You can join this tournament if you want. You just need functioning Wi-Fi. All you do is go to the sign-up thread in the announcements section, read the rules & procedures & whatnot & then sign-up with your game and Friend Code. Then, when the tournament starts, you check back at the thread to see who your battle partner is, input their Friend Code into your Pal Pad on Pokemon, organise when to battle, then do the battle and then report back.
