Uxie can pull of a decent Sub CM set with Giga Drain and Psychic, actually. Pivot into setup bait, set up a Sub, get off a CM or two, and sweep. Sponges attacks easily and hits surprisingly hard. I use it on my team to wreck teams that can't set up Toxic before I Sub. I get beaten by Chansey and Dark-types not named Crawdaunt, but Chansey dies to Lando-T and Darks get beaten by him as well.
