No worries, I didn't expect an immediate answer anyway. I don't see myself getting ahold of these otherwise any time soon.
I don't think I need him in a specific form, he should count for his slot no matter what.
Genesect and Arceus don't count for the shiny charm anyway, I believe, so they would just be my touch of OCD at having a blank spot. But the 3 you just named do and they're my biggest obstacle to higher shiny chances.
So, anytime you'd loan them to me just long enough for dex credit (after we trade for them I'd like to back out and check my dex to be sure they're in there, then immediately trade back) would be awesome <3 I'm down to only needing about 7 more pokemon, counting those 3. The rest are just Tynamo's, ferroseed, and Klang's evolutions then everything I breed for people from now on has an increased shiny chance *dances*
Shinies I will, of course, share with you for cloning so you can have them as well ^_^
