Play with your hand revealed.
If you would draw a card, reveal the top card of your library instead. If it's a creature card, put it into your graveyard. Otherwise, draw a card.
Whenever a creature is put into your graveyard from the battlefield, return it to your hand.
Whenever a nontoken creature you control enters, you may pay . If you do, create a token that's a copy of that creature, except it has haste and "At the beginning of the end step, sacrifice this permanent."
