Regarding the bolded bit and tiering practices: "That closely rated" is outside of the margin of error, so they are not truly that closely rated. Gliscor has been >.25 higher across both of the last two surveys (and generally I see margin of error as between .1 and .2 depending on the sample size of qualified, which is quite large for these surveys in particular).don't really feel like writing something long but i strongly disagree with lily's sentiment that the addition of defog corv and weezing wouldn't be massive differences in terms of alleviating the stress of hazards on the metagame, or that they, especially corviknight with ID, are incredibly passive and easy to take advantage of. If both Gholdengo and Gliscor are that closely rated on the survey, I think it's genuinely awful order operations to suspect Gliscor first.
The only time we suspected something that had such a large disparity lower than other potential suspects ever would be Ursaluna-Bloodmoon, which was because the metagame was still in its infancy and strategies were still evolving. That is not a comparable case to this at all. It would be a misuse of data and undermine the point of having surveys to act on Gholdengo first to begin with.
If we want to have a system that runs on data rather than just a group of people behind closed doors, then we need to use the data consistently rather than throwing it out when it is not convenient to personal narratives. If you wish to argue against survey based tiering, be my guest -- that's probably for another place at another time, but sure. But if you see the numbers as they are and agree with surveys being instrumental in our process, then there's no "that closely rated" with these relative data sets.
Regardless of this, I feel this thread is really misunderstanding the conditions that Gliscor is being suspected under. Yes, it is a very good Spike setter, but it is far from the only reason why it would be suspected. It has unmatched survivability for something that can be a catalyst for so much progress. Swords Dance variants have begun to take off, slow pivot variants are foundational pieces of many great teams, and Knock Off (for opposing Heavy-Duty Boots) variants pair so nicely with other hazard setters that are not just Gliscor itself. Its collective presence with options like SD variants and Toxic or Knock Off creates plenty of uncomfortable situations in the builder and battle itself. For a Pokemon with such a convenient mechanism for entry and health maintenance, it easily qualifies as a tiering topic through the scope of a utility Pokemon. Spikes absolutely contributes to that and is one of the biggest factors, but let's not pretend it's just black-and-white because Gliscor is the best Spiker as it is not close to that linear.
And regardless of that, I do not understand this sudden entitlement people are assuming for Defog users to be able to Defog. That has never been a staple of our tiering -- Corviknight being freed up would surely change the metagame a great deal, but blocking it alone is not enough to ban something or particularly close. Yes, there is more to it and yes, I agree Gholdengo has a ton of other things going for it -- if it were up to me, I would personally vote ban on Gholdengo probably (and certainly am in favor of suspecting it right after), but a lot of people are missing the mark.
