Keep in mind that I don't want to keep your legendaries, I just want the data in my pokedex and that's it to it really. I promise that I will give them back, if that is of your concern, you can trust me on that one.
Anyways, I already obtained Mewtwo, Lugia and Suicune. I can obtain in the game Raikou, Entei and Latios, so don't worry about that one.
I just need the data of the other leggies and that's it. So at least in the GTS I can get my own.
