Name: Grimmsnarl
Type: /
Abilities: Prankster /
Iron Fist /
Fur Coat (hidden ability) {replaced Frisk and Pickpocket}
New Moves: Arm Thrust, Enchanted Punch, Lightning Lance, Misty Terrain
(...why doesn't it get this already?), Sky Uppercut, and Trask Talk {already got Counterspell in Slate 2}
Removed Moves: [None]
Justification: I figure that for these last four Slates, I'll go back at least in my part to trying to boost at least one Gen VIII non-legendary (or pseudo-legendary) higher than it currently is even if it may not reach OU status. So far this entire time we've only boosted Alcremie, arguably Flapple & Appletun, and most recently Runerigus this way, and those were all mostly indirect boosts, which is fine. I just wanted to try to be direct again, so here we again (outside of Rapidash-Galar since we still need another Misty Terrain user).
For Slate 07, I have chosen Grimmsnarl mostly just because I've been bummed for the past couple of years about the fact that a mon with a unique typing ended up as just another Screens bot--see also: Ninetales Alola. The fact that its stats would be passable if not for its crap Defense
and Speed in addition to exclusively having the only other regular physical Fairy in Spirit Break only made matters worse. The same goes for having another exclusive move on top of that in False Surrender.
So I've tried to take advantage of what it already has logically, with the chiefest change giving the pokemon based around being covered a bunch of thick hair dense enough that can act like secondary muscles--ew--Fur Coat. So Grimmsnarl goes from being one of the Fairy mons with the worst physical Def to the physically bulkiest Fairy mon at max Def, even over Diancie and Carbink. Its typing, while having few resistances, just means it eats up Knock Off and other Dark attacks by quartering their damage, which is usable especially now that Parental Bond Zarude has been unleashed. Being one of the few mons that resist Ghost is also nice, as is the fact that both the STABs Spirit Break and Counterspell benefit quite a lot from Fur Coat too.
Not much else to say about it beyond that Iron Fist and most new moves there for those who want to try to maximize its physical offense instead, that Prankster remains despite my disliking screens since its currently one thing it can do well anyway even if mostly outclassed by fellow Screens Bot Ninetales, and that this entry would be more impactful if two more Poison moves hadn't just won. Still, what's done is done, and with Fur Coat, it at least takes those particular moves better than any other Fairy in the entire game. Yay? (Also please don't give this Misty Explosion if allowed to have Misty Terrain. Please gods no.)
RESUBMISSIONS:

(all 18 variants)
Name: Silvally
Type: (unless holding a Memory)
Ability: RKS System
New Moves: Amnesia, Blaze Kick, Bounce, Crush Claw, Dark Pulse, Extreme Speed, Icicle Crash, Power Gem, Psychic, Recover, Waterfall, Wild Charge
Removed Moves: Swords Dance {it's admittedly tempting to get rid of Explosion and Self-Destruct too, but if the player wants to throw away a version of Silvally that might actually be worth using now, they're more than welcome to do so (for now)}
Justification: I was initially considering trying to improve another Gen VIII Pokemon enough for OU until I was abruptly reminded of Memories and how bad both they and their intended holder from Gen VII were--well, are. So in turning my attention to the Disappointment Pokémon, I decided to go (a lot) further than I initially had intended, which was to just give this Recover and improve Memories and call it a day. While this seemingly has
a lot of moves added to it, literally every move here save for Crush Claw, Extreme Speed, and Recover, have been added solely for the sake of parity. I stuck with only giving Silvally a new non-Normal attacking move if it already had a strong, actual attack of that type, ignoring Multi-Attack of course. So even with all of the added new moves, all Silvally still have literally no Fairy, (real) Fighting, Grass, Ground,
OR (real) Poison coverage without the appropriate Multi-Attack or far weaker Hidden Power; a bit annoying that Silvally ended up with so many moves that can flinch, but there's only so much I can do there.
Besides that, Recover seemed obvious given Silvally can never use Leftovers and given Arceus has Recover. Quick Attack is similarly meant to emulate Arceus, but again in a lesser sense, which is more than fine given Extreme Killer Arceus Lite would probably still be too much for tiers below Ubers. Finally, while Amnesia is mostly just there for parity, it does also fit Silvally's flavor a bit, at least as Type: Null.
For all these gains, however, I think it's safest and fairest to take away at least Swords Dance, especially now that it has Recover since Silvally does actually have decent bulk. It just never got to use it before in most cases. Swords Dance might be fine even with the boost to Memories and letting it keep both Explosion and Self-Destruct, but I would rather err on the side of caution, especially after everything added. Getting rid of Swords Dance means I also am not "forced" to give this Nasty Plot, which seems like it could almost as problematic, if only because this would be able to Explode in the face of any Blisseys or Chanseys or Unaware mons attempting to wall it. (I similarly didn't give this Body Press as I was initially tempted to do since this already had Iron Defense, but even if Iron Defense was removed, Body Press might well be too obnoxious anyway due to Recover, its bulk, and being able to go Ghost.)
Despite all those changes, Silvally should still be fair if--I would hope--
much improved, even though all these choices make it go from the Disappointment Pokémon to sharing the "4MSS Pokémon" title with Mew (and technically Smeargle).

Name: Rapidash-Galar & Rapidash(-Kanto)
Type: /
&
/
{original Rapidash is now also Fairy}
Abilities: Inner Focus / Flash Fire /
Flame Body (hidden ability) &
Super Luck / Pastel Veil /
Misty Surge (hidden ability) {Run Away replaced on both and Anticipation replaced as Galar's hidden ability.}
New Moves: (Shared) Iron Head, Lightning Lance, and U-Turn
(Galar-only) Grassy Glide and Life Dew
(Kanto-only) Blaze Kick, Extreme Speed, and all the Fairy-type moves that Rapidash-Galar already has and gets.
Removed Moves: [None]
Justification: Well, after realizing that Misty Surge was once again monopolized by that Water/Fairy abomination, Tapu Fini, I checked other Fairy (and Ice) mons to see if any would be appropriate and worthwhile users of Misty Surge with Weezing-Galar losing it since it makes sense to have a replacement when all other terrains still do. In short, while many mons could reasonably get Misty Surge within their flavor, without being able to touch mons' stats in this Pet Mod, most of those replacements would all still be both outclassed by Tapu Fini and mostly mediocre mons in general, especially since Fairy Terrain is (thankfully) the weakest terrain. As such, I decided to focus on Atk stat since that's Tapu Fini's second weakest stat, and the viable non-Mega, non-legendary choices thereafter were few. Rapidash-Galar seems like the ideal candidate of those left, not just because it is the fastest (though that helped) but more because it is a mon held back more by its mediocre movepool and crappy abilities than its power-crept stats; Rapidash-Kanto just got brought along for the ride and made Fairy along the way since it is technically a unicorn too, just not as majestic as the Galarian form, so no Misty Surge for it. (Its horn either looks like its other ear in the SM sprite or weirdly just doesn't exist.)
Since we can fix both movepool and ability stuff here, I've attempted to do so fairly, even if that means--sigh--adding a pivoting move so that Rapidash-Galar legitimately has niche as a Misty Surge setter over Tapu Fini unlike Weezing-Galar, who was just bad at using it. The weirdest looking additions are probably Rapidash-Galar's two new exclusive moves, but they're both related to its Pokédex entries as itself and as Ponyta-Galar as well as real life unicorn myths, which apparently Game Freak researched well for accuracy. Given said myths are why Pastel Veil exists at all, it seems a shame to get rid of it despite Misty Surge largely outclassing it in Singles. So since Anticipation currently still sucks only slightly less than Run Away, that was easy to replace too. Pastel Veil isn't completely useless in Singles, however, since it plays well with other terrains, which is good since Rapidash-Galar now plays well in all terrains between its two types, access to Grassy Glide (which I wouldn't have given it at all if Dubwool didn't for some reason get it), and Lightning Lance. Granted, you can also use Super Luck for playing with other terrains, but that's mostly there because unicorns in myths were thought to be rare & signs of good fortune among other things and because Rapidash-Galar's Pokédex entry weirdly talks up Psycho Cut of all things. So now you can get guaranteed crit STAB Psycho Cuts with Super Luck and Scope Lens (or the less classy Razor Claw). [/new meta]
Finally, Rapidash-Galar has Inner Focus solely because I wanted to try to replace the useless Run Away with an ability it might have realistically gotten instead, meaning I confined myself to Gen III abilities. Inner Focus just fit the most of the Gen III abilities outside of the overpowered Speed Boost, which would rightly never be allowed. Inner Focus at least blocks Intimidate now too in addition to the dumbness that is Flinching in general, so it does have an actual use. Will either of these mons will be JolteMons OU material even with all the changes though? I doubt it, to be honest, but they'll already at least no longer be completely there (or in much lower tiers) with what they have been given now if they are chosen.

= Boomburst, Moonlight, U-Turn {already got Counterspell from Slate 2}
Removed Moves: [None]
Justification: I tried to keep the Eevolutions true to being their mono-typed selves, which meant giving them all Adaptability out of the gate, which should be fine on all of them--even Jolteon--given how much they've been power crept and given Glaceon is rather slow. That also helped to make sure that they all had one usable ability. Otherwise, I made sure they all got four moves, even half of those tended to be taken up by a pivot move--ugh, what have I become?--and healing outside of technically Jolteon, who arguably got buffed the most anyway.

= Likely to still be outdone by other Water types just because so many exist, but it can at least be a support mon that doesn't worry about status now with pivoting, hazard removal,
and Knock Off thanks to Natural Cure. (I was tempted to give it Water Compaction or Rain Dish initially.)

= Got perhaps the most far-reaching buffs between benefitting the most from Adaptability arguably, getting Rapid Spin
and Spikes, and being able to clean up nicely late-game with newfound Hex even before the addition of Buzz Off.

= Easily the Eevolution that needs the most help besides, weirdly, maybe Espeon, which is why they fought back and forth for Fur Coat for a long while. It ended up getting that instead of the more appropriate Fluffy that it initially got when Espeon had Fur Coat mostly because Flareon cares about non-contact moves way more while most of the stuff that hits Espeon super-effectively on the physical side is contact--same goes for the few things it resists, i.e. Fighting moves and Zen Headbutt. (Briefly considered giving it Speed Boost instead, but that didn't solve any of its actual problems, especially since at +1 Speed it's still slower than 110 Speed mons. So it just got First Impression instead.)

= See above. It mostly just got more coverage otherwise and U-Turn instead of Teleport since Slowbro and Slowking and other far slower things would still use Teleport way more. It has more coverage and technically far more bulk now, which are both the things that made it arguably drop off so hard even if it has to not use Magic Bounce to achieve the latter.

= Originally gave this Poison Heal, but that kinda obviates Sticky Hold (since you can pretty easily just switch into Knock Offs once Toxic Orb activates), so I just gave it
Immunity Merciless. Not much to say about it otherwise outside of that if Immunity buff wins, then I would prefer Immunity over buffed Merciless; it's just that the buffed Merciless is guaranteed to exist at present.

= Still gets switched on by every Flying type in the world and probably ends up the least if this wins but the change to Leaf Guard doesn't, but it at least won't lose momentum now and doesn't get auto-walled by every grounded Steel-type too.

= Likely the second best Adaptability user of the bunch since it officially got Freeze-Dry this gen. Otherwise I couldn't do much to change the fact that it's a slow Ice mon, so I focused more making it didn't also outstrip Vaporeon as a Water mon too given Meltdown and given the aforementioned Freeze-Dry even if it's basically still "Vaporeon: But Angwy! Edition". That's more why Vaporeon got Knock Off than anything else, really.

= Last but not least, we get to the still most recent Eevolution mon, which is still one of the better ones just because Fairy type is a bit busted. It lost Pixilate due to Adaptability mostly rendering that redundant, but at least Pixilate still exists on Gardevoir-Mega whose still using it well unlike, say, Long Reach. Additionally, the loss of Pixilate both lets me safely give it Boomburst (even with Calm Mind given Toxtricity exists) and as well make it more likely we finally get a replacement Misty Terrain setter even if this far more likely to be outclassed by Tapu Fini still as a Misty Terrain setter than Rapidash-Galar. Still, rip physical Sylveon sets. Sorry,
Scorbunny.
