IMO as long as it's a legal pokemon and you tell people that you are battling with that it's a hack or that you use legal hacks, I don't see any problem with keeping it to use in battle. Don't trade it or breed it though and please don't Wonder Trade it. Keep the infection from spreading =PThanks wanted to be sure as I got that in a random trade for a level 1 Amura that was the first hint. So what should I do with it? Breeding fodder for Legit Pokes?
And I kinda figured but wanted to give the bloke benefit of the doubt.
