From now until May 24th you can go to gamestop and get a Darkrai code card. This will allow you to download your very own Darkrai to your pokemon ORAS/XY. There is no other conventional way to get this pokemon, so pick up yours today!

It has also recently come to my attention that my dates for the pokemon Sun and Moon release were incorrect. The actual release date is sometime in the 2016 Christmas season.
