I both do and do not have access to one. I have access to one because I own Pokémon XD Gale of Darkness, but I am studying abroad right now (without access to my GameCube) so it'll be a few months before I can get one. If you can wait until late December or January I can get you one.I realise it is unlikely, but does anyone have access to a Helping Hand Rhydon? Would be more than happy to breed / tutor a thing or two in gen 6 or 7 in return.
Edit: One side note is that the Helping Hand Rhydon cannot be SR'd for (aside from starting a new save file) since it is caught during the final fight and the game forces you to save before you can check it.
