From October 15th to November 5th, you'll be able to obtain a Serial Code to receive a special Shiny Gengar at GAME Stores. This Gengar comes holding the Gengarite and matches the event being held in Japan later this month, and is to tie in with the upcoming TCG set, Phantom Forces.
Next, from November 6th to November 28th, you'll be able to get a Serial Code to receive the Mythical Pokémon, Diancie. As known, this Diancie can only be obtained through this event and, when traded to Omega Ruby & Alpha Sapphire, gives you the Diancite item to Mega Evolve it into Mega Diancie

In North America, for a short time, you can go to Gamestop stores in the USA and receive a special code for a Diancie, to tie in with the new movie, Diancie & The Cocoon of Destruction. If you trade it over to Omega Ruby & Alpha Sapphire, it'll activate an event to get the Diancite item
The date for the NA release is different from the European one, just saying.
