Like i said the person needs to be VIABLE and DECENT. Bringing a team with lower used pokemon (not saying they arent good) will not count. For example if someone brings a let's play team or a team with all Dogs, or simply put an NU team. Since I know Princess's team she uses a Thunderous, Cresselia, Garchomp, Rotom H, Ludicolo, and Mega Venasaur. This is a pretty good team on paper so beating a team with Dedenne, Marowak, Muk, and other underused pokemon would not seem fair. Not saying they arent good and that they cant win with them, just stat wise Princess' team has the clear advantage.
