Final reminder that this is the last day for US, Canada, Australia, and Latin American players to claim a standard Zarude. You must sign up with the Pokemon Trainers Club and choose to receive newsletters for your email address in order to obtain the code later to download him. Some anons have also recommended that you don't link your account to gmail as they've reported not receiving emails from the Pokemon Company properly in past promotions.
