More Xatu boosting, at level 40 it achieved a clean set up an sweep vs Juan, no healing items, outspeed everything including Kingdra. Set up CM to +6 and Sun vs Whiscash taking 50% total. Vs Wally (lv 41, 42 after Garde) it came in to tank Gardevoir and an incoming Future Sight after Banette went down and set up to +3 without issue to outspeed and KO with Psychic (also OHKOd Delcatty).
Definitively proving it's worth and actually making a case for C, E4 should determine D vs C and sorting this will likely be my focus.
Punchshroom you originally nominated to E, I'm curious your thoughts given Xatu's very strong performance for me so far.
If I had the same kind of optimism you have, I'd be making nominations like Spoink to B, Girafarig to C/B, and not harshly bashing Ninjask/Shedinja every time someone brings them up.
The main takeaway here is that Calm Mind is a stupid good move, and I don't doubt that even something like Chimecho can do most of what Xatu can pull off here (Chimecho has an equally strong Psychic and more bulk than Xatu btw, while also not being weak to Ice). I'm also expecting you to change your tune on Xatu
real quick once you take it into the Elite 4. Calm Minding is something that a large majority of late-game Pokemon can do (even Banette could have done it), so Xatu needs to be pretty exceptional to justify this investment. Compare some of the Calm Mind competition that it has in the same/adjacent areas:
- Psyduck can be caught at very high levels, up to level 35, meaning there is no need for it to play catch-up. Golduck can contribute against Tate&Liza, use its Water & Ice resistances to set up on Wallace/Juan/Glacia and smack them with boosted Psychics (its best neutral attack), and of course Ice Beam lets it barrel through Drake.
- Girafarig's access to Thunderbolt lets it sweep the Water bosses with less Calm Minds under its belt than Xatu, and its Ghost immunity allows it to set up against Phoebe as well. As an added insult, Girafarig doesn't even need to level up and evolve to immediately hold its own like Xatu does. In fact, I think there's hardly any instances where Xatu would outperform Girafarig outside of being able to SolarBeam Tate&Liza, since Giraf is superior in the other boss matchups as well as route trainers (Thunderbolt > SolarBeam for route trainer coverage).
- Banette is a bit too frail, both in terms of bulk and resists, to reliably set up Calm Mind without eating through Hyper Potion reserves, but once again, Thunderbolt access is pretty huge and does give it hope of better contributions against the Water bosses. Shadow Ball also smacks Tate&Liza and Phoebe pretty hard too, though obviously Banette isn't expected to beat down more than 1 Ghost at a time, or just risk getting outsped by her own Banettes. Still, better track record than Xatu in any case.
- Absol faces the same fraility issues that Banette does, but having
BOLTBEAM alongside Calm Mind is nothing short of a godsend if you do choose to go this path. Most people would probably prefer the Swords Dance + Shadow Ball route, but even then I would consider Absol an overall superior investment for the Calm Mind TM.
Even disregarding the competiton, I've
already pointed out Natu's own shortcomings (especially in the E4 matchup) numerous times. Natu already suffers from being a lategame mon, but I expect it to do better than just being good for the remaining Gyms while struggling/flopping against almost the entire E4 to warrant D Rank in the first place, much less nom it to rise.

C to B
"Discount Swampert" is still pretty damn great, especially when it starts off with Surf, EQ, and the Ice Beam TM the moment you get it, though it needs to be Good Rodded at its highest level of 30. Barboach has pretty much no losing matchups outside of the super telegraphed Grass-type attack (Sidney's Shiftry is not one of these btw), and nearly any boss that risks overpowering Whiscash can be stopped by Amnesia. It's not particularly powerful but the power of its attacks more than make up for this, and from my experiences Whicash makes for an even better Amnesia user than Swalot in all the battles that matter. Unfortunately it misses out on Wattson and Flannery, but it's still plenty good for the remaining matchups in the game.
D to E
Rhyhorn has been getting a lot of flak lately, but at least it has access to two serviceable STABs in Rock Blast and Dig. Phanpy is a one trick
pony elephant by comparison, being
largely relegated to non-STAB coverage SINCE DONPHAN DOESN'T EVEN GET DIG while not boasting any matchups where it outperforms Rhyhorn. Even in Victory Road, where Rhyhorn could have either already evolved or start training there, Rhydon has an easier time than Donphan against more trainers due to its superior physical tankiness and extra resistances to Normal, Fire, and Flying, with relatively few opponents that punish Rhydon's typing that wouldn't be hurting Donphan as well. All in all, I don't consider Phanpy's far earlier evolution level in exchange for being even more limited and linear than Rhyhorn/Rhydon to be remotely valuable. Its only saving grace is its favorable matchup against Steven's Metagross, but that's hardly worth the payoff of being average at best to being deadweight most of the time (especially its pre-EQ period) for so long.
C to B
Between Swords Dance and the aforementioned Calm Mind, as well as having terrific coverage moves to complement its boosting options, few Pokemon can boast this sort of offensive versatility. This gives the Absol user a good amount of freedom in how they want to run their Absol, so I believe a rise would be warranted.
