I'll get you a Vullaby for a Rufflet once I can catch it. (Realizes Jaco knew I would say that.)
I've got an extra Gothita lying around. I have Zorua, I can try breeding it when I get Ditto. As for Tornadus and Reshiram, I can let you borrow them to complete you Pokedex (once I catch them myself), but I'll want them back. I can get an Oshawott egg from my bro. I don't need anything in return, being that I'm the only one who got Pokemon Black, I have tons of sources to get version exclusives.
