Pokemon X and Pokemon Y

Fun fact guys: There's an option in the GTS to turn off 'special' Pokemon (ie, legendaries), and you can also filter your results by Pokemon you own.

I only found out about this the other day but it has been a God send.

Oh yeah, can somebody trade me Xerneas, I just need it for my Pokedex and you can have it straight back.
 
Sure, I'll do it. I think I have your FC already.

Mewtwo's cave is one room and he is standing in the middle.
I know, but it will still take me hours ;-;
Has anyone got any hints on how to go about it?

also, I wanna do a 4 man battle some time...
