Pretty self explanatory, cast big instants and sorceries with Firesong and Sunspeaker in play, gain tons of life, maybe win with that life gain through Aetherflux Resevoir, Felidar Sovereign, maybe even an Approach of the Second Sun. It's not too fun to pilot, because typically people don't want you to blow all their stuff up, but there are some fringe cases where you become an arbiter of control. Deck definitely needs work, I've got some pretty bad cards in it that need replaced with required cards like Rune-Tail for this deck.
