Well, that seems like the older, more mature gamers would have picked overused pokes with good training, while the younger kids would choose 'Uber' legendaries. I guess they still wouldn't have good moves and stuff, though.
Honestly, they should have divided the tourney into two, for experienced and less experienced players, if possible. It's never a good scenario when more experienced players get mixed up with newer players who are just there to have fun.
