Hello! Having laddered with it for about a month now after playing nat dex for a year, I would like to nominate
NIHILEGO to B/B- (yes I made a smogon account just for this)
I used this mon on several teams over 3 accounts, and eventually I peaked at 1751, or number 65 on the ladder, with a team that eventually looked like this after several variations:
https://pokepast.es/4ee098774d484049 , originally a pretty basic HO that has become a near-mess of cheesy bo1 lure strats that open up Nihilego as much as possible (I know stone edge gyarados looks super dogshit but its to 1v1 kanto zapdos without static procing for my own zap it works promise). However, this team is slightly overkill, and I have found success (1600-1700) with less eccentric teams that contain more standard strategies and sets with Nihilego, such as this one:
https://pokepast.es/e4e84d50c4f7328d (tbh any Nihilego set -black sludge, meteor beam, spa beast boost- works here too, I just wanted to try make it more heat/bad).
I believe Nihilego has very good synergy with and a great matchup against the current metagame, especially on Hyper Offense, where it’s defensive capabilities greatly assist the playstyle’s attempts to find setup opportunity.
Metagame
I therefore believe that it should be ranked in B or B- using
Mega Gyarados, another HO staple who is in the B tier, as the benchmark. Gyarados’ well placed bulk and nice typing allows it to perform as a bulky setup sweeper in the face of common threats such as
Ash Greninja and
Weavile. Nihilego fills a similar role, utilising it’s massive 109/131 special bulk and unique typing to take advantage of the popular
Zapdos,
Clefable, non specs
Tapu Koko,
Zard Y running air slash instead of scorching sands,
Gengar, and any variant of
Volcarona that isnt hp ground modest. It also has the benefit of matching extremely well against the Zard Y + synthesis defog Kart team which the ladder loves so much right now, as well as sun in general, able to sweep easily once Kartana has been chipped or knocked out, as Kart cannot switch directly into meteor beam and stop Nihilego from outspeeding it after getting a ko.
+1 172 SpA Nihilego
Hidden Power Ice vs. 44 HP / 128 SpD Kartana: 165-195
(61.1 - 72.2%) -- guaranteed 2HKO
or maybe even just
+1 172 SpA Nihilego
Hidden Power Fire vs. 44 HP / 128 SpD Kartana: 660-780
(244.4 - 288.8%) -- guaranteed OHKO
Nihilego suffers against fatter teams, but I have found it able to acquire a second or third meteor beam boost in the face of pokemon like corviknight or bolt beam mega latias, or toxapex on the switchin in order to break holes in these teams if they lack a chansey.
Hp Ice
Nihilego's stabs are walled by both ground and steel types, and must therefore choose a hidden power type to beat one or the other. The set that I have found that works the best is power herb speed boost with hp ice, (with the other moves being meteor beam, sludge wave, and either power gem or a second coverage move) which takes advantage of the fact that the 3 most common ground types (
), who can stomach a +1 power gem and Ko back with earthquake, are all 4x weak to ice and can be taken out in one hit with hp ice after using meteor beam.
Garchomp in particular resists meteor beam and can therefore be sent out directly into Nihilego without needing to revenge kill it, so is even easier to take advantage of with hp ice. Also worth mentioning here is Nihilego’s great speed tier that puts it barely above Garchomp for this to be possible, while also allowing it to outspeed the majority of the metagame (31/37), including all 5 base 100s.

(115.1 - 136.1%) -- guaranteed OHKO
Synergy
HP Ice Nihilego has several flaws and many counters/checks, but they are worth building for because of how powerful it can be in the endgame. A spikes suicide lead on HO (
,
) can chip down the steel types such as
Melmetal,
Ferrothorn, and
Magnezone. One teammate in particular,
Tapu Lele, is capable of luring several of Nihilegos checks such as the aforementioned steel types as well as others such as
Mega Scizor,
Excadrill,
Heatran,
Tyranitar, and
Mega Mawile with any variant that is not choice locked, such as twisted spoon, assault vest, z fight, z psychic, and terrain extender, along with hp fire to fake being scarf to eliminate or damage them enough to cripple their ability to check Nihilego quickly.
Lele’s psychic terrain is also vital for Nihilego to prevent
Urshifu’s aqua jet,
Mega Scizor’s bullet punch, and
Mawile’s sucker punch from stopping its sweep, as well as
Greninjas water shuriken, but it is less important as it will only kill in rain while transformed.
Magnezone is another appreciated teammate on more balanced teams for its ability to trap Ferrothorn, choice locked Kart, and Mega Scizor lacking sand tomb, as is
Ferrothorn and
both Greninjas (while Nihilego checks Clefable for them) for the same reasons that Nihilego appreciates spikes on Hyper Offense.
Hp Fire
Alternatively, you can run hp fire and completely reverse Nihilego's checks.
AV Melmetal,
Chansey,
spdef Heatran,
Toxapex, and
Slowking-G remain as sturdy switchins to this set and still need extremely high hazard support to break through, but
Mega Scizor,
Ferrothorn outside of rain,
Magnezone and
Mega Mawile after some chip, and
Excadrill are now nearly setup fodder for Nihilego as all can be KOd after either taking meteor beam themselves or being chipped, at the expense of being unable to reliably stop
Landorus,
Gliscor, and
Garchomp from revenge killing it. Lando and Chomp can be taken advantage of through abusing their lack of recovery with more hazards and chip damage over a longer game, meaning the hp fire set is more appropriate on balanced teams.
Spdef Gliscor is a difficult roadblock for this set consistently, however, and must be lured with the now declining steel beam
Heatran or a similar surprise zmove/hp ice lure like Lando.

(71.4 - 84.2%) -- guaranteed 2HKO
More Synergy
Another great synergy I have found specifically is with the recently flourishing protean
Greninja, a great spikes suicide lead itself, and who, similarly to Lele, fakes being another set (ash) to lure
Mega scizor leads and
Ferrothorn with hp fire, which is especially beneficial to hp ice Nihilego; it is also able to get the required damage on
Melmetal and
Chansey with low kick (along with taunt to prevent healing) that either Nihilego set can win. With its focus sash intact, it can even sometimes take out
Kartana. In return, Nihilego wins the game lmao
Bulk
Because Nihilego must drop some spa evs in order to receive a speed boost from beast boost, the remaining 76 evs (or more) can be invested into bulk to live attacks that it would not be expected to:
0 Atk Technician
Scizor-Mega Bullet Punch vs. 0 HP /
56 Def Nihilego: 302-356
(84.1 - 99.1%) -- guaranteed 2HKO (You aren’t doing much back here on the hp ice set, but it has been relevant in the final few turns of a game where it comes down to this 1v1, and the hp fire set appreciates surviving this to beat Mega Scizor more consistently)
252+ Atk
Hawlucha Close Combat vs. 0 HP /
84 Def Nihilego: 265-313
(73.8 - 87.1%) -- guaranteed 2HKO
after Stealth Rock (nihilego always kos back after the spdef drop at +1)
252 Atk
Choice Band Urshifu-Rapid-Strike Aqua Jet vs. 0 HP /
96 Def Nihilego: 302-356
(84.1 - 99.1%) -- guaranteed 2HKO (or scarf Urshifu in rain)
252 SpA
Heatran Earth Power vs. 0 HP /
44 SpD Nihilego: 300-356
(83.5 - 99.1%) -- guaranteed 2HKO (timid only)
200 SpA
Kyurem Earth Power vs.
0 HP / 0 SpD Nihilego: 300-356
(83.5 - 99.1%) -- guaranteed 2HKO (no bulk required against subroost)
Because of the high pressure of HO it is not as difficult as it seems to keep Nihilego at full hp and preserve its ability to live these hits by preventing hazards from going up.
Most of these calcs, however, display physical attacks against Nihilego, and all of them are hardly safe switchins, but there are many safer attacks and Pokemon that Nihilego can switch into in the current meta using its natural special bulk (no investment required) that it can benefit from on both offense and HO:
0 SpA
Clefable Moonblast vs. 0 HP / 4 SpD Nihilego: 39-46
(10.8 - 12.8%) -- possible 8HKO
252 SpA
Tapu Lele Moonblast vs. 0 HP / 4 SpD Nihilego: 61-72
(16.9 - 20%) -- possible 5HKO (when already locked into moonblast via scarf)
0 SpA
Zapdos Discharge vs. 0 HP / 4 SpD Nihilego: 84-99
(23.3 - 27.5%) -- 69.3% chance to 4HKO
252 SpA
Charizard-Mega-Y Weather Ball (100 BP Fire) vs. 0 HP / 4 SpD Nihilego in Sun: 113-133
(31.4 - 37%) -- 80.8% chance to 3HKO
0 SpA
Torkoal Lava Plume vs. 0 HP / 4 SpD Nihilego in Sun: 45-54
(12.5 - 15%) -- possible 7HKO
252 SpA
Gengar Shadow Ball vs. 0 HP / 4 SpD Nihilego: 103-123
(28.6 - 34.2%) -- 2.3% chance to 3HKO
252 SpA
Tapu Koko Thunderbolt vs. 0 HP / 4 SpD Nihilego in Electric Terrain: 121-144
(33.7 - 40.1%) -- guaranteed 3HKO
+1 252 SpA
Volcarona Psychic vs. 0 HP / 4 SpD Nihilego: 238-282
(66.2 - 78.5%) -- guaranteed 2HKO
Flexibility
Finally, another reason I believe Nihilego may be deserving of an higher position than the rest of the C/B- tier is because of its greater flexibility to be used on balance and especially offense than many of the other members of the tier, such as the previously mentioned
Mega Gyarados who is exclusive to HO, or
Shuckle on webs HO,
Shedinja on stall,
all the weather mons, and whatever
Mega Heracross does (trick room…?). An assault vest or black sludge set makes the most of Nihilego’s special bulk to check several special attackers in the tier, and it provides utility through setting rocks and tspikes and absorbing opposing tspikes for the team, as well as being able to use knock off. The black sludge set can also run pain split which allows it to recover massive hp from
Chansey and other walls who are common switchins, providing longevity on balance; meanwhile, the AV set works better on offence where teams are not designed for overall longevity anyway. The final set I want to mention is the choice scarf set, which can revenge kill much of the tier (including scarfers such as
,
,
,
,
, even the occasional
and
)and can fit more coverage than a meteor beam set, with options such as dazzling gleam, grass knot, and thunderbolt being easier to slot on, as well as being able to snowball with special attack beast boosts in a similar way to scarf kartana. These sets work with
Magnezone and
Lele again on these more balanced teams, as well as
Heatran and
Fini who are capable of trapping and heavily damaging/taking out
Chansey and spdef
Toxapex for it, while in return it checks
Zapdos for them so that Heatran does not have to take unnecessary damage or get paralysed, making every magma storm a coin flip. I did not explore these utilities of Nihilego as much as the meteor beam sweeper role but I have still used them and believe they have a niche.
Conclusion
In conclusion, what holds back Nihilego from being more than a HO move clicker or niche special wall the most is being walled eternally by one of either steel or ground depending on its hidden power choice, as well as most dedicated special walls (
Chansey,
Pex,
Slowking G, maybe even
Tyranitar) and it is always left needing another coverage option for those neutral to the hidden power, e.g. grass knot for
Swampert, thunderbolt for spdef
Toxapex, I’ve even experimented with acid spray to 1v1
Chansey (it worked about once). However, current metagame trends greatly favour Nihilego and its special bulk and typing, as well as its synergy with common meta threats who remove its checks for it, to such an extent that I think it should rise for how well it fills its niche(s).
In short (tl;dr ig), the metagame trends that favour Nihilego are:
Zapdos rising = good for Nihilego because it walls Zap
Ash gren falling = less competition for Nihilego in the cleaner/wallbreaker role
Lele rising = Nihilego's best teammate is becoming more popular
+
this team style rising = good matchup for Nihilego
Protean gren rising = good for Nihilego because it likes spikes + surprise hp fires/low kicks
Rillaboom, Nihilego's best revenge killer, falling = psychic terrain can be kept up more often and Nihilego is less likely to be stopped
Both moltres’ rising = setup fodder for Nihilego, and walls both if kanto moltres isnt scorching sands
REPLAYS
These are all involving the team I peaked with, using the hidden power ice meteor beam sweeper set on this not-quite-hyper offense, as this is the primary niche I believe Nihilego fills and what it does its best at.

Here a few things are displayed. Firstly, Lele’s ability to lure and take out the Excadrill who would have been a blockade to Nihilegos sweep, although it was scarf which is an unset anyway but he didn’t iron head so we move
Secondly Nihilego shows how it can make use of its insane special bulk, able to setup easily on Moltres despite a flinch.
Thirdly is Nihilego’s cleaning capabilities and powerful speed control in the form of beast boost, knocking out half the opponents team and outpacing Hawlucha in the end. This is also the highest replay I have so kinda proof of peak (I hadn’t started saving replays for this until after the original peak).
https://replay.pokemonshowdown.com/gen8nationaldex-1606704549-s14jqv7d44cy3mz0ewb4g1hqqtjirrmpw
Mega Gyarados lures Swampert, the only Nihilego check, with power whip and Nihilego is free to break a massive hole in the opponents team (maybe lucky finding the only Latias on ladder without psyshock).
https://replay.pokemonshowdown.com/gen8nationaldex-1603942130-7xvhpzudyprt5sy288m1lfa32m0wl5kpw
Lele lures Ferrothorn, Mega Gyarados tries to lure Swampert but eventually takes it out with Melmetal, Nihilego now has no switchins and cleans up with Zapdos G after surviving a kanto Zapdos weather ball
https://replay.pokemonshowdown.com/gen8nationaldex-1600400363-cpf1mewi297ddnoa7wdizcmkjznq9ekpw
Umbreon and Corv, the only 2 Pokémon able to take a hit from +1 Nihilego (although umbreon probably loses the 1v1) are heavily damaged by Gyarados, and Nihilego is able to win on the spot despite the hax
https://replay.pokemonshowdown.com/gen8nationaldex-1600345712-x20lm84itn673tjtl7kghzsdgjyz8b7pw
Here the calc that allows Nihilego to survive a Hawlucha close combat comes into play, and although the opponent forfeited prematurely, it would still have at least knocked out Hawlucha and heavily damaged gyarados before being KOd.
https://replay.pokemonshowdown.com/gen8nationaldex-1600336236-i74oerfu8oq6pqe5228g897v1pg3owzpw
Nihilego is able to take advantage of the element of surprise with hp ice to take out Lando and gain the speed boost necessary to outspeed Eleki and win
