Welcome! I see you're interested in the competitive side of battling? Well, look no further, as here at PC we have a section that's called Battle Center. Visit there and you'll be on your way to battling. If you prefer wifi battling, we have a sticky thread for that. If you battle via Pokemon Showdown, we have our own server for that! Go to that section for more details. You can learn a lot from battling, whether competitive or casual. And no matter what level you are. Battling, however, can get you to meet incredible people, and make new friends. :)
Well, hope you have fun at battling and good luck! Don't hesitate to ask questions if you like, ok! See ya around!
