i, ii, iii — exile cards from the top of your library until you exile a legendary card. you may play that card for as long a the day of the doctor remains on the battlefield. put the rest of those exiled cards on the bottom of your library in a random order.
iv — choose up to three doctors. you may exile all other creatures. if you do, the day of the doctor deals 13 damage to you.
