+1: Until your next turn, whenever a creature an opponent controls attacks, it gets -1/-0 until end of turn.
-2: Reveal the top three cards of your library; an opponent makes two piles. Put one pile in your hand; the other on the bottom of your library
-8: Search each player's library for a nonland card, exile it, then shuffle their library. You may cast those cards without paying their mana costs.
