Well Well Well. Guess who it is, the fun police, SpamtonZZZSpamton, here to nickpick some random stuff I saw as a scrolled down. So, let's begin.

Mind Plate
Which mon uses this? Like actually what uses this. The only thing I can think of is as a improof tool for another mon on your team, but what WG mons are weak to Psychic that you need to defend?

Focus Sash
If Shed Shell gets S, then this should as well. Sash is the Shed Shell of HO. Like 3/4ths of the team has it. And, just like Shed Shell, Balance can very well use Sash. I know you are the stall guy, but this item is one of the main reasons why magic guard is so good.

Assault Vest
I know you are gonna say something like "Why do you care about the low tiered stuff Spamton, stop being a dumbass and get a job", but actually what uses this. Still, it is a lower tier item, so whatever.
Anyway, I can stop my rivalry with Yourself for a sec to talk about other...strange takes I saw.
This move is extremely defining. I think for a move tier list, the best way to look at it is in how different the meta would be without the move. And without shell smash, this meta would be extremely different. Honestly, I would debate that this move has had a bigger impact then Photon, because the dark type would have been good even without photon because of moongeist.
Ice shard is the only thing keeping Zygarde in check. I think it should be slightly higher.
What does this hit? Like Zygarde and MRay I guess? But you know a move that hits both of those mons much harder, and hits more then just those two mons? Ice beam. I don't see why you would run this. (Also how is this above Soulblaze I get that soulblaze is not as good as it looks but Soulblaze is actually seen and this move is not.)
How on gods green earth is this in the same tier as 10K bolt.
Shift Gear exists. And if you are a special attacker, Shell Smash exists. And if you don't want to lose bulk, Quiver Dance exists.
HahahahahHahaHAhahAHAHHAHAHAHAHAHAH
Time for the real fun.
Tell me, what does this hit? Like actually, what does it hit. Here, I will help you, here is a list of "Good" mons that are hit by Accelerock super effectively. Oh yeah, also for some context, let's remember that a super effective Accelerock does the same damage as a neutral Espeed, so the general use of a 40 bp priority move is to hit WGs, as a STAB move, or a quad effective hit.
Mega Ray, Does the same damage as Espeed, MRay is not often WG.
Yveltal, can be WG, so this technically counts.
Articuno, more or less always MB or something like that because it is immune to almost all the OHKO moves, but it is quad effective.
KyuremB, Same damage as Espeed, and Kyurem is not often WG.
Ho-Oh, more or less the only one that is commonly WG and is also not weak to ice.
Ice? What about Ice? Well, if we take a look at Ice Shard, a move that hits a lot of mons, Ice Shard takes both Ray and Yveltal off of this list. So, we are left with Articuno, a bad mon, KyuremB, who takes the same damage from a neutral Espeed, and Ho-Oh, who is only used on hard stall and even then is rare.
So, now that we know Accelerock hits next to nothing that Ice Shard does not, let's look at the other thing that might save this move: use as a STAB move.
What rock types are good in this format? Lets take a look.
Mega Diance.
That's it.
And, you want to know a priority combo that Mega Diancie loves to use?
Pixalate Fakespeed, which hits everything that Accelerock does other then Ho-Oh.
Accelerock is complete hot garbage, and deserves zero mentions on any tier lists other then to dunk on how bad it is.
Now, to do some less targeted assaults on moves I hate, let's take about abilities! Yay!
B
Desolate land
Moody
Primordial sea
B-
Snow warning
Drought
Bad dreams
C+
Sand stream
Swift swim
Slush rush
C
chlorophyll
C-
guts
B+
aftermath
Oh no.
Anything past this point is either unreliable, gimmicky or simply outclassed by better abilities that have some same
purpose but do that thing better.
OH NO.
So, somehow all the abilities above are not
unreliable, gimmicky or simply outclassed by better abilities that have some same purpose but do that thing better.
I am going to assume that this is a formatting error, and this text should have been above B tier. But, if it isn't, then this is gonna be fun.
Desolate land: Was a niche Cteam to Water Bubble AshGren on PDon spam, and even then Water Absorb outclassed it because it was not revealed instantly.
Moody: No. Stop that. Haze exists.
Primortal Sea: Maybe on like a Scizor or a Ferrothorn? Still probably not because once again, it is revealed instantly and shows the opponent that you are clearly not WG, while something like Flash Fire can be a surprise tactic. Both are bad, but PSea is arguably worse.
Snow Warning: Tell me right now, what the hell wants to run this? What would it do for a team? Enable AVeil? Slush Rush? AVeil is not worth a otherwise useless ability, and having another mon with Slush Rush is a extremely bad idea. It's all about opportunity cost, and Snow Warning is noware close to worth those costs.
Sand Steam: Same as above, zero rock types that want the SpD boost, and other mons enabled by Sandstorm are not worth it in the slightest.
Slush Rush, Swift Swim, and Chlorophyll (Not sure why Sand Rush didn't make it): Not worth the cost. At all. Just use a scarf, please.
Guts: Do YOU want a version of Huge Power that is 50% weaker, requires a item, and makes you take chip damage every turn in exchange for not being able to be burnt a second time? Guts is here to answer this incredibly unnecessary request! Just use HP with a Lum Berry, it is better in like every way. (Also, fun fact, if you don't have STAB, even Guts Facade does less damage then HP 70 BP Facade. Just wow.
Aftermath:...Innards Out.
Anyway, that last section was probably just a formatting error, but it is still fun to talk about. Also btw, this is not a personal attack on any person who posted any of these, it is a attack on the idea, not the person behind it. Keep that in mind, I think all of you are (Probably) Cool people, some of your ideas just might not be as cool.
