A friend of mine gave me his copy of Pokemon Y since I recently just got a 3DS XL. And he said I might want to do something with the Misdreavus and Jirachi that he has in his PC.

I did a little research and it seems like both of these Pokemon are only obtained in transfers? I don't know Pokemon games that well.

So basically should I bother getting someone to hold these Pokemon for me or can I just erase over his profile.
