Oh shucks, is Defense really the IV that she's missing? Boy does that put a damper on this offer. ;w; I'll still take her for three as stated however!
Well, I said that Volcanion is worth 4 normal Shiny Pokemon or equivalent, and I have a chart of equivalencies (which basically boils down to 1 normal Shiny = 1 normal Event and vice versa). Since I'll put that Sawblu at 3, there would still be 1 more needed for Volcanion.
BUT if you don't mind trading me a nicknamed and unnicknamed version of that Swablu, I'd be happy to do Volcanion! (So I would clone it, send it back to you, have you nickname the clone, then send it back to me. This is on top of already cloning it so you won't lose her, of course~)
