Had a big 6v6 tag team event with tag lucha libre rules to allow more people to play. I came up with this move that emulates when all the members of the match jump in and brawl it out.
Brawl For All: When everyone on both teams come into the ring, roll +Look
10+ You clean house. Your team retains control, and you choose who is legal on both teams and everyone on your teams gains 1 Momentum
7-9 You looks okay. Give up control to the enemy and gain 1 Momentum, or retain control.
6- The enemy cleans house. They retain control, all gain 1 Momentum, and choose whose is legal on both teams.
Nice! How did it work in play? How do you determine who rolls (is it the person with current control of the match, or the instigator of the brawl? Or was is just obvious in the moment?)
Worked well. Only did it once, but that kind of thing is fine for one, maybe twice a match. I had it that the person in control at the time made the move, though I could definitely see the instigator interrupting and making it too.
