Will edit over time, sheet is also updated with last slates mons

Name: Soul Dew
Effect: If held by a Latias/Latios, its Sp. Atk and Sp. Def are 1.5x.
Removable: Unchanged
Fling Power & Effect: Unchanged
Justification: Unnerfed Soul Dew reintroduces the Latis as strong, viable mons in the meta that (I believe) were not overbearing especially considering the slower speed tier in the meta. The typing is also appreciated as both a Dragon-type to resist moves like FishBeakV-create and a Psychic-type to resist stuff like Lumina Crash. Latias should be a solid defensive presence while Latios will look to be a strong wallbreaker, though it will compete with UNecro with its superior speed tier. Both also have pretty favourable imposter matchups.

Name: Calyrex-Shadow
Type: Psychic / Ghost
Stats: 100/85/80/165/100/150 -> 100/85/100/135/100/160 (+20 Def, -30 SpA, +10 Spe)
Justification: 160 speed gives it a relatively unique speed tier, giving it a defined niche as a blazing fast potential revenge killer compared to MGar who is stronger and MMY who is more versatile. 160 speed also means it can run Modest, still outspeed MMY, if the Zac-c outspeed is not necessary. 135 special attack heavily cuts its offensive potential, but retains its revenge-killing potential by OHKOing MGar with unboosted Judgment/Astral. Its defense is buffed to give it some more survivability, as retaining 680 BST isn't that bad.

Name: Calyrex-Ice
Type: Psychic / Ice
Stats: 100/165/150/85/130/50 -> 100/175/140/65/140/60 (+10 Atk, -10 Def, -20 SpA, +10 SpD, +10 Spe)
Justification: Wanted to adjust Caly-I since Caly-S is adjusted, though their stats aren't actually counterparts to each other so this might be treated as a different sub (but also means I have more freedom with stats). 175 Atk lets it always kill Zyg-C from full with Adamant GLance, 60 Speed means at +2 neutral it outspeeds Zac-C, 140 SpD allows it to always live two MMY LoR, Def is dropped to match SpD to try to help not overtuning it, and it doesn't miss out on major benchmarks.

Name: Mewtwo-Mega-Y
Type: Psychic
Stats: 106/150/70/194/120/140 -> 106/140/70/184/120/140 (-10 Atk, -10 SpA)
Justification: MMY benefits a lot from new toys, and was just pretty overwhelming in the first place, only held back somewhat by its poor offensive typing and Zacian-C's speed tier. These minor changes are more conservative nerfs to reduce its effectiveness

Name: Mewtwo-Mega-X
Type: Psychic/Fighting
Stats: 106/190/100/154/100/130 -> 106/180/100/144/100/130 (-10 Atk, -10 SpA)
Justification: Same justification as above, both tweaks make them weaker as mixed breakers, which also opens up more of a niche for Deoxys-A

Name: Latias-Mega, Latios-Mega, Latias, Latios
Type: Dragon/Psychic
Stats: 80/100/... -> 100/80/..., 80/130/... -> 100/110/..., 80/80/... -> 100/60, 80/90/... -> 100/70/... (+20 HP, -20 Atk)
Justification: 80 HP makes these things have worse bulk than expected, with notably Mega Latias getting 2HKOed by unchanged PDon V-create and Band MMX Close Combat. They don't (and won't esp with Soul Dew) use their attack stat anyways.
Name: V-create (readjust)
Accuracy: unchanged
Power: 120 -> 150
Category: unchanged
PP: unchanged
Effect: Super effective multiplier 1.5x -> 1.2x
Z-Effect (if a Status move): unchanged
Priority: unchanged
Flags (ex: Contact, Sound): unchanged
Type: unchanged
Pokémon With This Move (optional): unchanged
Justification: Last slate's numbers were made with a potential PDon nerf and unrestrict in mind, so V-create was overnerfed. A readjustment in base power means PDon is not completely screwed on its main STAB, as 150 BP is enough to OHKO threats like MMX. This is why 150 + 1.2x was chosen over 140 + 1.3x
Name: Shell Smash (resubmit)
Accuracy: -
Power: -
Z-Effect: Unchanged
Category: Unchanged
PP: Unchanged
Effect: No longer provides +2 Spe.
Priority: Unchanged
Flags (ex: Contact, Sound): Unchanged
Type: Unchanged
Justification: Shell Smash before ban is pretty much the best boosting move, providing the most stat changes for offenses and speed. This change, by removing the speed, makes it a very specific boosting option for certain mixed attackers as otherwise its outclassed by Swords Dance and Tail Glow. The removed speed also increases the risk of the defenses drop, as the Pokemon is now more vulnerable to retaliation.
Name: Moongeist Beam + Sunsteel Strike + Photon Geyser
Accuracy: Unchanged
Power: 100 -> 90
Z-Power: Unchanged (we could do 180 -> 175 but Thousand Arrows has 180 (and Land's Wrath has 185) so who cares)
Z-Power: Unchanged for signature Z-moves as well
Category: Unchanged
PP: Unchanged
Effect: Unchanged
Priority: Unchanged
Flags (ex: Contact, Sound): Unchanged
Type: Unchanged
Justification: Moldy moves are extremely metagame defining, as they dictate what FurScales users are good, since a good Scales user pretty much has to resist Moongeist while FC has to resist Sunsteel. These nerfs also provide a nerf to Zacian-C, and an alternate angle to nerf stuff like Gengar-Mega instead of nerfing Astral Barrage. Photon Geyser didn't really need to be nerfed but consistency

Type: unchanged
Justification:
Name: Neutralizing Gas (Resubmit)
Effect: New effect: Opposing Pokemon's moves and their effects ignore their own ability.
Permanent: No
Ignoreable: Does not matter
Justification: Neutralizing Gas needs a rework. This change makes it a situationally powerful ability on defense. It can suppress the power boost from abilities like Adaptability, Tough Claws, Libero, Gorilla Tactics, Sheer Force. Stronger still is suppressing -ate abilities, and it can also cripple Magic Guard Pokemon with recoil damage. Note that it cannot suppress the damage boost from Desolate Land and Primordial Sea as the power boost comes from the weather. The drawback here is that it does not provide as much of a defensive buff as FurScales.
Name: Sword of Ruin, Beads of Ruin (Resubmit)
Effect: Unchanged, but 0.75 Def/SpD -> 0.8 Def/SpD.
Permanent: No
Ignoreable: No, but does not matter I think
Justification: Currently these abilities provide an effective 1.33x boost to all attacks of that category, at the cost of announcing. This makes it the best boosting ability for non-mixed sets if the element of surprise is not necessary. This number adjustment makes them effectively 1.25x boosts, which is lower than most boosting abilities, but they still have the unique bonus of boosting every move.
Name: Arena Trap
Effect: Opposing grounded Pokemon that switch-in lose 1/6th of their maximum HP. (Does not affect Flying-type, Levitating, Magic Guard, Air Balloon or Heavy-Duty Boots)
Permanent: No
Ignoreable: No, but does not matter
Justification: Arena Trap being a trapping ability is broken and banned. This change reworks Arena Trap as an effective way to force chip damage onto opposing Pokemon without Magic Guard. 1/6th is chosen as the damage inflicted by 2 layers of Spikes but this value can be easily adjusted.
Name: Neuroforce
Effect: 1.25x -> 1.5x
Permanent: No
Ignoreable: No, but does not matter
Justification: Neuroforce is basically outclassed always. This change makes it an appealing option for mixed sets with a wide super effective coverage that do not want Sheer Force, Magic Guard, or Pure Power. It also buffs Ultranecrozium-Z NDM/NDW

Justification: Same justification as above, both tweaks make them weaker as mixed breakers, which also opens up more of a niche for Deoxys-A




Name: Latias-Mega, Latios-Mega, Latias, Latios
Type: Dragon/Psychic
Stats: 80/100/... -> 100/80/..., 80/130/... -> 100/110/..., 80/80/... -> 100/60, 80/90/... -> 100/70/... (+20 HP, -20 Atk)
Justification: 80 HP makes these things have worse bulk than expected, with notably Mega Latias getting 2HKOed by unchanged PDon V-create and Band MMX Close Combat. They don't (and won't esp with Soul Dew) use their attack stat anyways.
