Big OU Players
These are the Pokémon that most likely would not need many changes (if any at all) to be viable on day 1 meta. Tried to order from most likely to be good to most niche ones.
Reasoning: self-explanatory
Resoning: Very hard-hitting Fires on a meta with not many bulky Waters available. Darm is the better out of the two but I'd still expect both to be used.
Reasoning: Its one out of two Water mons with recovery available. Pretty bulky on its own right and has good utility in WoW and Strength Sap
Reasoning: Easily the best Electric available, very good typing + wide movepool. Might even be a bit too good with Plot, but we'll see.
Reasoning: Similarly, Tornadus is easily the strongest offensive Flying we have available. Relying on Hurricane is unfortunate though.
Reasoning: Good Rocks setter and Pivot, mostly
Reasoning: Generally really bulky Psychic that can either be really sustainable with Regen or be a wallbreaking force with Life Orb. Might struggle with the presence of a decent amount of Darks running around though
Reasoning: Notably fast hard-hiting dark w plenty of coverage available. Not much depth to why i think this would be good, but it does share competition with Hydra.
Reasoning: Hits insanely hard and has great utility in First Impression, but Hustle is also fairly unreliable
Reasoning: Our only Weather Setters available, and while they both have downsides, they could potentially be really good enablers. Gigalith had the edge here as the Sand abusers available are much stronger than Snow's, but I think both could end up seeing play.
Reasoning: Our second best Electric available, believe it or not. Nowhere as relevant as Thundy, but I believe Sticky Webs already gives it a valuable niche.
Miscelaneous stuff that I think could be easily viable with a few buffs
Just some mons that I feel wouldn't need that much of a major rework to be made viable, rather just some small tweakings
Potential Nerf Radar
Reasoning: Whether Fairies are real or not, Offensive Dragons are a very strong presence in this meta. There are not many Dragon resists - Other than Whimsicott, only really Steels take them on (and even so, the only Steel with recovery is Ferrothorn and both of these mons get coverage to hit most Steels very hard). Both of them may be on the nerf watchlist.
Reasoning: This one depends entirely on how we wanna handle weather. If we do permaweather, Excadrill would need a nerf.
DEFINITELY on Nerf Radar
Reasoning: lmao
Reasoning: Shortage of bulky Waters, no Heatran and generally not many bulky Fires either
Reasoning: Genuinely cannot find a single mon that can safely switch into this dude
