A deck I have been playing along with UB Phantom Wight, Faerie Gush-Rites wins by tempoing the opponent to death, with a high chance of winning the game immediately at almost any turn. The deck is currently incorrect as there are too many gushes and rites mainboard, but I am not sold on a particular number yet.
