Legendary Pokémon Diancie is available via a distribution at GameStop stores in North America starting today, The Pokémon Company said this morning. The Diancie distribution will last until November 16th.
In order to grab Diancie, you’ll need a copy of Pokémon X or Pokémon Y. Once you have Diancie, you’ll be able to transfer it to the upcoming Omega Ruby and Alpha Sapphire games, in which you’ll receive a Mega Stone that will allow it to Mega Evolve.
