Metagame 1v1

I would make a big huge post discussing my opinions. Thing is, I already did that back in August. So I'm just gonna re-link my old Kyurem-Ban post. While some info may be outdated, I think the point it's trying to make still stands.

http://www.smogon.com/forums/threads/1v1-kyurem-black-suspect-test.3587523/page-23#post-7473432

Also, concerning DEG's thoughts on the Kyurem-less meta, I personally believe that it's a whole lot better. With Kyurem-Black gone, you can spend more time preparing for the rest of the metagame, which includes Sturdy users. Yes, they have certainly gotten more common, but I feel that it still isn't unbeatable. But if Kyurem-Black is banned, and it really turns out that the Sturdies become too much (which they won't, trust me), just suspect them! Remember, we don't wanna check broken with broken.
Oof I still haven't updated that spreadsheet
 
You don't mind if I... borrow this post for a bit and change some things, do you? No? Thanks.


Personally, I don't see this suspect as trying to determine if Aegislash is broken, anyone competent knows that it isn't. I see this more as the community making a choice as to which kind of XY OU metagame they want, since XY OU with Aegislash is very different from XY OU without it. For example, in the meta without it, there would end up being things that rise to Genesect levels of overcentralization, thus requiring further bans and/or suspect tests despite the fact that they never would have even been considered suspect-worthy in a meta with Aegislash allowed, however, this doesn't mean the meta would be objectively bad, just different from what we're used to. Here's a bit of a quick outline as to what the two kinds of metagames would be, from what I know of XY OU, based on the results of this suspect test.

Aegislash is banned
  • All mons previously threatened by Aegislash get a boost in usage, and a lot more freedom in using their movesets, particularly Tyranitar and Heracross
  • Latios becomes the new "top" of the meta, in terms of how many potential sets you have to choose from all in one mon
  • Mega-Gardevoir no longer has a top usage mon keeping it from being broken/overcentralizing
  • The three best mons in the metagame (Latios, Heatran, Mega-Pinsir) lock into a triangular relationship
  • New potential viable sets get to rise with the meta's minimum power curve dropping
  • Dark types lose even more of their dominance over the metagame
  • Overall diversity is increased massively, leading to an even less consistent metagame

Aegislash is not banned
  • Dark types continue to rise, using Aegislash as their main reason for being viable
  • Metagame continues to be based around Aegislash, due to Aegislash's King's Shield being the most common move people have to play around
  • More potentially broken mons could be unbanned, using the high power curve as their warrant for unban
  • Aegislash continues to force guessing games as to which set it's using, as well as whether you even beat those sets or not
  • Niche sets and mons made to counter specifically Aegislash will continue to rise in usage (Umbreon, Earthquake Latios, etc)
  • Mons that could potentially rise to cancerous levels are kept in check/hindered by Aegislash's presence
  • Metagame stagnates until Omega Ruby and Alpha Sapphire come to shake things up

I know speculating what the metagame "might" be is typically frowned upon, but that's essentially all that this suspect test is about, since Aegislash's effect on the metagame is much more significant than the actual mon itself. Regardless of whether my particular outlines come true or not, XY OU with Aegislash and XY OU without Aegislash would almost certainly be very different from each other, and it is up to us to decide which version of XY OU we believe would be the healthiest for us and newer players who would legitimately want to learn the meta.

And I know I don't, I didn't even play XY OU very often so my points may be wrong in this post (I did read the suspect thread as a quick refresher though) but this was presented to me and I had to point out the blatant flaws in this argument, and that it was made in the past with other things that ultimately ended up to be "too broken," and you probably get the idea of what I was trying to write up anyway.
And guess what, the meta was fine. And quite a few things post-Aegislash ban that were thought to be broken... never were, would you look at that!

Immediately reading this post: "anyone competent knows" gives me bad vibes, to the point that I'm thinking "...is Glyx actually serious here or am I seeing Poe's law in action?"
Let me be honest about something. Judging by what I've read by this thread, Kyurem-Black already has Marshadow levels of overcentralization. You must have a way to beat it, or else you automatically lose to it from team preview. And there are quite a few sets it can run, from gimmicky lures to the standard "SUBZERO SLAMMER X D" that can be either bulky or fast depending on what it needs to beat.
If anything, your arguments about it "keeping the metagame together" only make me think it's even more unhealthy with it. It's a metagame warped around a single Pokemon. That's essentially the textbook definition of that mon being broken, it was one of the major reasons why Aegislash was banned from XY OU, why I believed Primal Groudon and Gengarite were broken in Balanced Hackmons, etc.
I would go more indepth about this and how running more "niche" things for Kyub already shows that it's honestly broken, but... I think stuff about this has been said before and that Kyub technically has the tools to beat those too if it so desired. Aegislash and Kyub are different, but I posted this because I noticed similarities between both of the "keep X in the meta" arguments.

While I understand you are relatively skilled at 1v1 and respect your skill, I'd like to say that this is one of the worst anti-ban arguments I've seen in this thread, to the point where reading it makes me want it gone even more. And let me remind you that I don't play 1v1, so theoretically, I should have no opinion. But hey, I read the posts in this thread, I may as well have some opinion.
Uhhhhh... I'm confused. Where exactly in her post did Glyx say that she was against banning Kyurem-Black? I've read it over a few times now, and I can't find anything that even implies this. All she was doing was showing what would happen in both cases, and letting the playerbase decide which meta they prefer. Again, I can't find any line where she lets her feelings through. If anything, phrases like "Kyurem continues to force guessing games as to which set it's using, as well as whether you even beat those sets or not" and "Metagame stagnates until Ultra Sun and Ultra Moon come to shake things up" imply that she's actually pro-ban to an extent.

And now to hope I didn't say something stupid and shoot my credibility in my foot.

...oh

it was poe's law, i was just told it was a serious argument and reacted as such

you can have the gun if you still want it i'm done using it to shoot my own credibility in the foot sorry about that
at least it did its job in making me want kyub gone hahahaha whoops

Looking good, I know there's a few teams I can't wait to play. Should be fun all round!

Also let's not forget to thank sirDonovan for setting up a draft bot so this could actually happen!

PYUKUMUKUUUUUUUUUUU
 
I am not a 1v1 player whatsoever... I am really surprised I managed to get reqs, too. I wanted to write my thoughts regarding Kyurem-B because why not... please pardon me for my zero 1v1 knowledge.

I played some 1v1 games before the suspect test and the first thing I was really paranoid about while teambuilding is Kyurem-B.

Even though Kyurem-B is very versatile, every Kyurem-B set could be beaten by the right Pokémon; there's no one broken set that beats everything. However, this fact put so much pressure on me while teambuilding, if not restricted it to some extent.

During the suspect ladder without Kyurem-B, I was really satisfied with the fact I didn't need to overprepare for Kyurem-B. The fact I had so much less pressure while teambuilding made my overall building and playing experience a lot more enjoyable than with Kyurem-B on the meta.

Even though I had lots of fun messing around with Kyurem-B and its many sets before the suspect test, I have to say I enjoyed the Kyurem-B-less meta more, therefore I leaned towards voting ban.
 
I'm not really one to get heavily involved in stuff like this, but I'd like to try and convince those who have not yet voted, or those who are planning on getting reqs to vote, to not ban Kyurem-Black.

There's always been a lot of speculation about the fate of Kyurem-Black in the 1v1 metagame. It can be argued that Kyurem in the current meta has simply adapted far too well to any threat, and can pull off a set to eliminate what could be seen as any "hard counter". For example, Kyurem can utilize a few rather niche sets such as Haban Berry to lure and beat opposing Kyurem and Charizard-Mega-X, Groundium-Z can be for fat steels such as Heatran and Magearna, Roseli berry for offensive Mimikyu, Weakness Policy for Mega-Gyarados, and the list goes on.

Kyurem-Black does offer extreme versatility and can indeed put a strain on teambuilding when trying to cover for every single possible set. There's no denying that you're never going to be able to have a good team that can cover literally ever single one of Kyurem's sets. But is this really enough to warrant a ban? Versatility does not instantly account to broken, or unhealthy. While one set might beat a specific threat, it then loses to so many others. Kyurem on paper seems like its a broken mon, but in reality there's far more consequences to banning Kyurem rather than keeping it.

Kyurem is meta glue. It is the center of the metagame and as a result is extremely influential in practically every aspect of 1v1, from teambuilding (including custom spreads) to the ps ladder to tournament gameplay. Considering the current metagame and the suspect ladder, Kyurem is needed for metagame stabilization. The current metagame without Kyurem allows an extremely rapid influx of suddenly many more viable mons. To name a few, there's Golem, Donphan, Dragonite, Magnezone, Mimikyu, Tapu Koko, Landorus-Therian, Greninja, Jumpluff, Whimsicott. While a standard kyurem can't beat every mon mentioned here, its presence alone is enough to keep back a lot of mons from suddenly jumping up and becoming the new dominating figures of the metagame, notably Dragonite.

While I do believe that a suspect for Kyurem was needed, I don't believe that now is the right time for it, let alone a ban. We're barely less than a month away from ultra sun and moon, which is going to potentially introduce game changing mechanics and completely new pokemon to shake up the meta. Yet, despite being so close to a new meta, people want to ban the central figure of 1v1 and free a bunch of new threats? If this is done, the metagame won't stabilize at all before ultra sun and moon is released. We'd be leading one unstable meta into another. Banning Kyurem now doesn't make sense. I don't see the point. Keep Kyurem for now, test again down the track once the metagame has settled and stabilized to what ultra sun and moon has given us.

tl;dr = save Kyurem-Black. If there's a time to ban it, it's not now.

There are some things I do not agree with.

1. "Kyurem is meta glue". I know 1v1 works differently from standard formats, but let's take a moment to compare 1v1 Kyurem-Black to OU Landorus-Therian. Lando-T in OU is a dominant, meta-defining force due to walling a bunch of powerful physical attackers such as Kartana, Tyranitar and others while also providing excellent Rocks support and pivoting with it's Rocky Helmet set, or being able to sweep efficiently with the Double Dance Z-move set. Despite this, it has some noticeable flaws, primarily an average speed tier for OU standards, less-than-ideal special bulk, and a lack of viable recovery outside of Leftovers and Rest. Said flaws are exploitable by Pokemon such as Tapu Lele, Ash Greninja, Celesteela, Volcarona, Kyurem-Black, Mantine, Tapu Fini, and much, much more (Yes, some of these lose to Flyinium, but in 6v6, there's a thing called switching, which means that it you play properly, you can make sure Lando can't get into a situation where it can set up to begin with.) Now, how about 1v1 Kyurem-Black, which can wipe out nearly 80% of the metagame with just Scarf and Icium Z, near unwallable coverage with Subzero Slammer + Outrage + Fusion Bolt, and a crappy defensive typing being compensated for by huge bulk, which, with investment, can tank shit like Mega Mawile's Play Rough? And remember, in 1v1, you can't switch into your check/counter. You also can't wear it down with entry hazards and such.

Here's a little analogy I like to use: Let's pretend 1v1 is a playground. Mega Gyarados is the playground supervisor, who keeps some of the tougher kids like Golem, Donphan and Dragonite from getting too rowdy. Kyurem-Black, meanwhile, is the mean vice principal who hurts the bullies and the innocent kids for no reason, and who constantly gets into fights with Mega Gyarados, yet has somehow not received discipline for his behavior, which has caused all the kids on the playground to fear and despise him.

2. "USUM is coming out soon, why not wait to see what changes it brings to the table?" Referring back to OU, Arena Trap wasn't banned too long ago. It believe it was banned in the middle of September, correct? By that point, it was only a month and a half or so left until USUM. But they still suspected it. Why? Because Arena Trap was an overcentralizing force to the point where people wanted immediate action to be taken. It's a similar case with Kyurem-Black. You can speculate all you want about what the new Pokemon/move tutors/z-moves will do, but when it comes to tiering and suspects, we need to make decisions based off the CURRENT metagame, not the metagame we'll have in a month. And in the CURRENT metagame, Kyurem-Black is a highly controversial Pokemon, to the point where people on both the pro and anti ban sides felt that a suspect was in order to determine how broken it was, and what the meta would be like without it.

I think you're a little ill-informed on a couple of things.

"For example, Kyurem can utilize a few rather niche sets such as Haban Berry to lure and beat opposing Kyurem and Charizard-Mega-X, Groundium-Z can be for fat steels such as Heatran and Magearna, Roseli berry for offensive Mimikyu, Weakness Policy for Mega-Gyarados, and the list goes on."
Fun fact: Kyurem-B has such goddamned good stats it can run enough bulk to live opposing Kyub and Charizard X's Outrages without the need for Haban Berry while OHKOing them with a Banded Outrage (or Specs Draco, Subzero, etc). Heatran loses to most non-Scarfed Kyurems without needing to resort to Groundium Z. As with the dragon types, Kyurem can run a physically defensive Choice Band to tank and OHKO Mimikyu.

Secondly, you didn't mention the real reason that Kyurem is broken: unpredictability. The argument that you did touch on, in that it has next to no counters, is not to be used as a stand-alone argument. Rather, the fact that A) you can't tell what set Kyurem is at team preview, B) that its sets beat different things, C) Kyurem's niche sets see some usage (1/3 Kyurems aren't running Scarf or Icium) and D) Kyurem has only a small handful hard counters (and most of them have to run off-meta sets to truly counter it) can lead us to this conclusion: that Kyurem-B is impossible to reliably win against unless you happen to be running one of its few counters. In short: it makes you lose when you should have won unless you start running Mega Metagross or Terrakion on all of your teams, which is obviously unfair and uncompetitive.

Sorry but I honestly can't take any of that seriously. You're comparing 1v1 to OU, have you even seen how completely different these metagames are to each other? You've completely ignore the fact that role compression is a major factor in OU but practically does not exist in 1v1. The two simply aren't comparable in any way.

I think you're a little ill-informed on a couple of things.

"For example, Kyurem can utilize a few rather niche sets such as Haban Berry to lure and beat opposing Kyurem and Charizard-Mega-X, Groundium-Z can be for fat steels such as Heatran and Magearna, Roseli berry for offensive Mimikyu, Weakness Policy for Mega-Gyarados, and the list goes on."

I'll happily admit to being misinformed; you're right about majority of the points you mentioned against the sets I mentioned. Though I think that it's still very important to note the opportunity cost that's lost depending on the set Kyurem uses. While you may have created a set that improves your overall matchup vs mimikyu, you've all of a sudden made it much worse vs other typical threats which kyurem should be able to have a chance of winning against.

There's no denying that Kyurem doesn't have many counters. What I don't understand is how limited counters =/= instantly broken. You say how Kyurem is impossible to reliably win against bar the use of Metagross and Terrakion, which I don't really agree with. Yes, Metagross and Terrakion are going to beat Kyurem in every situation bar hax, though you can't keep pulling out the "It's unpredictable" card whenever an anti-ban argument comes up. If Kyurem's unpredictability is what can help it win many matchups, doesn't the exact same thing apply in that the niche sets it can use can also make it lose a matchup it should win? Opportunity cost is extremely high with Kyurem. If Kyurem was really as broken as what people say, then Terrakion and Metagross would have significantly higher usage than what they currently have (yes, I know that Metagross was #3 in september, but that doesn't explain Terrakion at #68). Also, there are plenty of mons that you can't identify the set of at team preview. While Kyurem does have more of these sets to play around with, sometimes you have to give the benefit of the doubt. It's naive to think that Kyurem could be any one of Kyurem's approximate 8 sets at any given time. You can't turn a blind eye to the popular sets which take majority of usage. Also, these sets beat different things and lose to different things as well. There's plenty of opportunity cost when you run a niche set.
 
(yes, I know that Metagross was #3 in september, but that doesn't explain Terrakion at #68).
It does explain pretty much everything. The fact that this happened in September proves how frustrated people are at this point, not being able to stand the overcentralization around Kyurem-Black in the current metagame.Also, people on the ladder do tend to rely on 1-2 counters, rather than trying to vary their teams, which explains both why Metagross-Mega is in #3 and why Terrakion is in #68.
 
Secondly, you didn't mention the real reason that Kyurem is broken: unpredictability. The argument that you did touch on, in that it has next to no counters, is not to be used as a stand-alone argument. Rather, the fact that A) you can't tell what set Kyurem is at team preview, B) that its sets beat different things, C) Kyurem's niche sets see some usage (1/3 Kyurems aren't running Scarf or Icium) and D) Kyurem has only a small handful hard counters (and most of them have to run off-meta sets to truly counter it) can lead us to this conclusion: that Kyurem-B is impossible to reliably win against unless you happen to be running one of its few counters. In short: it makes you lose when you should have won unless you start running Mega Metagross or Terrakion on all of your teams, which is obviously unfair and uncompetitive.
I'd like to point out that Kyurem can be pretty predictable, or at least, as predictable as other things currently allowed in the meta.
Just about every Kyurem is gonna be hitting you with Dragon/Ice moves, in addition to maybe some Electric/Ground/Fighting/Steel coverage.

Now let's look at Metagross-Mega.
Just about every Metagross is gonna be hitting you with Steel moves, in addition to some Psychic/Electric/Fighting/Ground/Ice coverage.

Both are hard hitters, both have very solid stats, both have very limited, consistent hard counters.
What's the difference? One is considered suspect-worthy, the other is not.

I hate to be the one breaking UC's heart over and over again, but let's take a look at the suspect philosophy:

1) A Pokemon is deemed suspect worthy if it's overcentralizing in the 1v1 metagame, a significantly high usage justifies the large scale it takes in the metagame which is unhealthy and needs to be looked on. This is 1v1 and not a battle between two teams, a Pokemon with high usage proves that its strong and easily splashable on most teams.

Both of these mons have consistently high usage, Kyub being higher than Metagross.

2) By definition a broken Pokemon is a Pokemon that doesn't have a lot of checks and counters. Let's define C&C in 1v1. A check is a Pokemon that can defeat another with a specific set but if it uses another it may lose. A counter is a Pokemon that can defeat another Pokemon no matter what it runs. Ex: Mega Blastoise is a check to Mega Charizard Y if it runs full spdf and mirror coat but Chansey is a counter to Mega Charizard Y as it can always beat it. A pokemon is deemed broken if it defeats at least more than the half of the metagame with a set or its other viable sets without having an opportunity cost, that was the case of Mega Salamence which could easily adjust between two sets and defeat more than half of the meta.

Both have limited counters, HOWEVER, we haven't really considered to what extent a mon has to beat another mon in order to be considered a counter. Some people believe being able to 50/50 a mon is enough to be considered a counter, I believe beating a mon at least 80% of the time is consistent enough to be considered a counter, who's right? Neither, we need our leadership team to decide this, since otherwise, no solid conclusions can be made with this aspect of the philosophy.

3) We do not judge by playstyle since this is 1v1. If a Pokemon defeats a stall team in 1v1 it shouldn't be looked into due to them having a lot of choices to pick from and being having only two-third of the team stallish doesn't stop the last member from defeating a more offensive Pokemon. Ex: If Mega Charizard Y defeats a stall team made of Mega Venusaur, Jellicent and Mandibuzz it's not the Pokemon that is broken, the team doesn't synergize to defeat common threats in the metagame which is your fault, same goes to offensive teams that loses to Chansey. They are S ranked for a reason.

This doesn't exactly apply to evaluating individual pokemon, rather instead a reminder that whether a mon beats your teams consistently or not doesn't matter. It's good advice, and I'm including it here so that way you can tell I'm not cherry-picking from the philosophy post :X

4) We are not looking to make low ranked Pokemon viable in the metagame by banning high ranked Pokemon. It's not our fault if they weren't gifted with a good stats, and movesets to be viable in 1v1.

This doesn't really apply to the Metagross/Kyurem point either, but is also something good to keep in mind, as metagame diversity is not considered good enough reason for banning a mon.

5) Please post your arguments smartly, and do not attack someone's else opinion or attack them directly, this is highly discouraged as it lowers your image and make people avoid listening to you. Some guidelines of posting are: Provide the topic of the Pokemon that you think is deemed suspect worthy, discuss it through the tiering philosophy by providing replays, calcs or strong arguments. Your arguments should provide a clear view of the Pokemon and how unhealthy it is, a list of Pokemon that can defeat it and if it has more than one set then list its sets. Don't bring up the kind of sets that are horrendously niche, they should have some amount of usage on the ladder.

This portion also doesn't really shine too much light on whether a mon should be considered banworthy or not, but is also good to consider, since all posts should offer your personal view of whatever is being suspected/considered, while also having real facts backing up your claims.

6) Being an unpredictable Pokemon shouldn't be a strong trait to base your arguments on but still is a way of view and can be looked on. This is 1v1, it's sure that a lot of Pokemon will have different sets to check their checks and derailing from the norm is always something we should encourage as it helps in giving more life to the metagame. So, let's set up a clear definition of what an unpredictable Pokemon is: It's a Pokemon that can make use of different sets with little to no opportunity cost and still be able to beat half of the metagame with whatever set it runs. Per example an unpredictable Pokemon would be Mega Gyarados as it has a big movepool to pick from, and can adjust itself to beat some Pokemon, but that doesn't make it broken since it comes with some opportunity cost.

HERE we go. Unpredictability isn't really a good argument point unless there's little to no opportunity cost as a result of using the mon's alternative sets.
With consideration to what actually gets used the most, Scarfed Kyurem has the widest metagame coverage out of all its sets, with Icium losing out on a lot of matchups, and Specs at least regaining some of the matchups lost by Icium, but still not being anywhere as close to Scarf.
Metagross, on the other hand, has three different sets that essentially all do the same thing, but have different matchups based on the EV spread and moveset alone.
So in this aspect, Metagross actually surpasses Kyurem in that its three sets all come at little expense over switching between them, while Kyurem loses out on a big chunk of the metagame from not being Scarfed, gaining back very little to make up for that loss from these other sets.

7) Staying on the topic of sets, don't bring in discussion niche sets just to prove that this Pokemon is broken since it can adapt easily, it's just not a good base to build on since most Pokemon can also run niche sets to defeat other.

252+ SpA Teravolt Kyurem-Black Tectonic Rage (175 BP) vs. 252 HP / 0 SpD Magearna: 350-414 (96.1 - 113.7%) -- 81.3% chance to OHKO
252+ SpA Teravolt Kyurem-Black Tectonic Rage (175 BP) vs. 252 HP / 152 SpD Magearna: 306-362 (84 - 99.4%) -- guaranteed 2HKO

8) Don't bring up complex bans they are unneeded and just creates more confusion. Per example if Trick+Choice Item is broken it's not the strategy itself but the user that makes it broken, taking per example Chansey and Meloetta. Chansey will defeat Meloetta even if its tricked if the Meloetta lacks Psyshock but if Meloetta has Psyshock it will be able to defeat Chansey.

I honestly don't have much to contribute to this, but I figured it'd be good to have the entire philosophy restated here for the convenience of people who are trying to get their thoughts together and need some kind of reference to base their post off of.

9) If good arguments are made against a Pokemon the Tier Leader has the right to suspect it, we aren't looking for quick banning Pokemon since the community's opinion is valuable and they make the metagame. If a Pokemon didn't get banned due to a suspect don't re-talk about it even if you still think it's broken, we work on majority.

Okay, let's maybe not take this one to heart, since "good arguments" are subjective to what each individual user considers a "good argument", and the leaders themselves even broke this one by quick-banning Marshadow :X But this also goes to show that in reality, we cannot undo ban/unban decisions as we once may have thought, so please be considerate with how you go about banning/unbanning mons, as decisions are more or less final, unless we get a massive rallying force behind undoing these changes.


Okay, so the philosophy ended up being a lot less about actual suspects than I expected, rather being more about how posts should be made for suspect discussion.
However, in the three portions that DID pertain to my point of Metagross being equally as suspectable as Kyurem, Metagross proved to be about as suspectable as Kyub, if not even more; both have high usage (Kyurem has more), both have limited hard counters (Metagross has less), both are unpredictable (Metagross loses less from changing between sets).

Sorry for dragging your post into this Macey, it was a good starting point for this mess tho-

Massive Metagross post is coming soon to a thread near you!
 
I am not a 1v1 player whatsoever... I am really surprised I managed to get reqs, too. I wanted to write my thoughts regarding Kyurem-B because why not... please pardon me for my zero 1v1 knowledge.

I played some 1v1 games before the suspect test and the first thing I was really paranoid about while teambuilding is Kyurem-B.

Even though Kyurem-B is very versatile, every Kyurem-B set could be beaten by the right Pokémon; there's no one broken set that beats everything. However, this fact put so much pressure on me while teambuilding, if not restricted it to some extent.

During the suspect ladder without Kyurem-B, I was really satisfied with the fact I didn't need to overprepare for Kyurem-B. The fact I had so much less pressure while teambuilding made my overall building and playing experience a lot more enjoyable than with Kyurem-B on the meta.

Even though I had lots of fun messing around with Kyurem-B and its many sets before the suspect test, I have to say I enjoyed the Kyurem-B-less meta more, therefore I leaned towards voting ban.
Tbh, I just like the meta better without too dude. If we can ban Deo-D because it’s less fun, we can ban Kyurem too. I find teambuilding easier as well. Certain weird and bad sets get more room to shine, and certain Pokémon that weren’t great with Kyurem everywhere like Mega-Venu and P-Z are nice to use. Also, not having to guess whether it is z-Ice or Choice Scarf is nice. Char X and Char Y are kind of like that, but to a lesser extent.

Stay around, man. You understand 1v1 well.

Massive Metagross post is coming soon to a thread near you!
It can be hard to concede victory, and I still do think that Kyurem is broken, but I agree with a lot of what you said. There's just something I want to bring up in regards to all of that.

You mentioned a high opportunity cost to using some of Kyurem's more niche sets. A while back, I did a post on predicting what set Kyurem is running (results: you can't predict it). In this post, I made a spreadsheet of everything on the VR vs Kyurem's relevant sets. UOP used his spreadsheet magic to determine what percent of matchups were wins. Note: these matchups were set to be in Kyurem's favor in cases where there is any discepancy about who would win, and is also not weighted by usage as this is what was useful for the purposes of that post. These numbers are useful here, but don't go around spamming them because they aren't accurate. It only works here because I am using these numbers to see how they stack up relative to each other and not anything else.
Choice Scarf: 47%
UOP Icium: 54%
Offensive Band: 54%
Offensive Icium: 49%
Impish Band: 52%
Weakness Policy: 44%
Haban Berry: 36%
Chople Berry: 42%
Choice Specs: 54%
Groundium: 43%
Assault Vest: 48%
Electrium: 46%
Special Scarf: 50%

So really, the only set that has a very high opportunity cost is Haban Berry. Even stuff like Groundium squeezes out well above 40%.

And you also have a fair point in that optimized sets are inherently better than what is actually used, however, the problem with that is as I stated, they aren't used. This leads to another problem that we need the leaders to decide for us; whether what gets used most frequently on a mon should be considered more important than the objectively most opportune sets or not. The problem with optimized sets according to the current philosophy is that they don't have the usage to be considered "relevant" on the ladder, and end up falling off into the "niche" category by technicality; heck, even Gyarados still doesn't run EVs to beat Kyurem most of the time, and it's considered one of its top counters. These sets also lack what would be considered "overcentralizing usage", which means that they're lacking in 2 out of 3 of the aspects within the suspect philosophy that pertain to mons in particular.

tldr; Kyub will most commonly be 252atk/252spe and the VR is not the end-all for everything relevant in 1v1.

I'd go back through that chart if I were you. Off the bat, Blaziken is stated to lose against Scarf, when really it's a protect roll and for some reason Grassium Z Heatran is included?

Nonetheless this info is also useless. I would not be surprised that similar top tier mons would have 40-50% win rates with all their sets. If Kyurem-B is truly unpredictable, what would be important is that each set could beat the same large bulk up mon's and yet changing between sets grant an extra 4-5% wins without losing too many "core" wins.

You took everything I said completely out of context... You have to understand, that as I spent half a paragraph explaining in my post, that I didn't make that chart with this in mind. My original post for which I designed that spreadsheet for was about predicting what set your opponent's Kyub is running based on team composition. So no, this info is not useful for most purposes, and I never claimed it was. All this was meant to do is use a previous resource to attain a rough estimate of the opportunity cost of each set relative to each other. Yeah, other top-tier mons probably would get that same 45% win rate with this method and I never claimed otherwise. This wasn't about proving that each of Kyurem's sets beats about half the meta, this was about, as I said before, analyzing an estimate of the opportunity cost of using niche sets. Yeah, I guess Blaziken should have been a 50/50 scenario. Does it really matter, though? On something that large, you're going to make mistakes period, but each mistake is only going to sway the numbers by an insignificant amount. I feel as if the only part of my post you read was the spreadsheet.
 
So, now that sleep is staying, this was more relevant when I started making this post ;X I'd like to suggest a theory that I believe infamous user 1vI has touched on before:

Metagross-Mega is broken in 1v1

Now, I know you guys must be thinking I'm being even crazier than usual, but a discussion brought up once in the room really opened my eyes. Someone had asked for some mons who counter Metagross 100%, and by the end of it, we were only able to name a few. Pretty much anything else used to check it falls below 80% certainty of defeating one of the possible viable sets.

And with that said, let's consider anything and everything Metagross-Mega can run to be considered viable:

Moves:

Bullet Punch, Meteor Mash, Iron Head, Zen Headbutt, Thunder Punch, Earthquake, Bulldoze, Hammer Arm, Ice Punch/Magnet Rise, Substitute, and Rock Slide/Tomb.

Spreads:

The standard Teambuilder-generated spreads:

EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature

EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature

The optimized spread to withstand Gyarados-Mega's +1 Crunch, Tapu Koko's Gigavolt Havoc, and more, made by the 1v1 community:

EVs: 252 HP / 28 Def / 204 SpD / 24 Spe
Impish Nature

Now let's look at how popular this thing is among the ladder, as opposed to other current top mons of the tier:

1500 stats (The default minimum):

Now that we have an idea of what to expect from the mon itself, as well as how much you should expect to see it, let's look at how often it wins matchups with each set, considering all the moves it could use.

Key:
MAW = Metagross Always Wins - The chances of Metagross winning are about 85% or higher
MUW = Metagross Usually Wins - The chances of Metagross winning are about 60% - 85%
~50/50 = Uncertain for either side - The chances of Metagross winning are about 40% - 60%
MCW = Metagross Can Win - The chances of Metagross winning are about 15% - 40%
MAL = Metagross Always Loses - The chances of Metagross winning are less than 15%

S RANK
Gyarados-Mega
Adamant - MUW
Jolly - MUW
Impish - MUW

Overall, Metagross will typically win this matchup with the right moveset, the odds of success only being boosted higher by how rarely experienced people use max Atk/Spe Gyarados.

Overall, Metagross pretty consistently counters just about anything Kyurem-Black can throw at it, with only a few sets even having a chance given that they're able to either safely take a hit + Bullet AND outspeed for the 2HKO, or getting the lucky roll against a 0 bulk Metagross with Weakness Policy-boosted Earth Power

Bulky
Adamant - MAL
Jolly - MAL
Impish - MAL

Not exactly Metagross' most ideal matchup, most matchups being won typically by Charizard Mega Evolving and Dancing up for the guaranteed OHKO, though Jolly Metagross has a chance by spamming Substitute for the Flare Blitz Recoil before finishing it off with Earthquake, the only risk being that the Charizard might use its own Substitute to automatically win, if you get predicted.

Aggron-Mega

This entire matchup pretty much depends completely on the EV spread of Charizard-Y, as well as the presence of Rock Slide in Metagross' moveset.

Dragonite
Adamant - MUW
Jolly - MUW

There are way too many iterations of Dragonite to go into detail for all of them, but more often than not, Metagross wins simply by hitting Dragonite twice with STABs, or even Ice Punch.

Jolly - MAW
Impish - MUW

Adamant hopes for misses to 2HKO the hustler, Jolly just plain 2HKOs with EQ then Hammer Arm while not getting OHKO'd, and Durant needs Crunch to 2hko the custom spread, while the custom spread 3HKO's with Hammer Arm and Bullet.
Gengar-Mega
Adamant - MUW
Jolly - ~50/50

Adamant has a solid shot of 2HKOing with Bullet, factoring that in with the 40% miss chance and the 33% chance to wake up first turn makes things favorable for Metagross.

Defensive
Adamant - MCW

Assuming GeneMew runs Overheat and ~0 Speed EVS (Most frequent in usage), Metagross wins most of the time by just spamming Iron Head, not even needing the hax very much if at all. Bulky Mew, on the other hand, can only be threatened by Substitute and hax, and even then, the odds aren't really in Metagross' favor.

Regular Pidgeot kinda just loses, with their only chance of winning being a Heat Wave crit/burn, which is less than 1% more likely than Will-o-Wisp missing. The best chance it has vs the famed Bulky Birb, however, is by relying on Rock Tomb without mega evolving and hoping they don't go for Heat Wave when you do so.

Kentari can vouch for probability management playing a big role in this matchup.
Relicanth

Specs Dark Pulse hax makes things uncertain for any Metagross slower, while also OHKO-ing Jolly, usually. Bulky Z move, on the other hand, is a bit more challenging for Metagross to beat, so it ends up relying on haxing Thundy for the win.

Barbaracle

Adamant has a decent chance of 2HKOing max bulk with Hammer Arm, the miss chances bring that down to about a 50/50, though. The other sets just rely on good old-fashioned skill hax.

Slaking

Stunfisk

Ignoring the existence of Sub and Magnet Rise, it's just another round of praying for the 1/3 wakeup for Jolly and Impish, while Adamant pretty much safely 2HKOs with Iron Head and EQ, possibly auto-winning with a Flinch.
Vivillon
Adamant - MUW
Jolly - MAW
Impish - MUW

It takes a lot of hope for Vivillon to win this matchup.


So, looking at this list we have here, we can conclude that there are only ten sets that will about automatically win without needing to worry about avoiding hax or knowing which set Metagross is:
  • Bulky Charizard-X
  • Mega Aggron
  • Mega Slowbro
  • Genesect
  • Ferrothorn
  • Sableye
  • Special Victini
  • Dusclops
  • Mega Camerupt
  • Mega Scizor
All this evidence is to say that Metagross is broken in 1v1 because it has high enough usage to be overcentralizing, low opportunity cost involved in switching between its plethora of move and spread options, and a limited number of more or less guaranteed counters.

Posting a bit sooner than I'd like because computer is threatening me with a restart ;-;
 
So, now that sleep is staying, this was more relevant when I started making this post ;X I'd like to suggest a theory that I believe infamous user 1vI has touched on before:


Metagross-Mega is broken in 1v1

Now, I know you guys must be thinking I'm being even crazier than usual, but a discussion brought up once in the room really opened my eyes. Someone had asked for some mons who counter Metagross 100%, and by the end of it, we were only able to name a few. Pretty much anything else used to check it falls below 80% certainty of defeating one of the possible viable sets.

And with that said, let's consider anything and everything Metagross-Mega can run to be considered viable:

Moves:

Bullet Punch, Meteor Mash, Iron Head, Zen Headbutt, Thunder Punch, Earthquake, Bulldoze, Hammer Arm, Ice Punch/Magnet Rise, Substitute, and Rock Slide/Tomb.

Spreads:

The standard Teambuilder-generated spreads:

EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature

EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature

The optimized spread to withstand Gyarados-Mega's +1 Crunch, Tapu Koko's Gigavolt Havoc, and more, made by the 1v1 community:

EVs: 252 HP / 28 Def / 204 SpD / 24 Spe
Impish Nature

Now let's look at how popular this thing is among the ladder, as opposed to other current top mons of the tier:

1500 stats (The default minimum):

Now that we have an idea of what to expect from the mon itself, as well as how much you should expect to see it, let's look at how often it wins matchups with each set, considering all the moves it could use.

Key:
MAW = Metagross Always Wins - The chances of Metagross winning are about 85% or higher
MUW = Metagross Usually Wins - The chances of Metagross winning are about 60% - 85%
~50/50 = Uncertain for either side - The chances of Metagross winning are about 40% - 60%
MCW = Metagross Can Win - The chances of Metagross winning are about 15% - 40%
MAL = Metagross Always Loses - The chances of Metagross winning are less than 15%

S RANK
Gyarados-Mega
Adamant - MUW

Overall, Metagross will typically win this matchup with the right moveset, the odds of success only being boosted higher by how rarely experienced people use max Atk/Spe Gyarados.

Overall, Metagross pretty consistently counters just about anything Kyurem-Black can throw at it, with only a few sets even having a chance given that they're able to either safely take a hit + Bullet AND outspeed for the 2HKO, or getting the lucky roll against a 0 bulk Metagross with Weakness Policy-boosted Earth Power

Bulky
Adamant - MAL
Jolly - MAL
Impish - MAL

Not exactly Metagross' most ideal matchup, most matchups being won typically by Charizard Mega Evolving and Dancing up for the guaranteed OHKO, though Jolly Metagross has a chance by spamming Substitute for the Flare Blitz Recoil before finishing it off with Earthquake, the only risk being that the Charizard might use its own Substitute to automatically win, if you get predicted.

Aggron-Mega

This entire matchup pretty much depends completely on the EV spread of Charizard-Y, as well as the presence of Rock Slide in Metagross' moveset.

Dragonite
Adamant - MUW
Jolly - MUW
Impish - MUW

There are way too many iterations of Dragonite to go into detail for all of them, but more often than not, Metagross wins simply by hitting Dragonite twice with STABs, or even Ice Punch.
Lopunny-Mega

The only shot Lopunny has is getting lucky with Teeter Dance and/or misses.

Unless Ghostium Magearna became a thing in the time it took to make this, Metagross has this locked down, for the most part.

+2 Earthquake only takes out Jolly on a high roll, but still just gets bopped by Hammer Arm and Bullet anyways.

Durant
Adamant - MCW
Jolly - MAW
Impish - MUW

Adamant hopes for misses to 2HKO the hustler, Jolly just plain 2HKOs with EQ then Hammer Arm while not getting OHKO'd, and Durant needs Crunch to 2hko the custom spread, while the custom spread 3HKO's with Hammer Arm and Bullet.
Gengar-Mega
Adamant - MUW
Jolly - ~50/50
Impish - ~50/50

Adamant has a solid shot of 2HKOing with Bullet, factoring that in with the 40% miss chance and the 33% chance to wake up first turn makes things favorable for Metagross.

Defensive
Adamant - MCW
Jolly - MCW

Assuming GeneMew runs Overheat and ~0 Speed EVS (Most frequent in usage), Metagross wins most of the time by just spamming Iron Head, not even needing the hax very much if at all. Bulky Mew, on the other hand, can only be threatened by Substitute and hax, and even then, the odds aren't really in Metagross' favor.

Pheromosa

Umbreon
Adamant - MCW

The best chance it has vs the famed Bulky Birb, however, is by relying on Rock Tomb without mega evolving and hoping they don't go for Heat Wave when you do so.

Impish - MUW

It takes a lot of hope for Vivillon to win this matchup.


So, looking at this list we have here, we can conclude that there are only ten sets that will about automatically win without needing to worry about avoiding hax or knowing which set Metagross is:
  • Bulky Charizard-X
  • Mega Aggron
  • Mega Slowbro
  • Genesect
  • Ferrothorn
  • Sableye
  • Special Victini
  • Dusclops
  • Mega Camerupt
  • Mega Scizor
All this evidence is to say that Metagross is broken in 1v1 because it has high enough usage to be overcentralizing, low opportunity cost involved in switching between its plethora of move and spread options, and a limited number of more or less guaranteed counters.

Posting a bit sooner than I'd like because computer is threatening me with a restart ;-;
You know if we did this for Mega-Gyarados the list would begin and end with Tapu Koko.

The Quagsire vs Metagross matchup is a lesson in not getting the 1/5000 roll lol.

Latias’s only niche is Reflect Type. Why else would you even use it?

I can’t believe you did every matchup.


Mega-Altaria

Altaria-Mega @ Altarianite
Ability: Pixilate
Happiness: 0
EVs: 128 HP / 44 SpA / 88 SpD / 248 Spe
Timid Nature
IVs: 0 Atk
- Hyper Voice
- Roost
- Cotton Guard
- Substitute

You live z-Hurricane into Extreme Speed from Dragonite. This set used to have cooler moves like Fire Blast, Wonder Room, and Rest. But this is probably the better set. You’re faster than Adamant Lando-T. Between Sub, Cotton Guard, and Roost you have a great Normalium Snorlax matchup.

Metagross-Mega @ Metagrossite
Ability: Tough Claws
Happiness: 0
EVs: 248 HP / 60 Atk / 128 Def / 72 Spe
Impish Nature
- Bullet Punch
- Meteor Mash
- Earthquake
- Thunder Punch

Altaria gets merced by Tapu Lele, so we add the most broken counter to it. This illustrates two things about the way I make teams. 1. I limit my memes to between 1 and 1 1/2 pokemon. Anything more than that and the weaknesses of the bad mons compound on each other and leave you with a bad team. Only Macemaster, Partys Over, and UOP can get away with running teams full of memes, and even they will tell you it’s easier to win with the broken mons. 2. I like to hedge my bets by including more than one counter for a mon. Both Mega-Alt and Metagross beat Gyara, even though I really only need one of them to beat it.

Marowak-Alola @ Thick Club
Ability: Lightning Rod
Happiness: 0
EVs: 148 HP / 200 Atk / 160 Spe
Adamant Nature
- Shadow Bone
- Low Kick
- Stone Edge
- Flare Blitz

I needed something to beat Genesect, Aegislash, and Tapu Koko. Stone Edge kos 0 hp Charizard X. I have 160 speed so that I’m faster than Chansey and can crit it. That’s probably wrong, but this mon’s EVs don’t matter too much. You should probably give it the best chance you can against Mega-Slowbro or something similar. This doesn’t actually beat Aegislash but Shadow Bone isn’t a contact move so sometimes it works out.

This team can’t really beat Mega-Venusaur or Stall, but a little counter-teaming can fix that in no time.

So, now that sleep is staying, this was more relevant when I started making this post ;X I'd like to suggest a theory that I believe infamous user 1vI has touched on before:


Metagross-Mega is broken in 1v1

Now, I know you guys must be thinking I'm being even crazier than usual, but a discussion brought up once in the room really opened my eyes. Someone had asked for some mons who counter Metagross 100%, and by the end of it, we were only able to name a few. Pretty much anything else used to check it falls below 80% certainty of defeating one of the possible viable sets.

And with that said, let's consider anything and everything Metagross-Mega can run to be considered viable:

Moves:

Bullet Punch, Meteor Mash, Iron Head, Zen Headbutt, Thunder Punch, Earthquake, Bulldoze, Hammer Arm, Ice Punch/Magnet Rise, Substitute, and Rock Slide/Tomb.

Spreads:

The standard Teambuilder-generated spreads:

EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature

EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature

The optimized spread to withstand Gyarados-Mega's +1 Crunch, Tapu Koko's Gigavolt Havoc, and more, made by the 1v1 community:

EVs: 252 HP / 28 Def / 204 SpD / 24 Spe
Impish Nature

Now let's look at how popular this thing is among the ladder, as opposed to other current top mons of the tier:

1500 stats (The default minimum):
Metagross-Mega - #6 in 1v1 | Usage: 6.95323% | Raw count: 21,554 | Weight: 0.877542535311

Tapu Koko - #9 in 1v1 | Usage: 8.49073% | Raw count: 26,262 | Weight: 0.00596718576573


Now that we have an idea of what to expect from the mon itself, as well as how much you should expect to see it, let's look at how often it wins matchups with each set, considering all the moves it could use.

Key:
MAW = Metagross Always Wins - The chances of Metagross winning are about 85% or higher
MUW = Metagross Usually Wins - The chances of Metagross winning are about 60% - 85%
~50/50 = Uncertain for either side - The chances of Metagross winning are about 40% - 60%
MCW = Metagross Can Win - The chances of Metagross winning are about 15% - 40%
MAL = Metagross Always Loses - The chances of Metagross winning are less than 15%

S RANK
Gyarados-Mega
Adamant - MUW
Jolly - MUW

Overall, Metagross will typically win this matchup with the right moveset, the odds of success only being boosted higher by how rarely experienced people use max Atk/Spe Gyarados.

Overall, Metagross pretty consistently counters just about anything Kyurem-Black can throw at it, with only a few sets even having a chance given that they're able to either safely take a hit + Bullet AND outspeed for the 2HKO, or getting the lucky roll against a 0 bulk Metagross with Weakness Policy-boosted Earth Power

Not exactly Metagross' most ideal matchup, most matchups being won typically by Charizard Mega Evolving and Dancing up for the guaranteed OHKO, though Jolly Metagross has a chance by spamming Substitute for the Flare Blitz Recoil before finishing it off with Earthquake, the only risk being that the Charizard might use its own Substitute to automatically win, if you get predicted.

Dragonite
Adamant - MUW

Gengar-Mega

Overheat only has about a 40% chance of OHKO-ing Jolly with Overheat, that's pretty much it.
Nihilego
Adamant - MAW
Jolly - MAW
Impish - MAW

You could probably win this matchup without even using physical attacks.
Pyukumuku
Adamant - MUW
Jolly - MCW
Impish - MCW

Sub and Thunder Punch are all Adamant needs, while Jolly and Impish have to go for flinches, otherwise Pyu will usually win this matchup
Sceptile-Mega
Adamant - MAW
Jolly - MAW
Impish - MAW

Why was this even ranked again? You could argue SubSeed exists, but I could argue Ice Punch exists.
Zygarde
Band
Adamant - MAL / MUW (Depends on whether Zygarde outspeeds or not)
Jolly - MUW (Tarrows) / MCW (Earthquake)
Impish - MAW (Ice Punch) / MCW (No Ice Punch) (Depends on whether Zygarde outspeeds or not)

Groundium
Adamant - MAL / MCW (Depends on whether Zygarde outspeeds or not)
Jolly - MCW
Impish - MCW (Depends on whether Zygarde outspeeds or not)

Other
Adamant - MAL / MUW (Depends on whether Zygarde outspeeds or not)
Jolly - MCW
Impish - MCW (Depends on whether Zygarde outspeeds or not)

Ice Punch kinda wrecks this matchup, otherwise, typically in Zygarde's favor.

D RANK
Alakazam-Mega
Adamant - MAW
Jolly - MUW
Impish - MAW

I'll be generous and make Jolly MUW, just because crit Shadow Ball OHKOs.
Aron
Adamant - ~50/50
Jolly - ~50/50
Impish - ~50/50

Without assuming you have Sub, you're basically just hoping for Iron Head flinches.
Azumarill
Adamant - MAW
Jolly - MUW
Impish - MUW

Adamant Metagross 2HKOs pretty easily, while Z-Aqua Tail can be pretty threatening to the other two if they don't get good RNG/rolls.
Clefable
Adamant - MAW
Jolly - MAW
Impish - MAW

S/O to the babiri Counter Clefable I used last gen-
Latias
Adamant - MCW
Jolly - MCW
Impish - MAL

Meteor Mash boosts pre-mega and crits are pretty much all you have going for you in this matchup. Reflect Type always wins, I guess, but Charm is used more/generally better by far.
Necrozma
Specs
Adamant - MAW
Jolly - MUW
Impish - ~50/50

Z-move
Adamant - MCW
Jolly - MCW
Impish - MCW

Adamant 2HKOs with Iron Head, Jolly does the same with Meteor Mash, while Impish relies on Iron Head haxing. Iron Defense Necrozma causes difficulties that can only be solved via haxing.

Porygon2
Adamant - ~50/50
Jolly - MCW
Impish - MCW

Adamant has a decent chance of 2HKOing max bulk with Hammer Arm, the miss chances bring that down to about a 50/50, though. The other sets just rely on good old-fashioned skill hax.
Salazzle
Adamant - MAL
Jolly - MAL
Impish - MAW

Fake Out and Overheat are just short of 2HKOing the custom spread. Z-Fire just kinda wrecks them all, however.
Scizor-Mega
Adamant - MAL
Jolly - MAL
Impish - MAL

This guy is the OU dedicated Metagross Counter for good reason.
Slaking
Adamant - MAW
Jolly - MCW
Impish - MUW (Depends on whether you outspeed or not) / MAW (Hammer Arm)

Banded Earthquake OHKOs Jolly pretty easily, but Flinches put the odds quite a bit less in Slaking's favor.
Smeargle
Adamant - MCW
Jolly - MAW
Impish - MCW

Everyone loves praying for that 1/3 chance at waking up, right?
Stunfisk
Adamant - MUW
Jolly - MCW
Impish - MCW

Ignoring the existence of Sub and Magnet Rise, it's just another round of praying for the 1/3 wakeup for Jolly and Impish, while Adamant pretty much safely 2HKOs with Iron Head and EQ, possibly auto-winning with a Flinch.
Vivillon
Adamant - MUW
Jolly - MAW
Impish - MUW

It takes a lot of hope for Vivillon to win this matchup.


So, looking at this list we have here, we can conclude that there are only ten sets that will about automatically win without needing to worry about avoiding hax or knowing which set Metagross is:
  • Bulky Charizard-X
  • Mega Aggron
  • Mega Slowbro
  • Genesect
  • Ferrothorn
  • Sableye
  • Special Victini
  • Dusclops
  • Mega Camerupt
  • Mega Scizor
All this evidence is to say that Metagross is broken in 1v1 because it has high enough usage to be overcentralizing, low opportunity cost involved in switching between its plethora of move and spread options, and a limited number of more or less guaranteed counters.

Posting a bit sooner than I'd like because computer is threatening me with a restart ;-;
Would just like to add special fightinium z pheromosa, and 252 hp / 252+ spa heatran to that list of mons, and kent quagsire loses to the somewhat (not really) common grass knot, which glyx should include in the move list since it has actually seen a fair amount of usage

Grass Knot is considerable, but doesn't see enough usage, and would also force Metagross to run an alternate nature, since 0- Grass Knot doesn't get the job done.
