Also a few thoughts on the VR:
RISES:
A to S
The best mega right now. It has an incredible typing, naturally checks like half the meta, never dies, and is an incredible rocker. Dual 100 BP STABs, one of which paralyzes everything, makes it a nightmare to switch into if there isn't a hippo. Fits on virtually any team composition that isn't hyper offense (this thing is a menace on stall) and just generally always generates extreme utility throughout the course of a match. The strongest offensive waters are also weak to one of its STABs, so it doesn't even have common offensive counterplay that can come in on it. This shit unboosted haxes through physdef clef and its not even a wallbreaker ffs
A- to A
The addition of Flip Turn alongside natural access to EQ for Coal means it can at least pivot around every traditional water stop (sans shit like gastrodon/toad) while Aqua Jet is incredibly strong priority for various fastmons (especially Volcarona). Suffers from all of the helmet pivots, but at least it only loses 1/6th of its HP compared to 1/2 like Ursh so it could be worse. Consistent offensive mon overall.

B+ to A-
It suffers a bit thanks to its garbage bulk but the departure of Cinderace was a great indirect buff and it resists the best priority in the tier (Drednaw's Aqua Jet). Very few safe switchins, and that ones that are (like pex) will eventually be broken by defense drops. If paired with other pivots it's demonic to face.
B+ to A-
Phydef Helmet tang hard stops Drednaw and punishes the U-Turn spam going around, has Knock for post-sleep utility, and can even catch greedy Coals with EQ/Focus Blast on the switch. More raw bulk to sleep Sandaconda is also good. Regen grasses in general are great and tang has enough positives over Amoong to be on the same tier imo.
B to A-
Fills the gaping hole left by Magearna to be the offensive Duraludon check we all love. Specs also appreciates Urshifu forcing Mandibuzz to go physdef and CC still nukes pink blobs.
C to B-
This thing is flames and has a banger matchup against TR if you want to be CTing bitch. Poisons the Coal every time
DROPS:
S to A+
Still a godtier mon but not the best mega nor is it on par with the other S tiers in terms of splashability. Its main flaw is that the waters it abuses on paper all have some way to get around Desolate Land while Coal at best can just spam spikes. Pex poisons it, slowbro sets up future sight or teleports out, drednaw clicks EQ, etc. Not to mention Coal's extreme hazard weakness means it either demands great hazard control or only comes in 2-3 times a game. Overall still a menace but I don't see it being an S-Tier wallbreaker (easy to wall for most teams) nor an amazing utility option even if it is a consistent spiker.
A+ to A
Its poor offense matchup is enough to keep it from being on par with stuff like Duraludon, Coal, etc. Feels more on par with Drednaw. Hates Sandaconda.
A+ drop to A-/B+
This thing isn't really that great imo. Rocky Helmet pex is the pex set, and this thing still loses against that long term. The other bulky water of choice, Slowbro, also beats it for obvious reasons. Its a fine offensive pivot but as a stallbreaker I can't see it being the best option and I honestly just don't see it enough to warrant the A+ ranking. Once Rocky Helmet goes out of fashion maybe waterbear can come back.
(Appletun)
A to A-/B+
This mon is still pretty great, but it suffers from the severe competition for the megaslot- This mon is really, really easily replaced by Amoong/Tang, whereas stuff like Sandaconda/Coalossal occupy an entirely unique niche. The Dragon typing isn't doing it a whole lot of favors either, with a neutrality to Fire being pretty useless when Fire attacks are either Coalossal's Flare Blitz or coverage from mons that now/already hit you supereffectively with their STABs (Dragapult, Volcarona, Hydreigon) and the other resistances being redundant with grass. Still has the edge over the other regen grasses thanks to offensive pressure it exerts, but I just don't think its good enough to justify losing your mega slot for it. Should be A- with the other regen grasses at best, B+ for the opportunity cost imo.
A to B+
This thing hates the prominence of Coal/Drednaw. Only top tier mega it even scares out is Duraludon. 2 new hard counters means the moth is worse off.
B+ to B/B-
Never used this myself but I've played against it and I've never had trouble. It's slow as all hell and its bulk is still subpar. Defensive typing isn't particularly relevant outside of Urshifu, who can still 2HKO with Blow if adamant and Butterfree is just max HP (can't imagine going physdef lol). And if rocks are up, lol. Needing 2 QDs to actually outspeed everything also sounds not great. Not even good in the stall matchup because of chansey+ditto. I'm sure it has its moments but it doesn't look on par with stuff like Chansey/Kyurem. I retract my statement sleep+QD is some high-key stupid shit
B+ to lower
Sounds like a cool Coalossal check until it gets burned on the switch. Also this is Rillaboom meta and Sandaconda is kind of really good. Idk where to drop it because I've never seen nor used it but I fail to see its merit.
B- to Shadow Realm
This thing is ass lol. Coalossal/Drednaw is there if you want a mega that spams a nuclear physical attack and they both have leagues more defensive and offensive utility. The biggest thorn in this guy's side though is definitely Urshifu, though. Banded Wicked Blow hits harder than False Surrender, and Play Rough hits nearly as hard at the cost of, well, hurricane accuracy. No clue why this thing would ever be worth the risk, if you land all your hits you get a slow, weaker Urshifu that kind of beats clef better. If you miss your hits, lol
C to Shadow Realm
Originally nommed this to C on the voting sheet because I thought it was part Steel fsr. If it was part Steel, it would have been a fire Magearna counter that could mess around with a lot of passive mons. As a pure poison, however, I fail to see what this brings to the table. At least NGas Weezing also counters Urshifu, this thing gets gutted by Wicked Blow. Sets spikes but so does Coal.
