How about Pokemon that have already been altered? That is the real issue. Can it detect pokemon altered via 3rd party programs when they attempt to trade to 3DS even if their stats etc are within set parameters?
I just discovered this site called Pokecheck & it is absolutely frightening to see how common this is. Like the vast majority of recorded Pokemon are hacked with perfect 31 IV's & hidden powers to cover their weaknesses flawlessly.
How could Nintendo let it get this bad?
