Stop using this title format to draw in viewers (it is bad and obvious, the content of your post should be enough to carry it) Haven't made a post in a while, would like to share my thoughts on some stuff.
I'm sorry, how exactly was this quickbanned and implied to be as broken as Great Tusk (ultra broken mon) and Baxicalibur (personally I thought it was manageable but I get why people thought it was broken) in the same breath? You are actively handicapping yourself if you put Houndstone on a team because you are committing to playing a 5v6 for the whole match. Of course some offensive mons are gonna have bad MUs and you'll be playing a 5v6 regardless sometimes, but with Houndstone it happens in every match because it is obviously your win condition. Because Houndstone only works in 5v6 scenario, it doesn't really get the chance to wear down its own checks and instead has to heavily rely on teammates to do it. Compare that to something like, say, any other breaker in the tier that can come it and use a powerful move to force a predictable reaction. Houndstone can't do that because Last Respects only becomes usable when you're down by 3 mons, which is often too late in the game to position your Houndstone correctly for more than one chance to sweep.
A lot of what the ban reasoning conveniently glosses over is that Scarf Houndstone has a really bad Speed tier for a Scarfed mon. 385 if Jolly (the only good set, please do not use Adamant it is so bad) is outsped by Talonflame, Chien-Pao, and various Scarfers such as Armarouge, Mewoscarda, Roaring Moon, Sandy Shocks, and Greninja. None of these individually are the most common mons, but together these can be reasonably put on any viable team for little opportunity cost, as well as the fact they are just generally good at dealing with offense. Houndstone running SE means that it is picked off by any priority, from Sucker Punch Cinderace to Triage Hatterene to Aerilate Dragonite. Priority is very common on teams right now due to how powerful the mons with priority are to begin with, meaning that most competent teams contain some form of offensive Houndstone counterplay.
As for the point about there only being binary checks to Hounstone, this would be true...if these checks were uncommon or even difficult to fit. It's not something like Noivern where it could be stopped, but doing so required one of 2 mons (Blissey, SS Garg) that were mainly used for Noivern (excluding the fact that Noivern could run Super Fang + Taunt to shit all over its switch-ins); all of Houndstone's defensive and offensive counterplay are easy to fit and should naturally be on almost every viable team. Kingambit and Roaring Moon were already pretty good before the Great Tusk ban, but now with it gone, they should easily rise in usage; Ting-Lu is a bit more iffy imo since it directly competes with the other 2 Dark-types for a Regen slot but its stocks are going up as well. In fact, the Great Tusk ban would have made things worse for Houndstone, since now there's a lot smaller of an opportunity cost to running both defensive and offensive Dark- and Normal-types, both of which directly check Houndstone.
As I said at the beginning, I really am struggling to see what exactly caused this to be quickbanned, let alone 6-0 quickbanned. It was B-tier for a reason: very little usage (10% or less every round), and when it did show up, it had a horrible win rate (under 40% every week in the AAA money tour). I really do think the council should have provided some replays for this mon considering there was no discussion surrounding it leading up to the ban. I guess one upside to banning Houndstone is that it leaving really doesn't impact the meta negatively but that's not a mindset we should have when tiering. I would really like to see the ban reversed considering I don't really how this could possible be construed as broken.
Coming back to Shed Tail real quick, I would just like to say that the bans that have taken place have done nothing to limit the absurdity of the playstyle. You can just replace Bax with SD Chien-Pao/SS Cloyster; although there are obvious downsides, the playstyle performs more or less the same, still autowinning games because your counter to Polteageist can't actually do anything to it behind a Sub, or you gave Orth a single free turn and now you are screwed. I don't see a reason to keep this around, it's fun to abuse but I am straight-up tired of auto-losing because I did not play perfectly around Orth and friends, and it takes the game out of the player's hands. I still think that Orth is the main issue considering fast Shed Tail is much worse than slow Shed Tail + Orth has great physical bulk that lets it get up a Shed Tail in the first place, but I'm perfectly fine with just nuking the move as a whole.
It is time. The Great Tusks have fallen. Corvid, overwhelmed by Stealth Rock and GaG mons, desperately needs assistance. Hazards are omnipresent, moreso than any other point in Gen 9 AAA. The Magic Bouncers will rise again!
In all seriousness, I still believe that both Magic Bounce bans in last gen and this gen were grave mistakes. Last gen it solved like one problem that wasn't even that serious imo and failed to address the 200 other problems with the tier, because the 20+ equally viable breakers that rose the power level of the tier to an unmanageable amount sure was balanced am I right guys? I don't think I even saw any broken applications of it this gen before it was yeeted in the same slate that POISON HEAL was, it felt premature and only really done because it was banned last gen. SAC makes double Regen cores unfeasible so one of the main ways of abusing MB suddenly does not exist. The other main MB abusers, Screen setters, were all heavily nerfed since none of them get Taunt (or at least none as fast as Tapu Koko get Taunt), and GaG is able to deny a majority of the Screens counterplay (Defog, fast Taunts) about as well as MB did. Being able to get hazards up vs Screens setters now is obviously a big difference but considering all the 2x weak/4x weak/Sash mons in the tier are either nerfed (Zard), can run Boots (Pao), are better on Shed Tail (Polt), or just straight up don't care (Bax before it got banned), I wouldn't classify this as a big enough change to keep MB banned. Overall I think there's a case for this to be reintroduced back, and I would like to see a suspect on it. (also I really wanna use Table Stall again and not have to use shit like Bramblegoat to win)
I'm not saying we should unban Magnet Pull...BUT
IWON WEAVES 
so this won't work
it doesn’t mean you can’t handle it but you’re forced to run suboptimal sets like idef corv, who as I mentionned can lose to coverage moves/if it’s paralyzed, or Queenly Majesty mons (that still need corviknight to slowly pivot bc you can get hit on the switch, so you take the risk to be slower and die on Dragonite’s coverage move)
