As we reported last month, mythical Pokémon for X, Y, Alpha Sapphire, and Omega Ruby are being distributed throughout the year. Each month will feature a different monster.
For February you can get your Mythical Mew by popping into a GameStop and nabbing a card with a special code on it. Since each location only received a limited number of cards, it might be best to check in with your local store now rather than later to secure yours.
Next month you won’t have to go anywhere as long as you have access to Wi-Fi. Celebi will be available right through the Nintendo Network.
