Kingdra if its not level 100, since then you can re-train it, and Lucario if it is level 100, since its the next best. So one of them, Groudon, Rhyperior, and Sceptile. Okay. I'll get you a Shiny stone next time we're both on.
I see, than forget uxie, kingdra and lucario are the (within what you have there) the best in ev and in nature, you might want to remove the sp. attacks from kingdra and replace with physical moves, because of dragon dance
Yh jolly is cool, but a lonely dusknoir isn't that great, since dusknoir is a defensive poke, but it's the best among them all. what is the +/- of the naughty nature?
