For a limited time, you can get the Mythical Pokémon Diancie for your Pokémon Omega Ruby or Alpha Sapphire game! Diancie is available via a Nintendo Network distribution July 24–27, 2015.
This Diancie is as talented as it is elegant, appearing with a collection of moves that make it ready for battle. Don’t forget to look for the Diancite Mega Stone in your Pokémon Omega Ruby or Alpha Sapphire game. This item will allow Diancie to Mega Evolve! [via] [more]
