Wouldn't it be interesting to try a tournament set in the war of the roses, where each person picks a side, Lancastrians or Yorkists. And from there duels someone from the opposite side, in a match format of course. Maybe it could also be the setting of a roleplay that we actually duel in if someone challenges someone else. It could be fun!
Obvious rules would be no meta or burn, and everyone who joins makes an OC or uses and OC.
