Boltspeed Serpentine

Flash, flying, haste
Megamorph {u}{r} (You may cast this card face down as a 2/2 creature for {3}. Turn it face
up any time for its megamorph cost and put a +1/+1 counter on it.)
When Boltspeed Serpentine is turned face up, creatures you control gain haste and you may play creatures as though they have flash until the end of the turn.
