I've been hearing a lot in terms of how Sabledonk will become an unstoppable deck under the new BW rules. Currently there is three things which stop Uxie Donk from being a dominent deck. 1. SP can use call energy and fill up the bench with high HP basics and then power spray an uxie drop 2. Going 1st drastically reduces your chances of getting a donk. Your opponent can fill up there bench with pokemon collector, hit you with disruption techs like Mesprit and possibly get donked itself. 3. Spiritomb and Gastly starts. The only thing a Sabledonk can't seem get around is a Spiritomb start. I assume a special darkness energy would need to be used in order to take advantage of overconfident. If the oponent has only 1-2 starters which is likely when going first. FTR I don't like playing with or against Uxiedonk, or encourage anyone to play it.
