I've skimmed this thread and the previous two, and I haven't seen this set yet. (But if somebody has already posted this, just tell me and I'll replace it with something else)
Staraptor@ Focus Sash
4HP/252Atk/252Spe and Adamant (a +Speed nature isn't necessary)
-Brave Bird
-Close Combat
-Endeavor
-Quick Attack
The trick here is to come on a starter, lets say a 6 DD Gyarados, for example, while stealth rocks aren't up, after sacrificing your lead to get up some rocks and spikes of your own. Gyarados, comes in, Waterfalls (or Stone Edge, if he's feeling particularly ballzy or suspects a switch to Vaporeon), and brings you down to your sash. But what's this? It appears that Gyarados has been brought down to 1 HP, and is soon to fall victim to a Quick Attack, putting his potential 6-0 to a full stop.
Now, this doesn't always have to revenge leads, but it is preferrable that SR isn't up, for obvious, Sash-breaking reasons. He doesn't mind having Tyranitar coming in, at 1 HP or not, because no self-respecting Tyranitar enjoys a Close Combat, being made of rocks and darkness as it is. However, Rotom and any of its mechanical manifestations wall circles around the poor avian, but then again, so do the other Ghosts. His main purpose is to stop any rampaging threat dead in its tracks, and it has done just that many times (the 6 DD Gyarados being an example).
A common revenger for him would be anyone with a priority move, Scizor being a prime example, in which case, you can either Quick Attack in your death throes, or switch to a suitable counter and save your plucky avian for later.
If you are facing a slower foe, always start out with Close Combat (even if it's a resist). The lack of Life Orb recoil will create the assumption that it is holding a Choice Item, after which case they'll switch in to a suitable counter (whose name may or may not be Zapdos). Close Combat again to keep up the ruse, and when you are inevitably shot down, endeavor and have a Pokemon with a priority move clean up.
I've never tried this in UU, but it has saved my ass countless times in OU. Its best use is to revenge a lead like Starmie, who can just blow away any rocks that have been set up.
If the Sash is broken, however, and your spinner is incapacitated, Staraptor still packs a punch. The recoil from his 120 base power STAB isn't necessarily a bad thing, as he can endeavor a wall that he would otherwise have trouble against and leave it to another Pokemon to clean up. His STAB priority move can clean up some of the frailer, faster sweepers, or to stop other Sashers from doing anything too horrible to it.
(I don't have any damage calculations, but it's fairly well-known that an endeavor from a sash always brings a non Ghost to 1%)
