1. why is Calyrex banned with its insane speed it basically requires iron ball and even then it might still be too fast and it is not really bulky
2. Iron ball seems crazy good basically a better scarf in tr
1. Calyrex-S may not be "really bulky", but it can still switch into mons like Hatterene, Dondozo, and Clodsire and fire off a mighty attack or, at least in versions of this meta where Trick Room works, use Trick Room and outspeed everything for 4 turns. The Trick Room part may be why Calyrex-S started off banned - mighty but slow attackers without priority such as Chi-Yu, Annihilape, and Walking Wake have felt balanced so far in my testing.
2. Yeah, in my testing, Iron Ball and the Power items squeeze out pretty much all other items for offensive mons with decent speed tiers, to the point that Guts mons shouldn't have Flame Orb and Gluttony mons get outsped by too much if they use Berries. Being open and vulnerable to hazards is worth it when the reward is hitting hard first.
On a more optimistic note, Wave 3 of promising Pokemon!
:SV/Skeledirge:
Skeledirge @ Heavy-Duty Boots
Ability: Unaware
Tera Type: Water
EVs: 248 HP / 8 Def / 252 SpD
Sassy Nature
IVs: 0 Atk / 0 Spe
- Torch Song
- Will-O-Wisp
- Slack Off
- Shadow Ball / Earth Power
Meet the meta's best spinblocker. With Torkoal as the best spinner in the meta, and Avalugg and Forretress at least having great speed tiers, Skeledirge spinblocks them all and tanks their attacks. Torkoal can still go for breaking through its checks, but Boots on Skeledirge make that job harder by nullifying Rocks on Torkoal. Skeledirge also does well against Hatterene.
:SV/Donphan:
Donphan @ Iron Ball
Ability: Sturdy
Tera Type: Ice
EVs: 248 HP / 252 Atk / 8 SpD
Brave Nature
IVs: 0 Spe
- Rapid Spin
- Earthquake
- Ice Spinner
- Curse
A meta where Donphan is outright better than both Paradox Donphans - who'd have thought? Donphan has a decent base 50 Speed and is among the better Rapid Spinners in the meta (it notably breaks Skeledirge and the one guy who brought Gholdengo). Like a lot of Curse users, it threatens to sweep with enough boosts.
:SV/Latios:
Latios @ Choice Scarf
Ability: Levitate
Tera Type: Fairy
EVs: 248 HP / 252 SpA / 8 SpD
Quiet Nature
IVs: 0 Spe
- Draco Meteor
- Flip Turn
- Shadow Ball / Luster Purge / Psychic Noise / Surf / Weather Ball / Aura Sphere
- Trick
Actually, at base 110 Speed, Latios might be the viable mon with the highest base Speed in Twisted Dimension. Unlike Latias, Latios gets Flip Turn and therefore can slow pivot. Trick-Scarf is still a mean thing to do - pray your opponent has no slow pivots that can absorb the Scarf. Shadow Ball hits switch-ins like Hatterene, Solgaleo, and Jirachi decently hard, but it thuds into Kingambit.
:SV/Moltres:
Moltres @ Heavy-Duty Boots
Ability: Flame Body
Tera Type: Fairy
EVs: 248 HP / 8 Def / 252 SpD
Calm Nature
- U-turn
- Roost
- Flamethrower
- Scorching Sands
Moltres is among the tankiest Torkoal switch-ins - it resists Fire and Fighting, 4x resists Grass, and is immune to Ground, and it has reliable recovery. Moltres takes advantage of Torkoal by slow pivoting or smacking it super-effectively with Scorching Sands, a move with Scald's burn chance. Moltres also tanks hits from Enamorus-T, Hatterene, Lurantis, Glastrier, and more.
:SV/Zapdos:
Zapdos @ Heavy-Duty Boots
Ability: Pressure
Tera Type: Electric
EVs: 248 HP / 252 Def / 8 SpA
Bold Nature
IVs: 0 Atk
- Roost
- Volt Switch / U-turn
- Thunderbolt
- Hurricane
Moltres's partner in the Legendary Birds trio is among the more resilient ways to naturally break Dondozo. It also switches into Fighting-types fairly well and Ground-types fine. Zapdos is also a decent slow pivot, just like Moltres.
:SV/Samurott-Hisui:
Samurott-Hisui @ Power Anklet / Focus Sash
Ability: Sharpness
Tera Type: Water
EVs: 248 HP / 252 Atk / 8 SpD
Brave Nature
IVs: 0 Spe
- Ceaseless Edge
- Aqua Jet / Sucker Punch
- Flip Turn
- Knock Off / Sacred Sword
It turns out that Mr. Spikes is eternal. Samurott-H can switch into Kingambit, Incineroar, and more and set up Spikes that Hatterene can't Magic Bounce away. Samurott-H can slow pivot, use priority, remove Boots from opposing mons, or truly scare away Kingambit with Sacred Sword. Focus Sash is actually a decent choice so Samurott-H can lead against mons that can OHKO it through its added bulk, such as Glastrier (with Close Combat) and Torkoal (with Solar Beam).
:SV/Corviknight:
Corviknight @ Power Bracer
Ability: Mirror Armor
Tera Type: Flying
EVs: 248 HP / 252 Def / 8 SpD
Relaxed Nature
IVs: 0 Spe
- Curse
- Roost
- Iron Head
- Body Press
Yeah, Corviknight can Defog and pivot, but opponents also need to fear it as a Curse user like they fear Swords Dance Gliscor in OU. Iron Head is used as an early-game mid-ground that hits both Glastrier and Hatterene super-effectively. Speaking of Hatterene, Mirror Armor is used to wall that mon better by bouncing back Mystical Fire debuffs. Corviknight can squeeze in Taunt to ward off stall better. Skarmory is capable of a similar Curse set, squeeze in Whirlwind to phaze out switch-ins like Dondozo, and set hazards instead of use Curse. Skarmory is a poor Hatterene check at best, though.
