Welcome to PC! It's a pleasure to have you here, and I hope you enjoy your stay with us!
Like Archy said, if it's competitive battling you're after, you'll want to check out Battling & Team Building for tips, tricks, and willing test subjects--I mean, opponents. Hehe. I've been out of touch with the competitive scene since Gen V, but I wish you the best of luck in your exploits!
If you need anything or just want someone to chat to, feel free to drop me a line anytime. I look forward to seeing you around on the forums~
