As you can see, I have all HMs avalible to me.

I have been playing pokemon for a long time know. I have gone without critique all these years, so could you tell me how I'm doing and what I could improve so I could do well over Wi-Fi?

While this isn't exactly a competitive team, I can see you're interested nonetheless. I'd recommend some guides on EVing, competitive battling, and team building before I could actually critique your team :P

Like he said i think you have the passion, but your not informed enough. Before you actually try and put a team together read a guide on EV training the one on Serebii.com is good. That will take pokemon to a whole new level. Then look at move sets for each pokemon on Smogon University to get ideas. Then if you want watch a few narrated wi-fi battles on you-tube. That should help a lot.
