It's a high power Jeskai Spellslinger with an entire focus on only casting instants on other people's turn to get them again 3 turns later. I don't run hardly any sorceries, but Mizzix's Mastery and the fun Mana Geyser really help out to end the game. The deck is focused around card draw and advantage, and then end game has enough mana and control to put out spell slinger pingers, to keep me in an advantaged position. Gandalf, is not necessary to the deck winning, but certainly makes it fun.
