You're going to laugh - I have everything except Meloetta for Pokédex completion now. :D Though I think you were going to trade the Cobalion, Virizion, and Terrakion for clones of the Weather Gods of Hell (why not, sounds cool). :) I'll be interested to see if they forever say caught in a faraway place even if traded back to W2 later (not that I'll need to); the different catch location means they won't be the B2/W2 versions. I found a AR code to possibly trigger rebattles with all three, so I'm going to try that and see if it works. :)
You can still get the Weather Gods however; maybe what I'll do is transfer them to W2 and get you to trade there. I'll need a few minutes to set up; going to make two clones of each, maybe even three, so I can keep one set as the set I contain within my 13 or so Pokédex boxes (001-649, all sorted) and perhaps a second set to reside on W2 (this set living there); the third set can be the trades. I'll only trade one set over for now for trades. Give me a little time to catch three junkers to send back to Black to import them? :)
