i have a friend that has like 4 shinies and ocarina's that are sellable for pokeyen, but no actual pokeyen itself. if you're willing to buy those and convert to yen in game i could ask him. believe he has every HM ocarina, or most, and Shiny 100 Arcanine, Pidgeot, Alakazam, and Gyarados. As he was working on a competitive Gary team. If not no worries.
ill buy it all at my rate
