+1: Place a stun counter on target creature. That creature loses vigilance and can't gain vigilance until your next upkeep.
-2: Deal 3 damage divided between any number of target creatures you don't control. Tap each creature dealt damage this way.
-10: Exile each nontoken, nonlegendary creature you don't control and place 3 time counters on each. If they don't have suspend, they gain suspend
