I needed a rufflet in my black 2 version and my sis has one on her white 2. She was on GTS and offered a braviary(I only seen braviary and not rufflet) for a Mandibuzz(which I hav). Then I went on my black 2 and filter for the braviary and they said none were found. Whats happening?!
Someone probably has already traded their Mandibuzz for her Braviary when she deposited it on the GTS, or you may have opened it up before she even deposited it.
