Hiya J wlternova! Welcome to PC! Glad you joined :)
I too am a huge fan of both Omega Ruby and Alpha Sapphire! OR is my main, but I've been playing through Alpha Sapphire for an additional playthrough. Amazing games, both! I see Dragon has already pointed you towards Trade Corner and the Battling & Team Building sections, but you might also be interested in our
Pokemon gaming forums. We even have a thread dedicated to friend code sharing, in case you're looking for some Wi-Fi battles.
Have fun! Let me know if you ever want to battle or trade with me!
