before you yell at me "defog entei!!!" or "tspikes exist now!!!" or "necrozma is broken!!!!!" i'm writing this before the post-slate 10 meta has completely settled and before we've figured out how everything fits in.
i might make a post later talking about how stupid the new mons are (because they will be)
so lets get to it
Spikes and Entry Hazards in General
why are there so many spikers
there is literally zero good hazard removal in this tier. Yeah, there are spinners, but none of them can touch sableye too much. Even Tsareena the best of the spinners can't hurt sableye too bad because even max attack adamant Power Whip isn't a 2hko on mixed def and pdef sets, and tsar then gets threatened out from the possibility of Wisp burns or Knock Off removing its boots.
The other hazard removal in the tier (Whimsicott, Mantine, or Salazzle Defog) is pretty bad. Whimsi and Mantine do have the added bonus of threatening Sableye a whole lot and forcing it out (meaning it can't spam spikes as much) but are still pretty subpar as defoggers. Mantine is the best of the bunch, also being the tier's only defensive water, but no reliable recovery while most of the spikers do have recovery makes it a shaky defogger at best.
Whimsi has different problems, in that it struggles to fit all of the moves it wants. Defog whimsi is definitely viable, but not being able to hurt bastio too much and having consistency issues (8 synthesis PP, relied on a lot for defensive support, prankster sets can't defog on croak, etc.)
We need more defog, good spinners, or SOMETHING to deal with this completely hazard-centric meta.
Sylveon
> clicks rude parting
> doesn't get punished for it
> refuses to elaborate
and there is like no counterplay. Boots, Specs, Lefties, even something like Pixie Plate. they just click buttons and its not fun. There's no punish except entry hazards(which tbf are on the field 99% of the time bc the hazard removal SUCKS in this meta) and even then, boots sets are great. Clicking rude parting has basically zero drawbacks.
In all fairness, Sylv isn't as busted as it was before (bastio buff, croak, obama, w.e) but its still really annoying and shouldn't be able to spam rude parting as much as its able to.
make rude parting a contact move or something, something to make it actually punishable.
Sableye
sits around and DOES NOT DIE. It's impossible to spin against (even coverage from the spinners does nothing to it, magic guard means it can't even be worn down throughout a game). It spams spikes all game and is really really hard to break even with strong neutral attacks ( 252 Atk Choice Band Toxicroak Knock Off (97.5 BP) vs. 252 HP / 252+ Def Sableye: 153-180 (40.9 - 48.1%), 252+ Atk Tsareena Power Whip vs. 252 HP / 252+ Def Sableye: 147-174 (39.3 - 46.5%)) and just wisps the physical attackers and knocks them off. Its an extremely suffocating presence, making fat / balanced spikes teams very hard to break through. Heavy-Duty Boots somewhat help with this, but the fact that Sableye can spam Knock Off presses the issue even further.
This guy needs a nerf, bad. drop its defenses a bit (85/90/90 should be much more manageable) or at the very least give us some real defoggers PLEASE.
scrappy spin when
Bastiodon
bro is fatter than pex. need i say more?
anyways, this guy isn't really "broken", per se. being this fat is honestly kind of necessary because it softchecks like 2/3 of the tier in one slot. It eats even STAB super effective hits and dishes out toxics and strong body presses back.
If stuff ends up getting nerfed, this guy has gotta be one of them. Its bulk is extremely necessary in dealing with the barrage of stupid wallbreakers this mod has, but if (when) we nerf the worst offenders we really need to make this guy actually breakable.
The only real nerf it needs is to remove bulletproof. Making it immune to random focus blasts from specs duraludon and w.e is annoying
Once other things actually get nerfed and we dont have to rely on bastio for literally everything, removing slack off is a potential option to make it less omnipresent.
please guys sub some defensive mons we have like 2 defensive cores (and all of them have bastiodon)
Toxicroak
sir croaksalot is basically the #1 breaker in the meta. It's extremely hard to safely switch into either CB- or SD- boosted Gunk Shots and Knock Offs. it can literally just spam knock off and there's not too many punishes. You'd think that Bastiodon would be a good check, but then it pulls out the +2 LO close combat and blows you up. Dry Skin makes it more annoying, meaning it can switch in completely for free vs bulky waters (read: Mantine) and not even fear a scald burn. Its biggest flaws are its sometimes lacking power and 4MSS. It wants to fit so many moves on its sets (SD, jet, CC, knock, gunk, sucker, liquidation, EQ, stone edge) that it may or may not have the moves to absolutely destroy you. Its power can sometimes be a bit lacking, but high powered STABs in conjunction with lots of boosting options make it extremely dangerous.
Honestly, this guy isn't the most broken, but CC puts it on the border of impossible to safely check. lower the power of its fighting coverage options or just remove them entirely.
My thoughts on all mons in the meta
In alphabetical order:

Abomasnow: this mon hasn't been tested too much, but so far it seems pretty fine. The only thing to really look at is Kings Rock, but its not that bad.

Arcanine: Great mon. great role compression and good matchups vs the general meta.

Ariados: Relatively niche mon, but does what it does well. It can run band, specs, scarf, or webs sets. It's not the greatest because its walled by the omnipresent bastiodon, but webs are hard to deal with in a meta with barely any hazard removal..

Bastiodon: I have already given my thoughts on this guy. Get rid of bulletproof, potentially get rid of slack off.

Druddigon: Drudd has a niche as a pretty good spikes / rocks setter and paralysis spreader. Rocky Helmet + Rough Skin is really nice and it also can use Mold Breaker to spam paralysis on anything not named Eelektross, Sylveon, or Stunfisk. Has Dragon Tail and STAB Iron Head, alongside great coverage options. Needs to be explored more.

Duraludon: One of the worst mons in the meta. It can be used as a pretty okay specs user as it has the highest SpA in the meta. Its dark pulses and flash cannons definitely do sting, but dark pulse isn't the most spammable move when there's a lot of great dark resists. It has Focus Blast which would be great coverage, but then you remember bastio has bulletproof for some reason.

Eelektross: Pretty mid mon but still good. Can run physically defensive sets to good effect and can also run Coil sets. Both are pretty good. Has good role compression as it is a ground immunity and has good utility and coverage.

Eldegoss: exists i guess. Not a great spinner because sableye and tsareena exist, but it wishport + regen is nice. Can run unaware too. This mon also needs to be explored more.

Emolga: fucking sucks. It had initial hype as it seemed like it
could be good, but it didn't live up to it. Its too frail to be a good arcanine or ground check in general. Its also pretty weak even with transistor plasma fists and it doesnt have the coverage to deal with the grounds. Most of my thoughts are basically summarized by
Runoisch's post. This thing needs a lot of buffs. Give it more speed, make it stronger, give it a bit more coverage, just something to make it useful.

Espeon: Pretty mid mon. It has some utility with a choice specs set because it has trick and good power with STAB psychic and coverage in heat wave. It can also run SubCM with magic bounce to set up on bastiodon and be hard for more passive teams to deal with. It doesn't really need any changes.

Granbull: Granbull is a pretty good mon. poison heal is good on on any mon, and granbull is no exception. It is very bulky and it can set up on a lot. Taunt BU, BU 3 attacks, Wishpass, and more are all good sets. bulk up sets in particular are pretty hard to deal with. STAB Facade is very strong and with its good bulk it does well.

Grapploct: its tempting to use SD sets on this guy, but its defensive capabilities are pretty great. Checking houndoom, persian, and various ground types is really nice. slow flip turns are good as ever. grapploct is a pretty okay mon and doesn't really badly need anything.

Houndoom: Great mon. Pursuit support, offensive capabilities, will-o-wisp, toxic spam, and more. Has a lot of utility options and has pretty good power to back it up.

Kingler: i haven't seen it a single time since it was nerfed. that should say enough about it.

Mantine: By far the best defogger in the tier, and the only bulky water. It has a lot of good utility being able to soft check a lot of things, but no recovery holds it back. Give it roost back, ty.

Perrserker: Is okay on sticky web teams. it has a lot of power but its pretty niche. maybe buff its speed a little bit, because right now its almost completely overshadowed by Tsareena. It has some good qualities, but outside of webs its not very good.

Persian: Great wallbreaker, good utility. It can spam triple axel all game and its punished by almost nothing. Ice is a pretty good offensive typing even though its neutral to the two big grounds, and it hits really really hard. ice shard is as good as ever to revenge kill all sorts of things. persian doesn't really need anything else.

Sableye: i've already gone over sab.

Salazzle: Salazzle is a pretty good mon. Corrosion Toxic and NP sets are good. nasty plot sets are definitely not as good as they were in previous slates even with the buffs, but still need to be accounted for in the teambuilder lest you get absolutely rolled by taunt NP lazzle. Corrosion sets are also really good, being able to spam toxic on everything. It lures in and taunttoxics bastiodon, meaning croak, sylv, and everything else go wild. Good mon, but give it roost!!!

Sandslash: unnerve ground = good. has spin, spikes, rocks, and pretty good coverage. It has fallen out a bit now that sable has been really discovered, but still good. softchecks a lot of the special attackers in the tier.

Slowbro-Galar: I don't really have any thoughts on this guy, it hasn't been explored too much. RegenVest sets look promising, alongside QCQD nasty plot and belly drum sets.

Stunfisk: has some utility because of intimidate, but its overshadowed a lot by arcanine. not having any 4x weaknesses is nice though. it can spam para on stuff and has good utility options, another of the many mons that need to be explored more

Sylveon: i've already gone over sylv

Tauros: Has good power with SFLO and adaptability sets after the buff, but it needs to be explored more. Its not very splashable beacuse it brings almost no defensive utility.

Toxicroak: already gone over croak

Tsareena: The only good spinner in the tier. It has play rough to 2HKO sableye, but its still not too consistent. Tsar has good coverage and power alongside reliable recovery and spin, its a great mon. Hard for most teams to switch into.

Whimsicott: good utility mon. can even go offensive with a choice specs set because it has switcheroo. Both sets are great.
