Dropping my survey answers here as well:
Enjoyment: 4/10
Competitiveness: 2/10
I overall still somewhat enjoy laddering and I think there it's still enjoyable to stack offensive threats together trying to wear down mutual checks, even by using some funny tera sets or just trying to be more conservative and abusing hazards + phazers like Ting Lu. I do really think that the tier is a mess though, I've always though Tera is incredibly uncompetitive and I think that we have too many mons in the tier that should be Ubers. Even by making correct plays throughout whole games with decent teams, I sometimes end up getting reverse swept by Gambit/Bolt or some teams really just struggle against Tera Setuppers and you often are not able to scout those sets properly, on threats like Dnite, RM and Valiant; making the experience really frustrating and kinda forcing you into running the same type of structures with very strong Prios, hoping the oppo won't have the right tera for them, or running Red Cards and Phazers, hoping to not get OHKO'd by a creative Tera set or even Taunted. I overall still do believe that SV has great qualities, with interesting mons like the booster setuppers, Meowscarada with Flower Trick, Garganacl and Gholdengo having innovative abilities etc, but it's far from being a tier that I would be enjoying playing and I also wouldn't be able to pick one mon to get suspect tested, Kyurem might be the easiest one but it already got suspect tested twice and it survived, but as some people has been pointing out, banning a supposedly oppressive mon like Zamazenta would lead up to mons like Kingambit being even stronger, and banning Kingambit would lead to Gholdengo being stronger, so I really think the solution wouldn't be a single ban but a little banwave.
Kingambit: 5/5
I think that a well-played Kingambit will always able to reverse sweep a game if you get turns right, something that might not happen very often as you still need to get those turns right, but even when you don't you still can comeback a lot of bad situations, and having a mon that is capable of doing so is crazy to me. It could be fine without Tera, but with the access to different viable Tera's like Ghost, Fire, Fairy with Tera Blast, or Dark to boost its damages, it's incredibly hard to play against, especially with Tera Blast Fairy being incredibly hard to scout as you risk it just setupping again on your sack/pivot that is trying to scout, Tera Dark simply killing everything after an SD, and Tera Ghost + Lefties recovering so much HP that it reminds me of SS Heatran, I really fail to understand how people can be fine with this mon in the tier.
Kyurem: 5/5
If Kingambit benefits a lot from Tera, Kyurem manages to abuse it even in a better way. Kyurem already is a great mon able to trade into most of stuff thanks to its bulk and attack, but tera helps DD/Mixed sets even more, with you being able to run different Tera Blast to pick the coverage you like with stuff like Tera Blast Ghost, Fire, Ground, Electric all giving you important tools to break the few mons that can try to stop it. Speaking of scouting tera abusers, this mon is just hard to know what it will run sometimes and giving it a free turn of setup can be deadly; besides the Specs Kyurem structures with a pivot + Glowking, it can often be HDB, AV, SubTect, Mixed, DD + Tera Blast, DD + Mixed are all great sets that will either deal an incredible amount of damage or setup and threatening to win on spot, with some of the more decent checks being Scarf/Balloon Gholdengo and Booster Encore Valiant, as soft checks like Moltres really just risk dying to Rock Slide, or other mons trying to scout a special set like Glowking, risk giving a DD into another DD or just dying to stuff like Tera Blast Ground or Ghost, which also will make them very hard to kill and will most likely force a Tera and most likely still manage to get the second kill anyways.
Ogerpon-W: 5/5
Waterpon is not really a notorious Tera abuser, but it still has all what it needs to be an incredibly centralizing and strong mon in my opinion. Having a 120BP contact-less STAB with no drawbacks that has high crit ratio is just illegal, considering it has a nice bulk being able to take pretty much all x1 hits without any problem, and a very great speed tiers, let alone not having any switch-in cause you are able to Play Rough the Dragons, Knock-Off or U-turn the few viable Grass-types in the tier, while still being able to up Spikes yourself. Besides all of that, it can even setup with Swords Dance and even Trailblaze on some sets, while Tera will give it +1 SpDef to top on it, and if it wasn't enough, it even has a STAB Horn Leech and can opt for reliable recovery in Synthesis in other sets. As if having Horn Leech and Trailblaze wasn't enough to guess in-between, it also has Power Whip which has 144BP + STAB and will just deal incredible damages. It also doesn't fail to procure utility, it has the aforementioned U-Turn and also Taunt + Encore, with Encore being a very important move this gen and Taunt still being able to annoy some defensive mons, deny webs from Araquanid, or not risking setup from mons like Kyurem or Dragonite. I might agree with the thought of it being the less-broken between the choices given here, and if possible I would probably have given it a 4.5, but I definetely think this mon is absurd.
Zamazenta: 5/5
Zamazenta somehow manages to have all the most annoying perks of the 3 above-mentioned mons, being able to reverse-sweep entire endgame, being a very strong Tera Abuser with plenty of viable options, having its decent utility in Roaring out a lot of threats and moreso Booster mons, saving you from getting swept by mons like Dragonite. The Tera pool is usually Dark, Steel, Fire, Stellar, but it can always try to run other Tera's to boost its moves or to help setup against the relatively recent high usage of Pecharunt. It can even run some less-explored options like Howl, or boosting items like Choice Band and LO which is more common on Grassy Terrain, but Muscle Band and Expert Belt have seen usage as well. With IDBP you basically threat 90% of the meta bar the 3-4 Ghost mons that still have to fear Crunch with a great 20% to drop or being able to get boosted with Tera Dark, and if against the other mons you usually can counter-tera, teraing against Zama and becoming vulnerable to Body Press is often a terrible idea. Let alone that Zamazenta can also run stuff like Sub + Tera Steel to annoy BP-resists like Glowking and Gholdengo, while also being able of forcing scenario's to trade said mons just to then reveal Resto+Chesto. Really terrible to face no matter what you run, it always could have that 1 annoying tera and get that 1 timed drop to fuck you up. Very hard to check and ID boosts its defenses while making its STAB stronger, while having basically unlimited Coverage with options like Ice Fang, Heavy Slam/Iron Head, Crunch, Psychic Fangs, Wild Charge. The only positive thing that this mon does is supposedly checking Kingambit, but I really think they both just deserve a ban.
Raging Bolt: 5/5
Malding Bolt is similar to Kingambit, he will get less opportunities to setup and win as it usually runs Booster, but thanks to Booster he also often will only need 1 setup turn, which isn't hard to get on a team with great teammates and thanks to its bulk + typing, the same bulk which will make so that you don't even to risk Thunderclap "5050s" sometimes and is an amazing tool to force trades on offensive teams. Besides being an amazing endgame setup sweeper and a good tool on offensive teams to force progress on mons like Ting-Lu, it also can run sets like Specs or Boots. The higher speed tier and the access to stabs like DMeteor is what makes me not think less of him than a Kingambit. The speedtier means you can comfortably beat Kingambit in a 1v1, and having Draco Meteor and Volt Switch makes Choice Specs incredibly hard to play against as it will always force good progress no matter what. Sets like HDB still hit incredibly hard while keeping the option of having Thunderclap, but it also can run a helpful Taunt, which can be great to avoid recovery of mons like Clodsire, hazards from mons like Ting-Lu, situational occassions like a Moltres trying to Tera + Roar you out, or preventing Glowking from pivotting. Tera's aren't as explored on him as he really only needs to prevent those Ground and Dragon weaknesses usually, so Fairy is the most Popular with Bug, Flying, Ghost, Fire also being fairly common.
Gliscor: 5/5
Gliscor is yet another setupper that can use different tera's and provide different type of utilities. SD sets pretty much cook stall with their best answer being often their own Gliscor, as you can pp-stall Steel Birds and Knock Off Unawares, but also BO and balance teams really struggle with their counterplay to Gliscor, as the ice coverage isn't common and Encore users can slowly waste their pp's. It can run Tera's to boost its attacks like Tera Dark and Normal, but also defensive tera's like Water and Fairy to become incredibly hard to kill, although those are more common on its utility sets. Gliscor is of course a great Knock Off absorber, a status absorber, a great Ground Type and also a strong Ground-Immune mon that isn't much scared of hazards. It can run Spikes, Stealth Rock, even Toxic Spikes and it can also be a great Pivot with u-Turn while offering utility in Toxic and Knock-Off, being able to Toxic stall a lot of mons thanks to Protect + Poison Heal, while also having the possibility to run SubTect + Toxic. In those last months this mon has felt less oppressing as the meta has been more offensive and BO teams have been using Pecharunt which is annoying enough for Gliscor, so in general I believe it's the most fine between the 6 mons, but we must not forget what this mon is capable of doing.
Tera Blast: 1/5
I can understand why people want Tera Blast banned, it gives your opponent the perfect coverage they wish with a whole STAB move, and it makes mons like Kyurem and Valiant even scarier. I don't think it's the major issue here though, I will always be of the opinion that Tera is the bigger issue that allows all of those minor-issues and also I think that if those mons that I voted 5/5 on would get banned, Tera Blast would be left with 2 or 3 abusers, which already have incredible coverage available (see Iron Moth and Iron Valiant) and the major issue being probably Dragonite. But as I believe Tera is the issue, I don't see myself supporting or believing a Tera Blast would solve major issues.
Other mentions:
Tera: As I mentioned a couple of times, I really think Tera is what makes me not like this tier or find it really competitive
Gholdengo: Gholdengo is another incredible threat capable of doing whatever he wants thanks to all the sets he can run with 6-7 viable items and strong moves, with an amazing type and an ability that is incredibly broken.
Pecharunt: I don't believe Pecharunt is banworthy, I specified Poison Puppeteer as that move is pretty much a huge gamble that often ends up changing games 50% of the times, not sure if a complex ban of the move would ever be on the table but I already think the likes of Static and Flame Body are laughable in a competitive environment, let alone this amazing move.
Samurott-Hisui: While not being nearly as strong and popular as the mons in the survey, I think this mon is too underrated as it gets Spikes up while killing Mons and having a great typing that allows it to get a lot of switch-ins and chances in the meta.
