I thought a bit about how the current roleplaying rules would work in a casual-but-still-competitive tournament. My feeling is that the Ante Manipulation abilities (page 26 of the rulebook) aren't right for tournament play. They're OK in a home setting where players are accustomed to picking on each other week after week, but they're both vindictive and distinct from the way the game usually takes players' money, so no Ante Manipulation abilities in this tournament.
To help the fighter/barbarian types who are most likely to have the Threats & Promises ability we just ruled out of the tournament, here's a new Card Draw ability that's for characters with muscles. Like the other Card Draw abilities, Getting Angry Now lets you draw two cards when it triggers.
If you bring your own character, the folks running the tournament will help you you select abilities that are right for the tournament. If you're showing up to play and you don't have a character ready, here's the short list of possible character archetypes I put together for WizKids to work from. These archetypes use the abilities as printed in the rulebook, with one exception: the Desperation ability is fine, but could get irritating if used too many times in a game, so for tournament play I'm suggesting that each player with the ability can only use Desperation once per game. Since it's therefore one of the weaker abilities, characters with Desperation will also have another ability that's on the weaker side, so they'll never be entirely out of options.
