I have Volcanion and Genesect codes, both PAL, I'd really like Shaymin or Mew if you've got any available. Again, a dex completion thing. I'd go for Celebi if not.
I don't have a spare Mew, but I still have a GF Shaymin to pick up. I'd trade it for your Genesect code.
Do you want a particular nature for the Shaymin, or just any?
