If Scizor can do a good ammount of damage to Rhypereor with STAB Technician (basically a second STAB) Bullet Punch, then a 2+, STAB, Close Combat from Gallade should OKAO. And every Raikou carries HP Ice or Grass, which do a hefty ammount of damage. (I really hope the HP Fire fad doesn't come back, my wall for Raikou is Regice.
but if he comes in, SDs then attacks he's going to die before getting anything off. my point was that they can't come in on him to keep him in check, that's why I said they're just pokemon he can't set up on
+1 Raikou vs Max / Min Rhyperior:
493 Atk vs 156 Def & 434 HP (70 Base Power): 474 - 561 (109.22% - 129.26%) Clean OHKO
+2 Life Orb Gallade vs Max / Min Rhyperior:
766 Atk vs 296 Def & 434 HP (120 Base Power): 649 - 765 (149.54% - 176.27%) Clean OHKO
Rhyperior is just another Pokemon that they can destroy in a sweep to them. Plus if Reflect is up, or Rhyperior is burned, they won't have an issue boosting once.
again, these are both boosted, which is impossible if you're switching in to rhyperior or even if you both come in at the same time. Also, you're calcs don't account for Solid Rock, + 2 Gallade still kos but Raikou doesn't
Also, the reflect or burned argument is pretty dumb, since if raikou is frozen or even paralyzed it has no shot of beating rhyperior, same applies to Gallade.
Also, consider the fact that you can get Free Spikes via Froslass (1-2 Layers seems fair):
Unboosted Life Orb Close Combat vs Rhyperior:
383 Atk vs 296 Def & 434 HP (120 Base Power): 325 - 384 (74.88% - 88.48%) 81.18% average + 12.5% due to spikes + 6.25% due to SR = basically 100% (like 99.9%).
Unboosted Life Orb Hidden Power Grass vs Rhyperior:
329 Atk vs 156 Def & 434 HP (70 Base Power): 414 - 489 (95.39% - 112.67%) Clean OHKO with just SR...
329 Atk vs 156 Def & 434 HP (70 Base Power): 321 - 378 (73.96% - 87.10%) 2 layers of spikes = OHKO. Or just after Substitute.
The main point is, they both OHKO Rhyperior with just one boost, and OHKO without it.
Milotic is another huge factor that I forgot to mention. So is Venusaur.
Seeing as my lead prevents spikes and usually kos it (even though it was made BEFORE froslass came back, stop complaining that every lead that beats froslass is specialized) and I usually pack a spinner, the spikes are out. You also forgot to add in Solid Rock on these Calcs as well.
Gallade's LO CC on 434 296 Rhyperior: 68.43% - 80.88%
Standard (116 evs taken from the analysis) Raikou's HP Grass vs Rhyperior (Raikou never packs LO and rarely max SpA): 70.51% - 82.95%
Standard Raikou's HP Ice vs the same Rhyperior: 35.25% - 41.47%.
neither of them can come in on him, nor can they revenge kill the sweeper version. Venusaur and Milotic check him, which was my point, it's the other pokemon in UU, not those two, those two are just pokemon that he doesn't set up on.
Basically Automatic spikes unless you use a specialized lead against it which aren't bad, but lets face it they are pretty shitty compared to what you want to use. Even if you use a specialized lead, you only have 50% chance of stopping Froslass at all. Probably less....
Automatic Spikes + Spin Blocking them + taking out any opposing Pokemon with it = Support characteristic of uber.
Seeing as it doesn't get automatic spikes unless you insist on a bad lead (Yes, Froslass changed the Lead Tiers, any good new addition would do the same, if you still insist on using Uxie as your only lead, never adapting to froslass, it's going to set up on you all day. Also, stop talking down the leads that actually beat Froslass, Ambipom and Floatzel will win against 90% of Froslasses, the other 10% is a coin toss, and they don't set up anything, there are probably more leads that beat Froslass too, try inventing new things
By the way, Froslass is a terrible spin blocker if you use it as a lead, seeing as it's usually near death (if it survived) and has a SR weakness, it'd come in and die before the spin (one turn of spin blocking I guess... the turn it dies). If you want to use it as a non-lead spiker, maybe it can do it (I haven't seen it yet), even then it isn't immune to ground like the other spin blockers, so it has to guess right on donphan and claydol.
EDIT: also, since I seemed to miss a good amount of debate, here are a bunch of pokemon that you can make into leads that beat froslass, while not all of them would be viable, some of them are or will be due to the shifting metagame.
I'll start with the best options:
Faster Taunters: Ambipom, Floatzel, Alakazam, Persian, Electrode
Faster Pokemon (w/o taunt, so froslass gets one layer of spikes tops): Raikou, Sceptile, Dugtrio, Swellow, Purugly
Priority Taunters: Sharpedo, Qwilfish, Muk, Mismagius, Gallade, Gardevoir, Houndoom, Skuntank, Banette, Absol, Spiritomb, Umbreon, Toxicroak
Synchronise + Toxic Orb Leads: Espeon, Alakazam, Gardevoir
Priority Users: too many to name, even skipping fake out, vacuum wave, mach punch and quick attack (outside of scrappy kangaskhan)
Scarfed Sleep leads: Venusaur, Tangrowth, Jumpluff, Victrebel, Exegutor,
jumpluff can force a speed tie w/o scarf if need be
Scarfed Pokemon with base 50 Spe and a decent attack stat: A lot
are all these going to be viable leads? no, but you can definitely find some that are very viable. That's how metagames develop, Uxie, Mesprit and Regirock weren't made specifically to be good leads, they were good because they could set up and beat the other leads, which they don't do as well anymore, look through some other pokemon, they might be good in the new metagame, especially if they were weak to the leads that are losing out and strong against the newer leads
