Calibrated Blast

“Reveal cards from the top of your library until you reveal a nonland card. Put the revealed cards on the bottom of your library in a random order. When you reveal a nonland card this way, Calibrated Blast deals damage equal to that card's mana value to any target. <br> Flashback 3RR <em>(You may cast this card from your graveyard for its flashback cost. Then exile it.)</em>”
