Shaymin in 5th gen yes please.
File trade would be easier for me, but I can do Wifi. It just may take a few days before I can get to a place with wifi that lets me clone (I have an oooooold DS that is super finicky about wifi). Basically, as long as you're okay with waiting a few days, wifi is fine by me. Unless I beg Eiganjo to clone it for me in which case I'll have it sooner XP
