The "Sky Slam" deck lets you take control of the game with tricky blue spells, and then your big flying creatures will really deliver a beating. You won't always attack much in the beginning of the game, but by the end, you'll be on top of the world. Blue magic is all about control. Unsummon slows your opponent down by bouncing a creature back to his or her hand. Besides preventing the creature from damaging you, this also makes your opponent waste time paying for the creature again!
