All right. Is Impish what you want, then? I also have Hasty, Sassy, Adamant.
I'm worried that someone might get a Deoxys or Ho-Oh before you find the DeepSeaTooth and want the Impish one; if so, would you be okay with Hasty, Sassy, or Adamant instead? If not, I have the Pokemon Colosseum Bonus Disc, I can farm some more Jirachi, it'll just take some time. But I doubt anyone will get back to me before you get the DeepSeaTooth, I just wanted to warn you, because I desperately need Deoxys and Ho-oh, whereas Latias and DeepSeaTooth are things I can get myself, just... with effort. :)
