I like azelf in ubers, as it can kill one or more pokemon with focus slash, I run:
Azelf@Focus Sash
252 Speed/ 252 Sp. Attack/6 Hp
Nasty Plot
Shadow Ball
Explosion
HP Fighting
You can kill the psychics out there with shadow ball, and hp fighting takes care of tyranitar. Normally I use Nasty Plot, then get saved by the focus slash, then sweep, and explode when there's something that walls you.
