So speaking of OWTF winning games last minute, I finally played against that card last night. This guy was running a very competitive Ambush eRey/eHan deck, and I was running eRey/eQui-gon with a shield based deck. I lost Rey pretty quickly, but Qui-gon was able to solo the other two heros very well, bringing Han down to one health. Then, using the 2 Focus from One with the Force, turned his dice to ranged damage and blew Qui-gon out of the water, winning him the game.
So yeah, it's a powerful card.
