I want to try getting my hands on a shiny Rhyhorn by breeding. I know a way to do it, but I need either a Charmander, which I'll have to get from R/B/Y, or another Pokemon in an egg group that can bridge the gap between Gyarados and Rhyhorn.
There is a 1 in 64 chance of getting a shiny by breeding if one of the Pokemon you are breeding with is shiny itself.
I'm hoping I can trade between virtual consoles, because it would be good if I can breed for shiny Pokemon from both Kanto and Johto.
