Oleera, Verdict of Pain

+1: Create a Madness artifact token. It has "Tap, Sacrifice this artifact: Target player cannot play spells this turn."
-3: Discard your hand, then draw that many cards. Put an Indestructible counter on Oleera, then proliferate.
-9: Remove an Indestructible counter from Oleera: Opponents each lose 9 Life, you gain Life equal to the total Life lost by all players in this way.
