Either way it was odd, as my 5th gen games could connect but my 4th gen ones couldn't. Well, I'm getting Kevin24 to tutor it and trade it to me on 5th gen.
Widely among us competitive battlers, shiny pokemon as rare as this simply increase their value by a LOT if they have tutor moves not accessible in the generation game that they normally battle in...
Take Chansey for example. People value Seismic Toss ones VERY highly. Why? It's 3rd gen, and there aren't many 3rd Gen Chanseys being used in the metagame--much less shiny ones.
The more inaccessible the move tutors, the more valuable the pokemon that knows those moves becomes...Not to mention I plan on cloning & using a clone of the Mew in battles...
It's completely legit, and almost nobody has one...Much less one that knows such good moves. LOL
