What would you take for any of the Latios (don't care wether it's 5 IV or 6IV [though I'd like to know which one is the missing IV]) I don't have a lot to offer tbh but I'll start low I guess and work my way up since I need a good Latios bad.
Uh I got a flawless HP Ice Honedge (Quiet)
Flawless Modest Goodra (gooey)
Flawless Jolly Garchomp (rough skin)
Flawless relaxed Ferrothorn (with leech seed, and stealth rock)
And that's all I have for now. I have a perfect 6 IV ditto that my friend gave me so I can breeding anything you might want though I doubt that sounds impressive at all >_> (also I'm willing to trade unevenly, as in for than 1 of my pokes for your Latios)
I'd be willing to give you the ditto if you can clone it and return it c: (Ditto is Japanese if that sweetens the deal at all)
