In the tournaments for triple triad I believe you get more points for defeating higher ranked players. I think it would be cool to have a player's current ranking in the tournament visible when examining a character if they are participating. also I think there should perhaps be a seeking game indicator, like an icon beside the players name. The challenged should be able to perhaps filter who can challenge them according to challenger standings.

Also, instead of walking up to people to battle, there could be some sort of interface at the tournament board, like you could go there to seek a match against other players. the interface would be like the market wards or somthing where you see all players seeking a game and range of eligibility, if they could filter who challenges them. or players can be seperated into tornament divisions seperating who can challenge who.
