Diancie and Eon Ticket

[feicui]

Diancie is available for X/Y if you go to Gamestop/GAME/JB Hifi and grab the serial code.

As for the Eon Ticket (which people familiar with Ruby/Sapphire/Emerald might be familiar with as the method to unlock Latios and/or Latias), its distribution method for ORAS will be unique in that the primary way to get it will be if you get lucky on Streetpass. If you manage to Streetpass with someone who has it, you'll receive a copy yourself.
