I really am scared to use Pokecheck though as I just have no idea if the Pokemon will pass the legitimacy check. I heard editing a Pokemon in any way can cause a hack check to catch it but at the same time the stats on these mons are completely accurate as is the obtain info and moves.
If you can RNG for shininess, you can RNG for IVs.
Don't use Pokemon from Pokecheck in VGC. Pokemon from Pokecheck are not legitimate.
