Extra Note: this is just random combinations, don't take it too seriously. you would also have to consider synergy which i tried to do a bit by putting in teams with another player of their current team. also just took out the non na players to make it more interesting. the only team i see changing the roster is 100t. challengers teams probably won't let all their players go too.
