Much as I really like the system now, I feel there could be a kind of 'kudos points' system that buys bonuses later on, such as the right to regain a card, or play a fourth card in a scene, for instance. I'd model it on the fantastic 'best player' idea from Unknown Armies: At the end of a scene/chapter, the players and narrator get a quick vote on which player was the most interesting, valuable, or otherwise worthwhile player, with a reason attached. This becomes a really valuable way to permit players to compliment each other, reinforce each other, and keep everyone feeling capable, smart and creative. I'd display how many kudos points everyone has earned so far on that screen too, since it tends to spread the points around and give everyone a time in the spotlight.
