oops, sorry! didn't notice that either!
Anyway, that's fine. :) Just as a heads-up, I've already got Cottonee and Gothita. Other than that, any of the black exclusives are great!
(oh and btw, if you ever do trade w/ gts (which I'm guessing you haven't??), it is very, very random and honestly unlogical. Half of the offers on there are for level 9 Reshiram/Zekrom, which have to be hacked. Though I did get a shiny ponyta on there once, by putting up an offer??)
