The PoTurtle Wars

I have come up with a fun game night during and after beta. Near the release of beta, we arrange with Team Turtle a few nights a week to d play a group vs group Team Deathmatch-or other gamemodes-. But instead of just one TDM, we create three gamemode brackets, each gamemode has 100 matches. the best 51/100 wins that bracket, and the team who wins 2/3 brackets wins the war. This goes on with PoTurtle War II, III, IV, V, VI, VII, and so on. Any thoughts on this? I am open to suggestions.
