Brainstorm

Draw three cards, then put two cards from your hand on top of your library in any order.

Ana Battlemage

Kicker {2}{U} and/or {1}{B} (You may pay an additional {2}{U} and/or {1}{B} as you cast this spell.)
When Ana Battlemage enters the battlefield, if it was kicked with its {2}{U} kicker, target player discards three cards.
When Ana Battlemage enters the battlefield, if it was kicked with its {1}{B} kicker, tap target untapped creature and that creature deals damage equal to its power to its controller.
