Legit hacks flat-out makes no sense, because each part contradicts itself. Legal hacks, however dumb it may be, the stats and moves of the Pokemon are legal, so that part makes sense. Nothing about it is legit, though.
So you're going to insult me? If I'm going to test out new sets for Pokemon I'll use whatever the heck I want to use. If it happens that the current batch of Pokemon I'm testing are stall, then so be it. It's wifi, it's going to happen. Go play on Shoddy if you don't want to "waste your time" playing a video game.
