I have a spreadsheet of my Ditto collection here, I need the ones I don't have marked as having, and I offer the ones I have multiples of. I also have a lot of HA pokemon, and some IV'd drought vulpix, magic guard abra, and moxie heracross.
Or just ask for something I can let you know if I have it. I have completed the Kalos dex so I have plenty of dex fillers. Thanks.
