I find it interesting so much discussion is being had around Iron Crown here, specifically the double dance set because I would argue it is easily the worst variant. DD Crown is mostly just a low/mid-ladder stomper where people struggle to play around activating its Weakness Policy. The set mandates screen support to be most effective, a playstyle has fallen off substantially and has more than enough adequate counterplay within the tier. Without the aid of screens it is far more easily chipped down and taking a super-effective hit usually brings it into range of any form of priority.
It is dependent on activating its item to be effective due to relying on Stored Power. If its WP is never activated then it requires at least 2-3 turns to be considered a scary enough threat. This just makes it susceptible to any form of neutral chip because it lacks any form of longevity, enough to bring it into range of many Pokemon.
Counterplay -
The tier has so much counterplay to this set assuming the matchup is played well and you don't activate its WP for free with a weak hit. I stopped at B rank so there is probably more especially if you factor in defensive Tera, particularly the popular Tera Steel. Correcthorse's post covers a lot of these also.
Phazers:
Garchomp forces the Tera Fairy at worse but it is a strong answer. Empoleon could not care less about the Pokemon and gets to spam Haze or Roar. Toxapex while being weak to SP easily pivots in to click Haze, with team support you can simply just whittle it down. Hippowdon is similar to Garchomp where it is bulky enough and can run Whirlwind. Ttar offensively threatens it and has the bulk to stomach Tachyon. Has access to Dtail and Roar also.
Encore:
HO has access to Lucha with a fast Encore and is faster if Unburden is activated. Ogerpon also being another candidate to do the same despite being slower than +2 Crown. Tinkaton doesn't take too much from Crown and can lock it into either a boosting move or Tachyon.
Unaware:
Tera Dark or Steel beats it.
Offensive:
Azumarill hits hard enough and has priority. Lokix is immune to SP and has strong priority/U-turn. Greninja resists both STABs though admittedly isn't amazing into Crown if screens are up. Bisharp, Scizor, and Excadrill can just boost alongside Crown and threaten to do way too much even behind a Reflect as Crown does not do enough without several boosts to threaten them. Metagross can break screens and then spam EQ to weaken it. Ursaluna just hits too hard, EQ does 70 min behind Reflect.
The King:
You don't beat Crown 1vs1 but you get to Twave it and chip it down or TP out into other partners
Even if Garchomp was booted from the tier we would still have more than enough means to limit this set. The only way I see it becoming an issue is if Focus Blast becomes popular enough over Tachyon, as it changes several of its matchups. Though running that move has its share of issues. Regardless I don't think DD Crown is remotely threatening enough right now and if anything Specs and Booster CM would be the main sets to keep an eye on.

I personally didn't like Zapdos in the tier to begin with, but now it feels like a pretty obvious mon to keep an eye on. it already wasn't too bothered by chomp, but the only grounds that beat it are rhyperior(who isn't that good otherwise) and mamoswine, speaking of..
I still believe in him, but mamo just lost its single best matchup. there's still a lot of mons it beats and it's ground type is better now since aren't competing with chomp, so I don't think its mamover yet
Uh oh, this guys probably gonna be broken. Chomp was a common counter, but with it gone, moth doesn't need to run dazzling gleam anymore. This means it use that last slot to pick and choose the checks it can beat(sub and tera ground seem terrifying now) making it even more of an annoying matchup fish.probably banned.
if you didn't see enough drill, good news! Its now the best ground type in the tier.
bro needed this.Now that most things don't need to run ice moves to beat chomp, and the best physical sweeper isn't a dragon (maybe,)
we lost the most common switch-in to it. the dog is happy.
Bye air balloon, hello leftovers(air balloon will probably still be used since it wasn't really even a chomp counter)
same deal as tink and drapple. Was already great, but the chomp weakness was a major turnoff for some, so now it might finally rise to uu like it should of already
This is my weirdest prediction, but now with tankchomp gone, Gastrodon could rise as a defensive ground with spikes to fill that void. decent chance this won't happen but still could worth looking at
(no hisui pic) we lost the most common switch-in to it. the dog is happy.
this guy was extremely outshined by garchomp as a sweeper in the tier, maybe this guy's usage can be higher as its versatility is insane he can run sd + scale shot, clangorous soul, dragon dance, bulk...up(?) and belly drum, and even use its 125 defense to be like tankchomp, stuff like this shouldn't be passed up on and i hope the playerbase realizes his true potential soon !
My boy got buffed and he fell to RU in the same gen, losing the chomp matchup wasn't good so hopefully he can actually comeback, combines the best defensive types in the game, has rocks, knock and flip turn and roost for recovery, combined with tera and he can actually be a nice wall so hopefully he comes to UU soon
she's now backup ground since garchomp went to jail and is actually really strong combined with LO sand rush or mold breaker to hit latios and rotom-wash, please do not ban this thing for being broken with SD + Rush
this will not drop she's good
it might be mamover guys
WE MIGHT BE URSABACK
with chomp gone, this guy could be a very scary threat, chomp was the only thing checking this thing and another check (choice scarf latios luster purge) ties with quark spe and could tera so moth might actually 1-up him, will probably get banned in the future for sure
while i don't think iron crown is broken per say, it can snowball out of control given the opportunity, there are things to check it like excadrill and lokix but other than that it can just sweep on a whim so i'd say keep an eye on this
maybe? its battle bond sets are annoying but there's lokix so i guess, i run protect to actually mess with lokix so that could be thing ig
i think is a loser here. Weather Ball sets lose a target and he will have more of a problem dealing with other grounds. Chilling Reception Weather Ball was a nice tech against Chomp, Tios, Dos and Torn but now it doesnt hit Chomp and none of the other Grounds are weak to Ice. I could see Scald becoming more prominent option.
