As a Former UU Player, I'd like to briefly explain why Maushold is actually not scary or broken. Good? Yes, but definitely not Busted;
-Firstly, you've forgotten a third counter; Steel types. And, uh... Maus really lacks the tools to handle them on its own. Non-stab Low-kick really doesn't do enough damage to most steels, even with a tidy-up, and by contrast, pretty much all of them barring Tinkaton can KO back from full HP. (Tink, however, brings her own issues to the rats)
Now, if its a Lucario or an AV Magnezone,
and it switches in on a pop bomb, yeah Maus wins, but at that point your opponent more likely just has a skill issue, or you've already won.
(This also includes
Yuri Rock Diance and
Mecha Godzilla Iron Thorns, but just saying "Steel types" was simpler.)
-Secondly... The ghosts don't really fear Technician bite. Like, maybe if your sole ghost type was Bramblegast, you'd be scared, but most other ghost types in the tier like running choice scarf, so they really don't have to fear any flinch hax, and of the ones that don't always run scarf, neither Mimikyu nor Basc fear Bite anyways, as like with Low-kick, non-stab bite just doesn't do that much, though unlike with steels, the flinch hax are real here.
And this is all talking before considering bulky tera ghosts like Chesnaught, or... I actually don't know what other pokemon like tera ghost, but I'm sure there's a few.

-Forth-ly; The tier has multiple, very bulky intimidate users, and more then most pokemon, Maus HATES being intimidated, because Maus' whole thing is "Click button, Kill", so if it can't do that, and has to rely on its 74/70/75 bulk to survive... against pokemon with at bare minimum 110 attack...
Yeah no, that Maushold is 'bout to become a Mausoleum.
-Fifth-ly;

-Lastly, and most importantly;
PROTECTIVE. PADS. SUCK.
Really think about this for a minute; Think about
why you run wide lens.
Population bomb, as a move, rolls a 10% chance to miss every hit. Zoom lens brings that down to a 1% chance, practically guaranteeing 9 - 10 hits every time you click the move. As it was balanced, most pokemon need 8 - 10 hits to ohko with pop bomb.
With a Wide lens, each successive hit adds less then a single percent of a chance to miss and stop the combo. For the sake of argument, lets say it's half a percent chance added on each time (It's higher then that, but probability maths is dumb and stupidly complex and this is for illustrative purposes), so overall, with wide lens, you have about a 6% chance of only getting 9 hits, and about a 5.5% chance of only getting 8 hits, which if you hit that chance, could result in your Maus' demise. But that's still a far better chance of landing all 10 hits with the lens then even landing one without.
When you take off Wide lens to put on protective pads, you are now fully exposed to the brunt of the 1/10 RNG per hit. Using a similar stat for the sake of argument, we'll say each successive hit has an extra 5% probability of missing and ending the combo (Again, for illustrative purposes, the actual number is way higher). So, you have a 10% chance of getting 0 hits, a 15% chance of getting 1 (The same odds as missing a fire blast or hydro pump), a 20% chance of only getting 2, etc, etc. By the time you reach 6 hits, you have a
40% chance of stopping right there. By the time you reach 8 hits, you now only have a 50/50 shot of going to 9 hits.
In order to reach the kill threshold of 8-9 hits on most pokemon, you need to get lucky not
once, not
twice, but 8-9 times
in a row, with
worsening odds each time, and you need to do this
multiple times a game if you plan on sweeping with Maus without a zoom lens
.
Meanwhile, Your opponent needs to get lucky
Once and bam boom bing, Maus is dead and you probably only took out their weakest pokemon unless you got
really unlucky, or, as mentioned before, your opponent has a skill issue.
(And mind you, all these numbers are actually
HIGHER then mentioned here, I just used 5% to simplify things)
To put it another way, without getting into the stupidly complex maths, you're basically on average reducing your Maus' Damage by somewhere in the ballpark of 25-30% over the course of the game, when your Maus
NEEDS all the damage it can get...
And all this... so you don't have to play around a
single item on a
single pokemon that's usually
obvious which one it is.
Let me be clear; Maus is good. Not just as a damage dealer and mid/late game sweeper, but as a support pokemon too, with tidy up and a threatening move for other supports in Population Bomb. It
looks good, because it
is good.
But calling Maus even remotely close to broken is laughable at best, when its answers are so varied and common and exploitable.
It certainly will have a tangible, visible impact on the tier, as will the rest of the UU Drops, but it won't warp the tier around it anymore then Politoed or Ninetails or T-tar. The pokemon that check it are common, the item that ruins it is already good with the multiple fake-out users, and the strategy itself is extremely obvious.
Maushold will be a very notable pokemon in the tier, but it's nowhere near gonna warp it any more then the weather wars will.
Edit: Gamefreak put two lens items in the game that both improve accuracy specifically just to mess with me in this specific moment. 'Zoom Lens' even sounds like the more correct option of the two.
