Silvally-Ghost
Mega Sableye is a fraud - if you're looking for a generic bulky Ghost, this is the first mon that should come to mind. 95 across the board might not sound that impressive, but that's damn near mythical; In fact, if I've run my rough numbers right (which you should never trust but if), factoring in natural typing and stats plus averaged move pulls, this is the single bulkiest base Pokemon in Metronome battle.
I think I can kind of support this as well for what it's worth, because I remember
fwqef telling me a similar result about how Silvally-Ghost ranked defensively back in 2019, even pre-Gen 8 when Silvally formes were still item and ability locked. Now the exact details elude me, but it does sound about right and I do still have a fond opinion of it looking back. Plus it has the niche of being naturally immune to type changes, though now I suppose you can have any single mon pull that off with Tera. But yeah, this post was a pretty nice shout in hindsight looking ahead at June's usage stats..
While the Pokemon Presents is still to come later this month, in other Smogon news, the new CAP 36 (Ramnarok, officially named just hours ago) has settled upon a stat spread (or two), though only its Fire/Ice forme can be used because the other one is Fire/Steel and banned, which is a shame because they are both 600 BST and the unusable one is actually fairly bulky with a 110 HP / 63 Atk / 104 Def / 104 SpA / 134 SpD / 85 Spe spread.
Instead, the usable Fire/Ice forme has 110 HP / 63 Atk / 85 Def / 134 SpA / 54 SpD / 154 Spe, ramping up Speed and Special Attack while sacrificing a lot of Special Defense and some Defense, kind of like Shaymin-Sky but more lopsided. In terms of where this stands relatively, 154 Speed notably puts it as the 4th fastest option in the game at least according to a quick teambuilder sort. Not that having really high Speed and leaning towards Special Attack is that great or demanding of an archetype to join, but it at least has pretty high HP compared to its competition which mostly doesn't even hit 100+ HP.
In terms of other base Fire/Ice types, the only other one for reference is Darmanitan-Galar-Zen and its 105/160/55/30/55/135 spread, which is actually kind of similar but more minmaxed and arguably better by focusing on Attack? Not that being Fire/Ice is a great defensive typing to work with either over being a pure Fire-type, but on the offensive side, you do get both STAB boosts even post-tera, so you could double down on tera Fire and hit a Grass type really hard? I wonder if that actually does anything relevant.
252+ SpA Tera Fire Ramnarok (134 SpA) Flamethrower vs. 252 HP / 252 SpD Venusaur-Mega: 308-364 (84.6 - 100%) -- 6.3% chance to OHKO
So I guess you can OHKO a neutral nature Venusaur if you get the max damage roll on tera Fire Flamethrower. Though other Fire types with >134 SpA can do the same, of which there are quite a few. But with Choice Specs you don't even need the Tera and could also hit that with Ice Beam too.
252+ SpA Choice Specs Ramnarok (134 SpA) Ice Beam vs. 252 HP / 252 SpD Venusaur-Mega: 344-408 (94.5 - 112%) -- 68.8% chance to OHKO
And the other neat thing you can do with faster mons is run King's Rock and Serene Grace for 20% flinches on top of introducing more hax... I might be trying too hard to find something to talk about here for a fast mon unfavoured by fate, but it looks cool at least.
Also speaking of speed, I don't know if I've ever noticed this, but Zeraora and Dragapult have very similar stat spreads with single-digit differences, which is a bit interesting when one appears in the monthly top 10 occasionally and the other is barely discussed at all. That natural dual Dragon and Ghost typing goes a long way for the latter to stand out, and maybe also being shown earlier in the teambuilder when sorting by both base alphabetical order and BST. (Also I think Dragapult is cooler than Zeraora, or at least proven to be more popular being the #1 Galar mon in that 2020 popularity contest.)
Getting back on track to the usage stats of June 2025, this past month will show the complete ramifications of a new world without Pecharunt, marking a full year since
Pecharunt's first #1 ranking back in June 2024. Which reminds me to say, happy Bidoof Day and/or halfway mark of the year, depending on when I finish this post, eh. It's coming pretty close to midnight as of writing, but either way this also marks
5 years of posting about usage stats, 35 pages/~876 posts later.
In a way, everything has changed yet nothing has changed since then, but all remains dynamic and ever-changing by the day. I could say some selfish or sentimental stuff about this whole series and style of regular long-form posting, the small slice of the old forum culture's Internet it still stays on for now, and the serendipitous but somewhat relatively stable place it's inscribed into my life; but instead, I'll give a shared thanks to all the contributors and players and readers of this format and thread over time, even those just playing a single battle for fun that may never return or see this post, because there wouldn't be something to read or write about otherwise. It's always nice to see thoughts going around, as well.
So with that, back to getting back on track.

The battle count dips again to
23752, lower than the start of the year, but actually more than the same month last year.
June 2025: 1630-weighted top 10 + last month positions
#1: Mega Heracross (no change)

#2: Ting-Lu (#5)

#3: Mega Venusaur (no change)

#4: Mega Ampharos (no change)

#5: Blissey (#7)

#6: Mega Slowbro (no change)

#7: Dragapult (#9)

#8: Dusclops (#10)

#9: Iron Hands (#17)

#10: Necturna (#12)
Notably, Pecharunt is gone, and Ting-Lu has indeed reclaimed its former claim to fame as The bulky mon among mons, absorbing Pecharunt's leftover raw uses for major gains (2911 to 4586, moveset file stats) when most other mons have dropped with less games.
Regarding its variety of potential sets, it seems that Ice Scales has pushed a further lead over Unaware, almost gaining the majority of weighted usage at 47.5%. Minspeed Relaxed seems to still be going strong, and a main difference from last month is that tera Stellar has barely overtaken Ghost for prime tera type usage 44% to 41% (only under weighted usage, not raw where Ghost wins 42% to 34%, but still closer than last month's raw stats when Ghost had 46%, Grass was 18%, and Stellar was 16%), most likely due to the
sunlightbear post above aiming to simulate Pecharunt, but it's still interesting to see the practical change in action.
Also despite having 6% Flower Veil usage, there is still 10% tera Grass usage, which goes to show the usage of Flower Veil on a different mon supporting a potentially fat Ting-Lu, I guess. Goes to show the flexibility and selflessness of Flower Veil and its power of role compression in one effect across the whole team that you can still further stack another ability onto. I still find it so neat how this usually forgettable ability just feels like it fits perfectly for a particular niche in this environment, while still having an unignorable requirement. Man I love Flower Veil.
Not much else has changed within the top 10, but since last time, Blissey has risen in place and usage as well, and Abomasnow has also fallen, and Iron Hands and Necturna have stepped back up into the limelight. The former is a notable dark horse here with 635 raw uses, mainly with both Mega Heracross and Silvally-Ghost as partners.
Indeed, the other immediately noticed dark horse of Silvally-Ghost made it to #14 (277 raw uses from the moveset file), right under Mega Gengar's 2000~ uses, even with just only being publicly mentioned again a week ago. The linked Fat Scales team seems to be the most popular version, though it has a fair bit of alternate Ting-Lu teammate use as well. Also from the same post, Gourgeist-Super shows up at #25 with an even lower 134 raw uses, with 2/3rds represented by the Dauntless Shield/Weakness Policy set and the remaining being Ice Scales/Mirror Herb, with both still being Relaxed and partnered with Ting-Lu, though I notice there's conversely more usage for Tera Ghost than Stellar.
I would also like to shout out Glastrier making #11 with quite a bit of raw uses (2685), because it's been doing pretty well for itself just outside the top 10 as well, and that puts it at #6 in terms of just raw usage, above even the popular ghosts like Gengar, Dragapult, Sableye, and Hisuian Zoroark. Though it seems like it's commonly being run as a Ghost itself, and an Unaware one at that, though the Defiant and Simple usage combined rival it.
Moving into the moveset file and looking towards the viability ceilings (max GXE of a user of a mon), once again the leader of the month is not who you would probably expect like last month's Blissey or the new riser Ting-Lu or old Heracross, but is instead Mega Slowbro alone at
86, significantly ahead of all others. Ability usage seems to be mainly split between Competitive/Ice Scales/Unaware, though Weakness Policy has a major lead over Mirror Herb. Tera Ghost (39%) leads over Stellar (27%).
For some reason, the spreads show Quiet with 240 Speed EVs as the highest usage just over minspeed Relaxed, and I have no idea what that (140 raw Speed stat) would hit over minspeed or 252 Speed (143 speed). Maybe because the viability ceiling is only for one mon, this is some double Slowbro team and they want one to act first consistently, or at least have one minspeed for Perish Song while having a faster one to still take advantage of speed drops, while still underspeeding 252 Speed Slowbro? I really don't know, but all I can say is that last month, 252 Quiet was in the majority lead and this month it's nowhere to be seen. Maybe it is just to stand out.
Going forward and skipping a few steps, the next highest viability ceiling is 83 tied between Ting-Lu and Mega Camerupt (mainly Storm Drain, but split between Clear Amulet/Weakness Policy and Quiet 252 Speed/Brave minspeed). Tera Ghost leads as well (35%), but Ground and Fire are surprisingly split at 24%/22% and both above Stellar.
Skipping another step takes us down to 81 with Imposter Blissey, and Imposter set usage has gone up, along with Blissey teammates, tera Ghost usage, and also Relaxed minspeed is in the lead compared to last month's Sassy minspeed, though the combination of Quirky and Hardy would be greater than it. Now I suppose Relaxed is all right for Blissey vs. Blissey showdowns, but I don't know what brings someone to pick one neutral nature over another. Personally the nature I associate neutral natures with is Serious, probably because it was chosen for the Serious Mint.
Viability ceiling 80 has a 5-way tie between Heracross (typical Attack stuff, but notable 12% Defiant and 7% Mind's Eye and Pixilate usage...), Venusaur (still majority Flower Veil, but Good as Gold is over Magic Bounce and WP still over Herb, and mainly Heracross partners), Necturna (still typically sample Thick Fat with Brave minspeed, also Venusaur's 2nd main partner), Pokestar UFO (Delta Stream/Mirror Herb), and Enamorus-Therian (Delta Stream, but Choice Band leading over Mirror Herb).
Lastly, we can round out to a nice list of 10 mons, just one point down at 79 with Mega Ampharos alone (Plus/Minus both with more of a lead over Hadron Engine, Competitive, and Galvanize, but also Mega Heracross barely being more of a partner than fellow Ampharos). Thanks for your reading.
EDIT: I forgot to talk about Dragapult again, and there has been some new weird stuff going on with it that I've admittedly overlooked. It's been running mainly Fluffy/Mirror Herb for the past three months/since April (though Fluffy usage has been going down from 54% to 37%) instead of its typical potpourri of viable abilities and items, and seems to be with a Ting-Lu partner and Dragon tera (assuming it's not the designated tera user of the party). Also, it's been leading with a Naive (+Speed/-SpDef) nature, and I assume it's been the same person consistently for that reason. So I guess my tangent about speed could actually come full circle here.
