I thought it would be interesting to have a 1v1 tourney but each person gets a 2nd player as a teammate who can ONLY use 1 peon to rep/scout. Maybe make it so that person starts out with 1 farm so if/when peon dies, he can watch.
And yes, opponent can kill peon. Peon person cannot make any units though. You get 1 peon and that's it. He dies in first min, he's done. If other guy's lives all game, he reps n does stuff all game.
Just a thought of something random/fun.
