The original legendary Pokémon in Articuno, Moltres, and Zapdos are headed your way for those of you in North America and Europe who signed up for the Pokémon Trainer Club Newsletter sometime before April 22. [Thanks, Serebii.]
The newsletter is sending out codes for the above three, featuring their Hidden Abilities of Snow Cloak, Flame Body, and Static for the respective three of Articuno, Moltres, and Zapdos. The codes can be redeemed for Pokémon Omega Ruby & Alpha Sapphire, and Pokémon X & Y.
Again, if you haven’t received your code it may take a few days for some subscribers to get them. There’s no word on when the codes will expire, so it’s recommended to use them right away.
