I got it for free via WT (though I usually trade some awesome breedjects anyway), so literally all I'm doing is putting it in the Daycare with a Ditto; BTW, what nature do you want?
So what do you have that you think would be a good trade? I'll let you decide that; I have a full Black Dex, so other than possibly looking for a few imports without going back (which isn't a big deal), there's not much I don't have. This isn't befitting of an Event exchange (and if it were, I'd clone and eventually send it back anyway), and I can breed 5IVs easily with only some Egg Moves being a challenge (try Seismic Toss and Mud Bomb on a single Chansey or Happiny, which I'm about to pull off with Heal Bell, which was requested, and HA to boot). So you decide what you have that's worth a trade. Any Vivillon patterns I don't have? (There are a few.) Anything with an HA that you breed? You decide. :)
