Minccino uses it to evolve to Cinccino. There might be more.
However, I would advise not using it to evolve it, only because you can catch Cinccino in the wild. It would be a waste if you used it. You can catch Cinccino on Route 9. The route with Shopping Mall Nine. Route 9 is west of Opelucid City, the eight gym city.
Minccino
You need a Shiny Stone to evolve into Cinccino.
Minccino evolves with the Shiny Stone!
Togetic, (into Togekiss) Roselia, (into Roserade) and and Pokemon Black and White, Minccino into Cinccino.
Not origanally I don't think but if you trad migrate or link Pokemon yes( the link is right outside of black city or white forest
To find a shiny stone you can trade a pokemon thats holding the shiny stone or maybe someone in your pokemon game will give you one. If you use a Shiny Stone on Minnico it will evolve into Cinnico
Minccino
One way is to go to charge stone cave and use a max repel and search
Route 6, Dragonspiral Tower, and any of a variety Cave Dustclouds.
