It's been a while since you posted the request. Can you verify for me whether you received one of your pair, and which one you still need? I'm guessing you still need a Meloetta, and I have a few I can list and offer. Two I believe have excellent stats, but I'd have to clone them as I haven't done so with those ones yet. :)
I also have a Lv.15 Meloetta that is Japanese and the first Meloetta available, and another Meloetta or two sitting in Black right now, not counting anything in W2.
