SS Ubers Half Stall

[Flatemo]

Team : https://pokepast.es/aba6e941e988a020

I don't really like running Zacian because it can be walled by Quagsire and counter killed by Scarfed Darmanitan-Galar, Ditto, and Other Zacians

Eternatus is for Bulky offense or stall
Eternatus can wall almost anything that isn't hasn't set up yet once it goes for Cosmic Power, even Zacian!
I replaced Toxic with Dynamax Cannon because it can't deal much damage with just Flamethrower
And when it's faced with an offensive Eternatus it can't do much against that so I just run Dynamax Cannon
+16 Speed to out speed any non-scarfed Pokemon with base 100 Speed or less

Blissey can be a switch in wall for High damage SpA attackers
4 Defense IVs because Blissey is still One-Shot even with 252 defense EVs and two shot by Psystrike Mewtwo
Thunder Wave supports anything that can outspeed Mewtwo
I don't really like running Teleport because statuses are extremely annoying

Quagsire is a Physical Wall
Quagsire with Rocky Helmet can wall strong physical attackers
Since Quagsire is Water/Ground it is only weak to Grass types are resists steel moves
Scald is a pretty annoying move to ruin the opponent's attack with burn
It can also survive Mewtwo's Psystrike but in 2 shots
I don't find Curse that great so I use Haze to counter setup Sweepers

Excadrill is for Stealth Rocks and anti-hazards
Rock Tomb to lower the Speed of Faster mons so that they are forced to switch
I don't really like running Steel Beam because it's like Explosion with no damage
Earthquake can deal a lot of damage to Low Def mons

Mewtwo is the Wallbreaker of this team
It can 2 hit Blissey and Quag, and deals lots of damage to Toxapex
Fire Blast for Ferrothorn and Zacian
It may also be a Sweeper once Faster pokemon are taken out

Gyarados is the Main Spotlight of this team
Lum Berry because burn and paralysis is annoying and I don't like running Heavy-Duty Boots on it cause it only does small damage on Gyara
If Gyarados set's up Dragon Dance without disturbances, it's almost GG for the opponent
Quagsire can counter Gyarados because of Unaware but if it's Gmax it can 2 Shot is with Max Geyser

Overall I think this is a pretty good team
Please tell me your thoughts on it!

Pretty solid team, it checks off most of the boxes for a good balance team. Quagsire checks zacian, blissey checks special attackers just you gotta pivot around on lunala psyshock, and eternatus checks a lot of mons overall. The only problem is that the second half looks like a hyper offense team, so the mons have to be changed for more support roles, mainly just excadrill. Hazard leads on a balance team aren't needed, so I thought a defog mon that also covered the excadrill weakness would be good. So I went in 2 directions with how to take this team. The first one was just make excadrill corviknight and give you some more options to choose from in terms of items. https://pokepast.es/bd2cbbb54e0ae4fc The problem with this one is that it loses hard to kyurem black, one of the biggest threats rn. This second update on paper looks to cover more things while also being less reliant on shed shell to not lose to gothitelle. It trades quagsire for necrozma dusk mane and excadrill for rotom wash which checks both opposing excadrill and gyarados. The team was really solid to start, juts needed some changes to mold itself together into a synergized team. One more possibility if you find hazards hard to remove against maybe offense is heavy duty boots gyarados alongside those items, but I think this final version is really solid and keeps the main idea of a balance team with the really strong 2 hitters https://pokepast.es/b9103fc607f0ab2a .

EDIT: I noticed a weakness to dragapult, it's manageable with smart pivoting between blissey and necrozma, however it is a threat. A possible option to look into is also tyranitar>blissey as the special wall, but if you figure it's something you can deal with then blissey will work fine still.
Tyranitar @ Leftovers
Ability: Sand Stream
EVs: 252 HP / 56 Def / 200 SpD
Careful Nature
- Crunch/rock slide
- Stealth Rock
- Thunder Wave
- Rest/earthquake/rock slide
This set lives jolly +1 life orb dragapult max wyrmwind without dynamaxing itself and is a good option, or you could just go full sp.def. The moves have slashes just for options, I like using all the first listed moves personally, but they're all solid.
