Meldorax, Arcane Pursuer

{t}: You may cast the next creature spell you cast
this turn as if it had flash. When you do, that
creature spell becomes an instant in addition to
its other types, and Meldorax, Arcane Pursuer
deals damage equal to that spell's mana value to a random target opponent.
Whenever Meldorax deals damage to a player,
reveal a random card with mana value less than
or equal to the damage dealt that you own from outside the game, add it to your hand.
