reserving mega slowbro


Slowbro @ Slowbronite
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Toxic
- Scald
- Slack Off
- Iron Defense

Due to its amazing defenses and typing and the ability not to get struck by a critical hit Mega-Slowbro serves as a very good check to this Dusk Mane set.
Mega-Slowbro can come in on any attack even when Dusk Mane is at +2 due to Swords Dance - Dusk Manes Sunsteel Strike won't do a lot
to Mega-Slowbro and Z-Sunsteel Strike won't OHKO Slowbro-Mega either. Mega-Slowbro is also tank enough to take a +2 Z-Sunsteel Strike into an Earthquake.
In return Mega-Slowbro can Slack Off the damage it took and has a chance to burn Dusk Mane with its Scald, also Mega-Bro can just iron Defense up to neutralize the +2 gained due to Swords Dance
by Necrozma-Dusk Mane.

on a more serious note:

Skarmory completely walls everything and anything Dusk Mane throws at it barring weird heat wave coverage while whittling it down with both Rocky Helmet recoil and Spikes chip, using Iron Defense to withstand even +6 hits in lastmon scenarios. It's simply no contest unless you're already coming in on an already set up dusk, which only a +4 one can OHKO you.

Ability: Shadow Shield
Shiny: Yes
EVs: 116 HP / 192 Def / 200 Spe
Timid Nature

Here comes the great wall that covers most of offensive Necrozma sets! Lunala's great ability, Shadow Shield can even nullify Sunsteel Strike and Searing Sunraze Smash's effect that nullify the opposing mon's ability, and it's good speed makes it outspeed Necrozma-DM easily, the given speed EVS and Timid nature are aimed to outspeed max speed pdon, pogre as well as Ho-oh, the rest are invested into HP and defence, enables it to survive a +2 boosted Searing Sunraze Smash from max attack Necrozma DM as well as roost to max HP after taking a max spA pdon's Eruption and leftovers damage.

Ho-Oh as a soft counter
​

Ho-Oh @ Leftovers
Ability: Regenerator
EVs: 144 HP / 212 Def / 152 Spe
Impish Nature
- Sacred Fire
- Recover
- Toxic
- Defog

Defensive Ho-Oh has a great matchup against Necrozma-DM just by its typing alone, letting it resist Sunsteel Strike and be immune to Earthquake. The EVs were optimized so that Ho-Oh can take one Searing Sunraze Smash after Stealth Rock or a +2 Searing Sunraze Smash from full HP and still outspeed it, letting it recover the damage and procced to deal huge damage with Sacred Fire and even burn it. It can also come into it multiple times due to Regenerator negating the damage of Sunsteel Strike if rocks are off the field.

hey foul play is a better choice that can punish other set up sweepers such as facade Salamence-mega, since scald may burn it at a predicted switch in , which makes u can't Toxic it then

I choose rotom-w )

Rotom-Wash @ Leftovers
Ability: Levitate

EVs: 252 HP / 248 Def / 8 SpD
Bold Nature
IVs: 0 Atk
- Reflect / Defog
- Will-O-Wisp / Toxic
- Foul Play
- Pain Split

Wash rotom is pretty good with this set honestly. If you need a defogger you can run it or choose something like toxic for support arceus switchin or reflect if you really worry about physical damages. Wisp + fp is all you need to counter ultrznecrozmium sets , 4x resist + eq immune helps check almost all the ground type sweepers in the tier. Also pain split is really broken in this tier with high hp targets so rotom can sustain with more than just leftover recovery.The combination of rotoms typing ability and set i have do not allow rotom to lose to even hax vs a double dance necrzoma.

Ironically reserving Scarf Yveltal
Actually reserving Mega Gengar

Gengar-Mega @ Gengarite
Ability: Cursed Body
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Hex
- Will-O-Wisp
- Sludge Wave
- Taunt

Mega Gengar is a solid check to Necrozma-Mufasa. I chose the Hex set for a specific reason here—Mega Gengar’s Shadow Ball can’t OHKO NDM while it EQs in return. However, Will-O-Wisp makes EQ do 75 maximum, and a 130 BP Hex kills guarenteed. Obviously, Gengar cannot switch in, but it separates itself from others with a unique trait; Necrozma can’t switch out. This can be amazing for every Steel-weak setup sweeper (ahem Life Deer) and it still manages to do well in MUs outside of this, so yeah. Check.

 

[PrAiSe GrOuDoNiSm]

Celesteela @ Leftovers
Ability: Beast Boost
Shiny: Yes
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
IVs: 0 Atk
- Leech Seed
- Substitute
- Protect
- Flamethrower

Celesteela can be one the most solid checks to DM being immune to Earthquake and resisting Sunsteel Strike. The strategy is simple. All one needs to do is to use leech seed in the first turn and then spam protect and substitute alternately. In the end DM dies a slow death with Celesteela having a considerable amount of hp left thanks to leftovers recovery and leech seed restoring Celesteela's health through the hp sapped from DM. Protect+Substitute combo frustrates DM as Substitute ensures DM can't keep on using swords dance freely and Protect saves a turn assisting the hp exchange. Flamethrower is a good option otherwise Celesteela gets completely walled by Ferrothorn and it helps a bit in this case too.

Darkinium Z Yveltal

Yveltal @ Darkinium Z
Ability: Dark Aura
EVs: 68 Def / 252 SpA / 188 Spe
Lax Nature
- Foul Play
- Dark Pulse
- Sucker Punch
- Oblivion Wing
​

Yveltal is one of Necrozma's best checks due to being a Bulky Attcker that makes him OHKO with Z move and 2HKO without Z move. Besides, he holds a Z move perfectly without Swords Dance of Necrozma and he holds a Sunsteel Strike after Swords Dance, besides of That when Throwing Swords Dance and Mataria So Yawning is not Necrozma option that makes it one of the best Checks

[Inspirited]

Check
If it wasn't obvious, then let it be known that a healthy Kyogre can check a vast majority of the common metagame at the moment.

The special attackers with speed do the best here due Primal Kyogre's solid OHKO on them with Origin Pulse, natural Speed advantage on Necrozma, and resistance to Searing Sunraze Smash. If Necrozma boosts Speed, then it fails to KO a healthy Kyogre with any of its common and necessary attacks. If Necrozma boosts its Attack, then the only hope it has is an Origin Pulse miss.

Defensive Kyogre doesn't do as well due to its lack of damage. The only thing it can threaten a healthy Dusk Mane with is a Scald burn, which is enough in some cases due to just how bad a burn is for Dusk Mane. Because of this lack of damage, the Necrozma player can decide to boost in front of Kyogre and hope for a 3/8 roll to KO with SSS after Stealth Rock damage or its equivalent 1/8. The physical attacking Kyogre needs lots of damage in order to check an already boosted Dusk Mane.

Necrozma has ways of getting around Kyogre with its ability to Ultra Burst and use Trick Room with HP investment, so Kyogre should never be the sole answer. Kyogre teams tend to have ways of dealing with a damaged Ultra Necrozma whether it be Marshadow or a Choice Scarf Xerneas. The Trick Room interaction gets a little problematic because the CS Xerneas follow-up doesn't work all of a sudden and the Marshadow will leave your game in a rather nasty situation likely staring down a Groudon or their own Kyogre under Trick Room. There are ways to play around with with your own slower mons and that usually involves taking nasty damage with your own Groudon, but it is something to have in mind if you're going to force damage on Necrozma with Kyogre.

this is a dangerous mind game, ur opponent may click swords dance to predict a roost, even u click curse, it's Z-move can still deal the same damage, not to mention u should always keep it at full HP, thus it's not so solid as it looks, the only physical wall can counter it is mega slowbro carries Iron Defence imo, Skarmony is also a choice, but it always lacks a slot to carry Iron Defence, then it always faces the mind game that similar to mega Scizor: roost or whirlwind

ppl should pray a crit to kill it, or it just clicks rest and revives

- Overheat

Defensive PDon can come in once on any of Dusk Mane's moves and as long as it's at nearly-full HP will live any two hits - or any one +2 hit - without fail. Overheat OHKOs Dusk Mane in return. Accuracy can obviously prove problematic as a single miss will probably get you 6-0'd but PDon is about as bog-standard of a Dusk Mane check as you can get, especially since it's on 99% of teams. Its presence alone is generally enough to force Dusk Mane out and as a result you can start getting spicy with your predictions; you can get Rocks up or Toxic something, or you can just go for one of your STABs since they still blow a gaping hole in anything trying to switch in on you anyway.

If you're looking for an actual counter to this fucking thing without relying on something extremely unorthodox that exists solely to counter this set then good luck though.
