+1: Exile the top card of your library. You may play it this turn. If a noncreature spell is played this way, surveil 3.
-3: Create a 2/2 blue wizard token with prowess and "Whenver this creature attacks or blocks, it connives".
-9: Each opponent sacrifices all creatures they control, for each creature sacrificed this way, deal 2 damage to that opponent and draw a card.
