Lol, I rarely ever encounter taunt parties and when i do, i let them taunt for the first match, and then beat the **** out of them with pikachu or snake. It's amazing how slowly taunt parties react when they suddenly get attacked, thinking that the other player(s) is taunting with them.
In general, taunt parties are fun, especially if it's captain falcon, but seriously, if you hate taunt parties, just drop out and pray that you don't fight them again.
Or you can just get random FC's from the smash community around here.
