HOLY stuff POKEBANK IS OUT
I'm considering maybe getting myself an illegitimate shiny or two using action replay on diamond, then trading it up to x and y.
That might not work. Nintendo added a illegal pokemon filter script and you could lose your pokemon transporter/bank privelidges.
Wasn't considering doing this but source?Also got my Celebi that I'll probably never use.
According to Serebii you just have to store Pokemon in the Bank from X&Y, then the next time you open the application you receive Celebi
