I'll expand on my idea a bit more:
There will hopefully be a minimum of 4 teams of 2. 8 teams would be fantastic though. You're allowed to play whatever characters you want, doesn't matter if they're the same or different. You're allowed to pick who you're teammates with. Of course, if you cannot find a teammate, I can have a teammate-less section where you can find someone else to be in your team. Either that or I can randomly assign teams to those left over.
Here's the format idea for the tournament:
Tournament setup as of 15:07 UTC [26/10/2013]
Each player is assigned a letter, either A or B. This will dictate who they face from the other team first. A will always face each other first, same with A. It will be Best of Three for each match and the overall team set. Let me illustrate this:
Player A Team 1 vs Player A Team 2
Player B Team 1 vs Player B Team 2
This will always be how the first two matches happen, as mentioned above. If both of the Team One or Team Two players win, it'll be 2-0. If one player from each team wins, it'll go onto a third and final set with the winners from the first two matches. For instance:
Player A Team 1 vs Player A Team 2 (2-1) <- Here, Team 1 has won.
Player B Team 1 vs Player B Team 2 (0-2) <- Here, Team 2 has one.
Player A Team 1 vs Player B Team 2 <- This will be the deciding match to determine which team wins the Best of 3.
The winning team will then proceed in winners bracket/losers bracket, and the losing team will get knocked down to losers/be knocked out of the tournament.
