I have 5 games therefore I have 5 dialga. If you have any of the new games:Black,white,Black 2 and white 2.I don't know if the game allows event Pokemon to be traded. I think we should try at least. And let me know if you want to do it.But here are some of my friend codes from 2 of my games:
Black 2: 2881-8368-8393 and white: 4856-5764-4893.
