Do whatever you guys want. If I see a trade thread with random breedable pokes, and then I'm fighting against Perfect IVs pokes something's wrong IMO. I'd take a serious team, not just random perfects I got in my Black.
If you use legal hacks, it's your DUTY to inform your opponent about that, this is my point, not the fact I disagree with my loss.
