I was on GTS Negotiations and it actually lasted a long time, and filled in many of my gaps. Thats something wierd.
Oh, I got a shiny Delibird for an Ursaring, and seems legit. Got a shiny Porygon Z, but I think the likelyhood is that its hacked, but I only have it to fill my pokedex gap really.
Off topic a bit, but what do you tend to look for on the GTS. I mean, I'm really only looking on there for pokemon I cant breed/evolve/catch at the moment. For some reason, Nosepasses seem slim on the ground, as well as Probopasses.
