You never replied on the thread, so I guess I'll repost my reply to your offer here..
Hmm..
I like the Shiny Koffing, but I'd probably ask for two shinies because the Miltank has pretty good IVs and I like it very much...
How about the Shiny Koffing and the Shiny Electrode? (I also didn't make the coding- someone else made it for me.)
