I've been using this set for Salamence on Shoddy and it has worked wonders. 
Salamence@Life Orb
Naughty; 116 Atk, 252 Sp.Atk, 140 Speed
Outrage
Fire Blast
Earthquake
Draco Meteor
The new MixMence, it would seem. EVs give it 319 Sp.Atk, 368 Atk, and 271 Speed. While the other MixMence struggled against 252 / 108 / 148 Bolb Cresselia, this version has a good chance of bringing it down in 2 hits, and it is almost assured with Stealth Rock down. It rips through walls like there is no tomorrow, and it doesn't worry about being locked into any attacks other than Outrage, unlike CB Mence. Blissey, even if it carries max Def, is easily 2HKOd by Outrage, especially if hit by Draco Meteor on the switch. 
The only thing that lets it down is the relatively low speed, but otherwise it works great. Wish support from Jirachi is preferable.
