Flying Whenever Lurker on the Walls attacks, reveal the top three cards of defending player's library. Exile one of them, then play it without paying its mana cost. You lose life equal to its mana value. Put the rest of the revealed cards on the bottom of their owner's library in a random order.
Choose a nonland card name. Search target player's graveyard, hand, and library for any number of cards with that name and exile them. That player shuffles, then draws a card for each card exiled from their hand this way.
