I'm currently in Pokemon X, but I got Moon. Just for clarity: you do mean normal Sun/Moon right, not Ultra Sun/ Ultra Moon? Not that it's a problem if you mean Ultra Sun/Ultra Moon. Just to make sure I don't boot up the wrong game if we end up doing this.
You might have to refresh me on how trading works in those games, I havent done any trading on the 3DS pokemon games in years.
What shinies do you have on offer?
