It would be a Hasty counter Absol in a premier ball. Ideally it would be shiny, but I don't believe there's a way to get certain shiny spreads in emerald (clue me in here) like there is in DPPt and HGSS. I was thinking if that is possible for you and you're interested, maybe I could do the work of trying to get a good shiny spread for it and then send the file to you. You'd probably have to walk me through it though, as I haven't touched an emulator/rom in about a year when I was trying to help equinox with shiny breeding, and I don't have a flashcart or anything like that.
