Hey, Tesseract!! It's Aio! I managed to get the hang of all this forums stuff. Uh... I read your post stuff and i realized that you're looking for a Timid Shaymin with HP Fire/Ice? I have a Timid one with HP Ice from my Platinum that is from Flower Paradise that i caught myself, and i could offer up to you if you'd like for the Chatot. If not, i have an event one that's spanish with the Timid nature and HP Ice. Also, if you're looking for any other things from Gen IV with special tutor moves, etc., just find me on SPP or i'll check back with you here on the forums. Looking forward to hearing from you.
My FC is 1936 0257 9032
Thanks!
