One important point you keep missing d2m is that simply because Raikou is open to revenge killing doesn't mean it gets revenged killed. In fact more often than not Raikou will go out to an answer for what you are attempting to revenge kill with, and then come back in later. You keep repeating that weathering down counters is an argument fit for any sweeper, but the same thing holds true for allow a kill and then revenge kill. Garchomp could be revenged by Froslass, or if low enough aqua jet from Azu, but you certainly aren't arguing that Garchomp wouldn't be broken in UU.
The whole well your argument applies to any pokemon thing can be applied to almost any argument, the difference between pokes being the degree of truth. Yes a Nasty Plot Pikachu could sweep if all its counters were gone, but that is a much more daunting task than removing Raikou counters who number far less and are much less a certain thing. That is the difference, what few things stop Raikou are too easily weakened to a point that they no longer wall.
I'm not saying Revenge killing is the only reason it's not BL. What I'm saying is that its only chance to meet the offensive characteristic is for it to be able to set up. Then I go on to say that Stall has Registeel, Chansey, and Clefable among others that can halt it's setup by threatening it and sponging it's hits. I say after that that offense can easily sac whatever weakened sweeper they have out at the moment to prevent setup, then switch to something more threatening. It's still technically a "revenge kill" but it completely prevents setup.
Without setup, Raikou's 1 and only set is defeated.
Edit: Let's draw a comparison with recently voted BL Yanmega. Yanmega was BL under the offensive condition because the Specs/Tinted Lens set could come in on anything that was slower (a significant portion) and didn't carry a strong enough priority attack to do 50% (i.e. Not Honchkrow) then proceed to 2HKO damn near the entire tier as well as landing a huge hit on whatever actual counter you did switch in.
Raikou, on the other hand, is only that threatening if he gets a sub up on the switch which blocks Status, 1 attempt at a revenge kill, and guarantees at least 1 boost. The only way he can get a sub up is if he is able to reliably switch in to a vast majority of the tier and set up against all styles of teams, instead of being instantly threatening like Yanmega. I have shown through all my posts that both styles of teams have myriads of options in preventing said setup. While it can occur and he is extremely threatening if allowed to set up, he is not BL in the way Yanmega was because he cannot reach the Offensive Condition under anything but extraordinary circumstances (i.e. actually getting +1 behind a sub).
AKA: You couldn't think of a counter-argument. No one has argued these points with me. When Lemmiwinks and/or BnE decide to do so, there might be a valid argument on the table for "Raikou is UU". Unfortunately for Raikou you can't seem to do justice.
Read the gigantic compendium thread and Lemmi and BnE's posts about spinners from earlier. You're under the mistaken impression that saying something a bunch of times in a row makes it true.
Flawed logic. How about I'll list all the semi-offensive Pokemon Raikou can set up a Substitute or Calm Mind against via forcing out/ease of setting up Calm Mind. These are using "standard sets". So Blastoise doesn't have Earthquake etc.
Note: these ARENT Hidden Power based at all. I'm pretty well only using Thunderbolt, Substitute, and Calm Mind here.
Blastoise (Goes first and can set up a sub after a CM. Threatens with STAB Tbolt as well.)
Drifblim (Can Calm Mind up and set up a sub and threatens with Tbolt)
Espeon (Can Calm Mind first and beat it. Though, SpecsEspeon can make it really difficult for Raikou to set up)
Froslass (it can set up one before Taunt)
Houndoom (Goes first and can set up a sub after a CM.)
Lanturn (Goes first and can sub "reliably" after a CM (it can possibly get a sub up before that)
Magneton (resists Magneton's STABs and goes first + sets up Sub after a CM)
Mesprit (Goes first and sets up a sub after CM)
Milotic (Goes first and sets up a sub after CM. Also threatens with Stab Tbolt)
Mismagius (Goes first and sets up a sub after CM)
Moltres (Goes first and sets up a sub after CM and threatens with STAB Tbolt)
Omastar (Goes first and sets up a sub after CM and threatens with STAB Tbolt)
Rotom (Goes first and sets up a sub after CM)
Sceptile (Either on the revenge kill, or if Sceptile is locked into an attack, Raikou sets up a sub after a CM)
Scyther (Goes first, can set up a Calm Mind on a resisted Aerial Ace or Brick Break at worst, and easily OHKO at any time with Tbolt)
Slowbro (Goes first and sets up a sub after CM, also threatens with STAB tbolt)
Spiritomb (Goes first and sets up a sub after CM)
Typhlosion (With Stealth Rock, Eruption won't hurt much, but it wouldn't be crazy if you argued that this wasn't on the list).
Uxie (can't break Sub at all)
Weezing (can't break Sub, never mind after a CM)
ALL of these Pokemon are forced out or are Calm Mind bait. Before you even think of saying "But they can Sac themselves to stop Raikou like wtf", actually think about it (for once). If these Pokemon don't switch out, Raikou can and will set up Calm Minds against them. They are almost always better off switching out than flat out losing to Calm Mind Raikou via letting it set up. If they stay in, then +6 Raikou actually has zero counters.
My argument is thus: Raikou cannot set up a substitute against nearly any decent offensive threat in the tier. Thus he cannot establish a position with which to sweep with little effort, thus he is not BL. Let me rework your list for you.
Bold- Raikou can set up on an offensive set.
Italics- Heavily dependent on set and situation, but it is possible he could set up.
Normal- Incorrect.
Blastoise- Offensive set easily breaks subs with Surf, Scarf set (becoming increasingly popular) does major damage with Water Spout.
Drifblim - Shadow Balls break subs up to +2, not to mention Unburden makes him outspeed and (at least mine) always ran D-bond for the end unburden kill.
Espeon - Specs Espeon can make it really difficult for Raikou to set up and even if Raikou beats a Sub/CM set eventually, it won't do so with a sub out.
Froslass - Assuming Froslass is an offensive threat is assuming it's on a Hail team and Blizzard easily breaks subs and does significant damage even if it CMs once.
Houndoom - Largely depends on set. NP Mixdoom (my favorite set) plays mind games with Sucker Punch and Fire Blast. The only set he'll get out of with a sub intact is a pure special set without NP, which is just a bad set.
Lanturn - assuming an offensive set (because if you read the challenge it at least qualifies as semi-offensive, so using a defensive poke with an offensive set would be the only way to put them on the list), sub is still broken by surf after +1. With a specs hydro pump it's even more.
Magneton - Depends on Hidden Power, but in all likelyhood, yes, he will set up on Magneton.
Mesprit - Only if it's a special utility set, most people nowadays run physical scarf which means she outspeeds and breaks subs with Zen Headbutt.
Milotic - Assuming offensive set (LO with at least some SpA investment), it will break +1 Subs with Surf and +2 with Hydro Pump.
Mismagius - If it's coming in on missy, it either has a boost or a sub, meaning it stats up alongside Raikou and, in the end, will at least leave Raikou without a sub if not dead depending on the amt of boosts it started with.
Moltres - Fire Blast still breaks a +1 sub.
Omastar - the only offensive Omastars I see are Specs/LO on RD teams, and a RD boosted (or just plain max SpA) Surf still breaks even +1 subs outside of rain.
Rotom - completely depends on set but I'll grant it's possible.
Sceptile - Obscenely situational and set dependent. Would go way too far into theorymon here either way.
Scyther - Easily breaks subs with near anything, especially after a SD.
Slowbro - Offensive Slowbro sets? I can only think of his own CM set where Psychic still breaks subs at the same lvl of boosts.
Spiritomb - If it's not carrying an attack stronger than Pursuit, yes, but CB pursuit still breaks subs. Still, there are offensively viable threats Raikou can set up on, I'll grant that.
Typhlosion - Really?
Uxie - Zen Headbutt or Offensive CM set easily beat Raikou's sub (the latter can beat Raikou himself if Uxie has some HP/SpD EVs)
Weezing - There's really no such thing as an offensive Weezing set, and if there was one it'd carry Explosion.
Yes there is. Ambipom ties at best. Foe Mismagius (don't act like this isn't important), Scyther, Quick Feet Ursaring are all out sped. In addition Espeon and Froslass (hugely important). Keep in mind, this is the "not as important" aspect of why Raikou is better than Missy (and basically all other sweepers). It also threatens out so many more Pokemon (look at the list above).
Playing a 50/50 speed tie on Ambipom and Scyther isn't much special, Froslass is largely irrelevant, and QF Ursaring can't survive against an HP Fighting Missy.
While you can argue all day that Missy's immunities are better than Raikou's defenses, you are flat out missing the point. Raikou is BULKY. It will set up Calm Minds and substitute on Pokemon that Missy can only dream of (look at the list above...). Raikou also only has one weakness, and there is no priority Ground attack. Missy is easily revenge kill-able by anything with any sort of Ghost or Dark priority (Gallade ring a bell?). Physical defense is also important in general, and while Raikou has nothing to phone home about, Missy's defense is pathetic. It is beaten by Azumarill, who can't even manage 50% on most Raikou.
Immunities are important for switch-in power, but the lack of weakness, and just defenses in general are much more important than immunities for a Calm Mind sweeper.
Shadow Sneak is used by 2 Pokemon with any regularity: Gallade and Spiritomb. Gallade is easily OHKO'd by any sort of boosted Shadow Ball, and Spiritomb is well-recognized as a Missy counter along with Registeel.
You are using that word very loosely in the bolded area. You also failed to do the last step :(
The fact I've repeatedly shown you're either warping my argument then arguing against it (see list) or just plain ignoring my argument and making your own logic is good enough for me.
