[ORAS] OU Build (with Mega Lopunny)

[Azoth]

So, I've been going over what might be good for ORAS, so, I tweaked a team I made for B/W. I made it to try and be balanced, but, I don't have much competetive experience yet. So, I was wondering if anyone could give me any tips or suggestions on any flaws in this build. :D
