Ok so i have said this before but i do think im going to say it again, but with a bit more reasoning. I think pure sashes (this is what ill be refering to the combo of Heavy-Duty-Boots + Focus Sash) should be either claused to 1 of these per team, or claused to not be allowed at all.
I'm going to show a few examples on why i dont think it'd be very fair.
Example 1: In a meta where you can have multiple abilities you'd think pokemon like dragonite might run HDB, Multiscale, and Inner focus, to give it hazard immunity, good bulk to setup with, and it wouldn't be slowed down by pokemon like intimidate landorus-therian. Or it could ditch multiscale, something id consider to be perfectly fine, since with how offensive the meta is going to be, with item/ability stacking being very good, there would be a good amount of breakers being able to take care of multiscale themselves. Or it could Forgo this to simply use a Pure Sash, live anything, and get a single KO before getting killed by another pure sasher, perhaps even something as unusual to run sash on as gholdengo, or great tusk.
Example 2: For this one im going to take one of user HiZos sets (see below
One move wonder sets could potentially be nigh unwallable in certain situations, like if you have an stab without a common immunity you can just pile high with strong items that bolster your stab and just attempt to break through.
There already are some examples in the thread but here are more:
Meowscarada @ Life Orb
Ability: Choice Band
Tera Type: Grass
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Flower Trick
- Choice Scarf
- Miracle Seed
- Meadow Plate
Still walled by skarm and corv, but you do crit through most resists anyways
Basculegion (M) @ Adaptability
Ability: Swift Swim
Tera Type: Water
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Wave Crash
- Choice Band
- Splash Plate
- Mold Breaker
Needs rain to function but Wave Crash from Pokebilities Basculegion would kill everything including itself
Yanmega @ Throat Spray
Ability: Speed Boost
Tera Type: Bug
EVs: 4 Def / 252 SpA / 252 Spe
Modest Nature
IVs: 0 Atk
- Bug Buzz
- Silver Powder
- Choice Specs
- Tinted Lens
1.5x from throat spray needed but if you can dodge rocks and hold your own for a few turns you can outspeed everything
Indeedee (M) @ Twisted Spoon
Ability: Psychic Surge
Tera Type: Psychic
EVs: 252 SpA / 252 Spe
Timid Nature
- Expanding Force
- Choice Scarf
- Choice Specs
- Terrain Extender
Idk if Psyspam is good but you never know, however being able to randomly tack on an extending item seems broken enough
So if we take their meowscarada set, replace the choice band with overgrow, for i believe the offensive choice items have been banned, then you may have a similar damage output after taking maybe a corviknight u-turn? Then youd have free reign to click overpowered flower tricks until you slam into a pure sash great tusk. It rapid spins away your hazards that were meant to chip down pokemon, and stop focus sashes from ruining the sweep (so much for those stealth rocks).
Im going to guess my examples have gotten through to most of you, but there is probably going to be another side effect; the team quality. Normally, a team would require a priority pokemon to stop a single pokemon from sweeping your entire team. But i do think that there would be some, albeit mostly low ladders players would be the worst case, cases of players becoming to complacent with pure sashes stopping sweeps to the point where if they tried another metagame, theyd equip many of there pokemon with focus sashes, assume that they're safe from any form of setup sweeper, and get destroyed by a sweeper, the only difference between this meta and BMM is that there were hazards up; ones that actually did something.
Overall i think it wouldn't be a very healthy thing to have in a metagame, which is why im requesting its quick ban.
TLDR: All of these big damage rolls you guys want so badly would get destroyed by a random pokemon using HDB and Focus Sash.
