Just added a few to your list. Reason behind them:
Predictions:
Definitely not meant for UU: Raikou, Gallade, Regis, Milotic, Spiritomb, Shaymin, Mismagius, Abomasnow, Slowbro/king, Smeargle, Mesprit, Magmortar, Blaziken, Uxie, Dusclops, Slaking, Umbreon, Porygon 2, Tangrowth, Honchkrow, Staraptor, Crobat, Azumarill, Pinsir, Sceptile, Roserade.
* Uxie -- Yawn + U-Turn + Stealth Rock + Screens + Great Walling Ability
* Dusclops -- It's same with Spiritomb basically.
* Slaking -- CB Slaking = FPS Doug's Boom Headshot
* Umbreon -- Look at its base HP/Defenses and its ability to Mean Look, Sub, Yawn and Baton Pass to almost anything or Wish heal teams.
* Porygon 2 -- Self Explanatory. If it can jolly rogers stop Heatran/Magnezone, then it can cripple a lot of shit like Magneton, Ninetales, Arcanine, etc. A lot of other reasons as well, but if you have ever used him, you should know what I'm talking about.
* Tangrowth -- Fast Powders, STAB Power Whip, very nice Physical Wall + Synthesis, Specially Available as well. Very versatile.
* Honchkrow -- Very offensively versatile, both Physical & Special; on top of that, STAB Sucker Punch dents shit in UU, while special attacks can kill steels such as Heat Wave.
* Staraptor -- Brave Bird + Close Combat + Intimidate + Great Attack & Speed... It's pretty much obvious.
* Crobat -- Fastest sleeper & taunter, can deal great damage, U-Turn available, can Plot if he needs. Shuts a lot of UU down with taunt, can Roost, early game Weather set-upper.
* Azumarill -- Huge Powah. Enough said. 436 Attack is nothing to joke about in UU, especially Super Effective Waterfall on Steelix with STAB. Encore available if used as annoyer.
* Pinsir -- What in UU can wall this shit? Earthquake + Close Combat + X-Scissor + Stone Edge covers basically everything. Levitaters can't even get away from Earthquake. Weezing = Earthquake says hi.
* Sceptile -- Speed + Offense, BOTH offenses... It can sweep UU easily, if not, wear it down overtime, and switch if a counter is pulled up. I don't think currently there's any UU that can match his speed besides Electrode, who can't do shit without HP or explode itself.
* Roserade -- This thing was OU at once for a reason. Sleep Power + Toxic Spikes + 125 Base SPA STAB Seed Flare. Can rip UU once other BL suspects are removed.
