Yeah, in the stone shop in Lumiose there's a guy that sells Mega Stones for the starters. The more stylish you are, the cheaper they become, but they start out at 1mil each. He has a different stone each day.I had greninja in my party and realized how many weaknesses it had so I searched for a Blastoise in GTS, traded a Yveltal for it. I don't feel bad.
And that blastoise is so damn well ev trained So I ask, anyone has a mega stone for blastoise? I need one so badly ;-;
