No longer requires Dark or Ghost coverage in its movesets and can more freely use moves like Encore or Trick. Additionally it can use more Psychic moves to hit Poison types and hit almost everything nuetrally with STABs + Psychic.
This is true. While I don't think Trick Valiant is that great, it does pose a huge threat without gholdengo's existence. People have already started talking about it getting suspected as well even despite gholdengo's existence, and I dont really want to keep one broken mon just because of another broken mon. This should be looked at as well. Playing devil's advocate simply for the sake of it, there are still mons that can exist that wall certain sets. Glowking is still an issue for the special variant as well as hatterene if it doesnt continue to run shadow ball. Obviously there are other valiant sets that do beat glowking/hatterene but that is also true for gholdengo and a reason this mon is being discussed for a suspect.
Besides Gliscor (also on Radar) and Tera’d Garg, it can spam Dire Claw and fish for Status uncontested besides against Steel types (You know, the perfect Fighting type check). It can also run Tera Blast Ice for likes of Gliscor and Landorus-T without having to worry about being cucked by Gholdengo.
Also true another great pokemon that finch seems to have a personal vendetta against (with decent reason dire claw is a funny move even if it is a bit inconsistent.) Gholdengo is one of if not the proper mon holding this thing back by being a steel type (immune to poison) while being a ghost type (immune to fighting). Other mons can come in and deal with this thing as well tho including gliscor, glowking (so long as its not running night slash), pex, amoongus (other than unburden acro)... any poison type really thats viable in OU is a potential wall. All those things really fear is sleep from dire claw which has always been the thing that makes everyone look suspicously at sneasler. Also worth testing regardless of ghold's inclusion. Again i dont want to keep broken mon just cuz it checks another broken mon just ban both.
Can simply run Fighting coverage now to deal with Steel types, something it couldn’t do before because of Gholdengo.
Here's where i start disagreeing. Yes Cornerstone is a great offensive threat and one that im very aware of. However, a few things hold it back from being outright broken without gholdengo. 1 is this pokemon has an incredibly hard time coming in due to its lack of resists. It would need help from slow uturns/chilly reception which offers a bit of a restriction when slotting this into a team. 2 is the same thing with other ogerpon forms where it cant really easily be fast or a sweeper or even surprise you in any way, its biggest threat to the meta would be in its ability to consistently get kills every time it comes out. 3 is that unlike waterpon and firepon, i do not think rockpon is getting kills everytime it comes out. While you say it can simply run fighting coverage, this completely ignores bulky fighting types that would be able answer rockpon. Pokemon like conkeldurr and kommoo become much more useful once gholdengo is gone, so they would naturally exist in the tier to answer cornerstone. Cornerstone can run play rough but that is the same issue it faces now where it is forced to chose between 1 of 2 moves.
Body Press has 1 less Ghost type that completely blocks it. Like with Sneasler it is also now more free to use options like Play Rough, Psychic Fangs, Iron Head, or Ice Fang to break past other checks
Personally i think this mon is already placing a huge constriction to the ou tier, just at a lower threat than other mons that are currently being looked at. But if ghold was the only answer, or even close to the only answer, this mon would have been removed a long time ago. Dragapult, enamorus, dozo, clefable, gliscor, hatterene, valiant, ribombee, pex, moltres, and zapdos all can check this thing depending on sets and thats without looking even into uu for other sudo-viable ou mons that would check it as well (skeledirge/amoongus/pelipper/tornt).
+2 Boomburst with Fighting and Dragon STAB is incredibly hard to wall, especially with Tera Normal providing STAB and reducing weaknesses
This is currently not even an ou mon and i dont really see it rising anytime in the very near future. Granted bax and roaring moon also had a stint in UUBL so i think this is worth considereing. KommoO has a lot of options and i think it is an excellent wallbreaker even now. However there is a lot holding it back even with ghold's absence. Clodsire (and blissey to an extent) can be a big problem for this mon unless its also running specific coverage that allows it to deal with those mons, relying oftentimes on splitting ur offenses into running physatk as well as spatk investment. Dozo and corv can equally be a bigger issue to the physical sets. +2 tera normal boomburst on a mixed set is very powerful tho. The other thing is that I mentioned this is a great wallbreaker, not a sweeper. This thing even at +1 speed has a hard time sweeping anything with the existence of scarf enam, scarf wake, any additional fast scarfers, booster speed valiant and moth (which are very present in current ou), as well as many forms of priority (suckerpunch from kingambit being surprisingly notable if you do decide to tera normal and drop ur resist). That as well as the fact that it takes some time to setup im not sure it lives up to the hype
No longer has to deal with Air Ballon Gholdengo, or regular Gholdengo as it can more freely run coverage for Corviknight and Dragapult too.
Dozo, bulkier tusks, clef, ting lu, big zama, even garg and skeledirge can all bother this thing depending on sets as well. There isnt really 1 set that can deal with everything while still doing the dumb broken stuff it would do in dd espeed. That and many of us are finding dragonite setting up to not be quite as free as it may have felt before. Either way there are answers that arent air ballon ghold.
One of the biggest offensive Steels being gone means its Aurora Veil is much easier to set up and leading to shit like this being much easier
252 Atk Choice Band Tera Dark Hoopa-Unbound Hyperspace Fury vs. 0 HP / 0 Def Cloyster in Snow with an ally's Aurora Veil: 76-90 (31.5 - 37.3%) -- 86% chance to 3HKO
252+ Atk Tera Normal Dragonite Fire Punch vs. 0 HP / 0 Def Frosmoth in Snow with an ally's Aurora Veil: 186-220 (66.1 - 78.2%) -- guaranteed 2HKO
252 Atk Choice Band Slaking Body Slam vs. 0 HP / 0 Def Weavile in Snow with an ally's Aurora Veil: 115-136 (40.9 - 48.3%) -- guaranteed 3HKO
And plenty more examples
Veil for sure still an issue. However im more cool with veil in a metagame where i can run defog to get rid of it consistently than in the current metagame.
And yes, all these Pokemon have different checks and counters too, but Gholdengo fits on a lot more teams. Like Skeledirge can check Iron Valiant, but is more suited for bulkier teams. Garg can safely switch into Dire Claw but would also need to Tera Poison or Tera Ghost to not be dunked on by +2 Close Combat off 130 Atk or the surprise Gunk Shot. And Garg fits better on bulkier teams.
It fills a similar role in OU as Landorus-T or Great Tusk because it can check so much while providing multiple roles at once.
TLDR yeah like u said there are answers to all these mons and gholdengo works well as amazing glue to answer all of these. That being said I dont think being glue is enough of a reason to stay around when A) gholdengo is impacting the rest of the meta by making hazards broken b) some of these mons ghold is being glue to are worth banning regardless C) enough answers exist to the rest of the mons such that the glue it provides is not necessary. I like glue tho as Im sure everyone else does. I'm praying the murmurrings of aegislash's return in DLC2 are true so we can get a gholdengo that exists in the tier without having one of the most laughable abilities GF has ever created.
