Let's hope trainers don't run in to any problems when they go pick up the code card for their special shiny Gengar. Starting October 13 and through October 26, folks will be able to visit participating GameStop stores and grab a code card unlocking the shiny Pokémon.

Gengar comes with its Mega Stone, Gengarite, so it can unleash powerful attacks. It also comes with the move Sludge Wave, which it can't learn at all in game. Sludge Wave inflicts damage on all other Pokémon in battle, including teammates. It also has a small chance of poisoning targets, too.

Along with the shiny Gengar release comes a brand new set for the upcoming Pokémon TCG: XY -- Phantom Forces set. Also available at GameStop is a pack of new cards including Gengar Spirit Link, a trainer card. The rest of the set will be available in early November.

Don't forget to look out for your chance to get Diancie later this month.
