You are not answering my argument. I already cut that argument off at the head and agreed that Kyurem-B does murk stall. It was almost suspected at the end of Black/White 2 for a reason. It is a threat. However, I think these rankings should be based on the ability to be plugged into a team easily and work.
Okay Kyurem-B still murks stall, but doesn't Charizard-X, Charizard-Y, Mega Heracross, etc, do it even better? That's debatable, but my point is it has competition. My argument for dropping Kyurem-B is not to say it is not effective at destroying stall because it is, but you cannot plug it into a team easily. I'm sorry. Lets look at what kyurem-b can switch into on the usage statistics...
#1 Rotom-W, volt switch or WoW, however, sub versions can switch into Hydro and sub. (Requires a lot of prediction which should not be factored into usage stats because these are supposed to be "easy" to use)
#2 Talonflame, with rocks BB 2hko's and it can u-turn
#3 Lucario lol not switching in on this
#4 Genesect UTurns or hits it with Iron Head...
#5 Aegislash Flash Cannon kills after rocks
#6 Heatran Its not switching in on a lava plume even if its got earthpower
#7 Garchomp, its slower otherwise it can switch in on an SD
#8 Greninja uturn
#9 Scizor not switching in
#10 Excadrill not switching in
Do you see my point? It can't safely switch into any of the top 10 pokemon without some serious prediction skill. How is that a pokemon that deserves A-rank. There are tons of good stall breakers. The difference is those other ones, in my opinion, are much easier to use.
Yes Kyurem-B is a powerhouse, and yes it recks stall, but its too slow to switch into most offensive pokemon, and its weak to rock, steel, fighting, fairy, and dragon. Please, don't say something like "well zard is weak to rock" Charizard is also immune to earthquake and easily switches in on heatran, genesect, scizor, Zard-X can come in on Rotom. My main point is that kyurem-b is outclassed by other stall breakers with ease of use such as charizard.
Alright, you can say it isn't easy to plug into a team all you want, you're wrong. You telling me who the top ten in usage statistics are doesn't mean anything. My opponent's Pokemon don't have anything to do with my team. How he matches up against the other team is a different story, but good luck having a team of the top 6 and expecting a flawless team. Speaking of the top six, you're arguing under the notion that Kyurem-B is supposed to be a counter to everything. Talonflame can't switch into Rotom-W, guess it better be B rank, right? No one ever claimed Kyurem-B to be a counter to any of these. That's not his job to counter anything. He's weak to common attacking types and that's the reason he's in OU coupled with his speed. Once Kyurem is
safely in, look what he can do (these are all the usage sets considering you're so keen on usage)-
#1:
252+ Atk Teravolt Kyurem-B Outrage vs. 252 HP / 0 Def Rotom-W: 249-294 (81.9 - 96.7%) -- guaranteed 2HKO after Leftovers recovery
You stay into burn and you're dead. Stay in to Volt Switch and you're probably dead.
#2:
252+ Atk Teravolt Kyurem-B Fusion Bolt vs. 4 HP / 0 Def Talonflame: 388-458 (130.2 - 153.6%) -- guaranteed OHKO
252+ Atk Teravolt Kyurem-B Outrage vs. 4 HP / 0 Def Talonflame: 348-411 (116.7 - 137.9%) -- guaranteed OHKO
If he's already in and above ~60% he doesn't care how fast you are.
#3:
I'll give you this, but seriously who expects anything to threaten Lucario at this point, he's S rank for a reason
#4:
252+ Atk Teravolt Kyurem-B Fusion Bolt vs. 0 HP / 0- Def Genesect: 170-201 (60 - 71%) -- guaranteed 2HKO
4 Atk Genesect Iron Head vs. 4 HP / 0 Def Kyurem-B: 204-240 (52 - 61.2%) -- 94.9% chance to 2HKO after Leftovers recovery
He can Iron Head all he wants, and in reality Genesect is probably Choice locked in the first place. Him U-Turning is a bullcrap argument because that's what U-Turn is supposed to do, give you the upper hand. I can yell at you all I want that I can U-Turn out of something into a counter. That's U-Turn's job.
#5:
Previous post because I already made the point here. It's really a stalemate between the two and Aegislash probably wins through mindgames. But it isn't any Dragon's job to kill a Steel type, now is it?
#6:
252+ Atk Teravolt Kyurem-B Fusion Bolt vs. 252 HP / 0 Def Heatran: 140-165 (36.2 - 42.7%) -- 95.8% chance to 3HKO after Leftovers recovery
4 SpA Heatran Lava Plume vs. 4 HP / 0 SpD Kyurem-B: 118-141 (30.1 - 35.9%) -- guaranteed 4HKO after Leftovers recovery
He can actually beat this Steel. Offensive Heatran loses the bulk it needs to beat Kyurem-B.
#7:
252 Atk Garchomp Outrage vs. 4 HP / 0 Def Kyurem-B: 392-464 (100 - 118.3%) -- guaranteed OHKO
Okay, now Garchomp is locked into Outrage and you can easily revenge kill it. It still ends up being a high risk situation for the opponent.
#8:
252+ Atk Teravolt Kyurem-B Dragon Claw vs. 4 HP / 0 Def Greninja: 244-288 (85.3 - 100.6%) -- 6.3% chance to OHKO
That's just Dragon Claw. You saying U-Turn is once again weak. He's slow, we know.
#9:
Another one I'll give you, but again, the whole point Kyurem-B is allowed in OU is that he's weak to common priority and attacking types.
#10:
252+ Atk Teravolt Kyurem-B Outrage vs. 4 HP / 0 Def Excadrill: 199-234 (54.9 - 64.6%) -- guaranteed 2HKO
252+ Atk Mold Breaker Excadrill Iron Head vs. 4 HP / 0 Def Kyurem-B: 296-350 (75.5 - 89.2%) -- guaranteed 2HKO after Leftovers recovery
Cube outspeeds and wins.
It's also extremely unfair to assume either side will always be at full health, because Cube is just a nuke. He's doing ~50% to Steels with Outrage (with leftovers) so when they switch in they're losing so much health that he can sometimes afford to switch in. Not really sure what you're trying to prove with Charizard-X, considering they both are weak to common attacking types but Charizard is weaker, frailer, albeit faster. In fact, I can argue all I want all your points can also easily apply to Charizard-X so he should be B-Rank too. All the things you said he can come in on can use the same argument, they'll just U-Turn or Volt Switch out and Cube can in fact come in on Heatran. You're not using Cube in the right context (if you've ever even used him at all)/ No one is or ever will claim these guys counter anything because that's not their job. No one is telling you Talonflame sucks because it doesn't hard counter Tyranitar and Rotom-W. That's not their job, don't act like it's their job. His job is to leave huge dents in anything that tries to touch it and that's exactly what he does.
