Keldeo will finally be available and it is a Gamestop event. Is it any different than a normal distribution event like the Mewtwo one that happened a few months ago, or is it just another name for the same thing?
No. A normal event is over Wi-Fi, and you can get it at home over Wi-Fi Mystery GIft. For a Gamestop Event, you must go to gamestop to get the Pokemon.
