dang sorry i was out for a while. Yes it is basically. It goes like this:
It's a double battle tournament in which each person has 6 pokemon(in the battle box) they use 4 each battle. No two same pokemon or items allwoed, all get put to 50, and everything that can be used in the subway can be used here(note sky drop and dark void are banned.) First there's a regionals, everyone in the region battles(for example there one in philidelphia in april 15th):One battle per two people takes place. if someone loses they get put 1 loss and you get one win, advancing to next round. You have to have 6 rounds of victory, thus beating the 2nd place person. People who come in top 4-1 or 1-8 get prizes and invites to nationals and other prizes including money 3ds's and more (the person in 1st gets a prepaid trip to nats in indianopolis, 2nd/3rd/4th place get 600-300 dollars for it.)
