You're from Unova? [Dawn beams at that immediately!] One of my friends has been there.. though so far he only has a few badges.

Umm.. well, basically first off there's two rounds. The first one is where you show off your Pokémon by having their moves shine! And after that is the battling round, where you still have to make those moves shine and be as beautiful as possible.. but you have to also try to get as many points as possible and make sure your own Pokémon don't get knocked out.
