Odahviing

Flying, vigilance, haste
Whenever Odahviing attacks, look at the top
seven cards of your library. You may cast an
instant or sorcery spell with mana value less than
or equal to Odahviing's power from among them without paying its mana cost. Put the rest on the bottom of your library in a random order.
