own
to play under their control.
