Special distribution runs from today through November 16
One of the promised Pokémon X and Pokémon Y distributions is here, with participating GameStop stores now offering a special code card that unlocks Diancie. The distribution runs through November 16, and players will be able to transfer Diancie to Pokémon Omega Ruby and Pokémon Alpha Sapphire when the full remakes hit Nintendo 3DS on November 21.
When the time comes, Omega Ruby and Alpha Sapphire players will be able to take Diancie to a Pokémon Center in the game and get a Diancite Mega Stone to turn Diancie into Mega Diancie. See a preview of both in the trailer below.
