So basically they will get the pokeballs they did the draw with the 4 playoffs teams pick one randomly (probably be fnc cuz it's rigged) and then that team choose their opponent and then they go to the next team
the order the #1 seeders get to pick is gonna be randomly decided so truly only 3 teams get to somehwat pick their opponent and one of em is getting the leftover, just based on luck, honeslty I think it's a dumb system
