Calibrated Blast (MH2-405) - Modern Horizons 2: (tombstone) Etched Foil

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.
Flashback (You may cast this card from your graveyard for its flashback cost. Then exile it.)
