Answer 1

Necrozma National Dex AG
--->
Necrozma-Dusk-Mane @ Ultranecrozium Z / Life Orb
Ability: Prism Armor
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Photon Geyser / Psychic Fangs
- Sunsteel Strike / Stone Edge
- Morning Sun / Stealth Rock / Dragon Dance
- Earthquake

- Photon Geyser strong STAB that uses Necrozma's attack stat because it's higher, and when Ultranecrozium Z is activated the move turns into "LIGHT THAT BURNS THE SKY" and does damage based on the users attack or special attack just like Photon Geyser while also transforming you into Ultra Necrozma, and it also ignores the target's ability.
- Psychic Fangs another STAB option if you plan on dynamaxing DM Necrozma then Psychic Fangs can be used in place of Photon Geyser while also running life orb instead.
- Sunsteel Strike strong STAB and just like "Light that burns the sky" Sunsteel Strike ignores the target's ability.
- Morning Sun reliable recovery move to increase DM Necrozma's longevity tho this move takes up a turn that could be used for attacking.
- Earthquake good coverage for fire and steel types.
- Stealth Rock used to weaken the opposing team softening them up and making it easier to sweep.
- Dragon Dance to power up Necrozma's already great attack and speed and allows it to sweep entire teams especially when dyanmaxed, the same goes for Ultra Necrozma (not dynamaxed).
- Stone Edge works as good coverage against flying types.

Necrozma DM pairs very well with Primal Groudon, it can be a secondary stealth rocker so groudon can use more offensive moves, it also works as a great Xerneas check. Primal Groudon can handle other steel and fire types for Necrozma DM to take pressure off of it and allow it to take on other tasks like putting up rocks.
Other good teammates include Zygarde, Eternatus, Mega Gengar, and Mega Rayquaza.

Comments

Ultra Necrozma should have Stone Edge over Sunsteel Strike for hitting Yveltal and Ho-Oh (not Life Orb set). Also, Dragon Dance is a good alternative to SR/SD/Morning Sun because you get to outspeed Arceus formes on base NDM and Calyrex-S, Zacian-C as UNecro at +1. Also, Mega Salamence and Naganadel are bad because they're heavily outclassed by Mega-Rayquaza and Eternatus.

sorry for not specifying enough on this but the life orb set is not used on ultra necrozma but on DM necrozma if you want to dynamax it, but thanks for all the advice :).

I meant that, you're fine with having Sunsteel Strike on LO NDM, but Ultra Necrozma needs Stone Edge.

Ok made some edits.

Answer 2

Gen 9 NU Dragon Dance

Necrozma @ Lum Berry / Weakness Policy
Ability: Prism Armor
Tera Type: Ground
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Dragon Dance
- Photon Geyser
- Earthquake
- Knock Off / X-Scissor

A Dragon Dance set for Necrozma if you want to use Dragon Dance in Gen 9 NU. Dragon Dance boosts Necrozma's Attack and Speed stat to make it a scary sweeper. Should you get off 2 Dragon Dances, Necrozma can outspeed most of the faster Pokemon. Photon Geyser is used for the Psychic STAB since this is a physical set, making it stronger than the other physical Psychic STABs Necrozma has. Photon Geyser also ignores abilities, allowing you to bypass Quagsire's Unaware. Earthquake allows Necrozma to send Steel-types such as Registeel, Copperajah, Klefki, and Magnezone, as well as Pokemon such as Alolan Muk, Armarouge, Incineroar, Overqwil, and Galarian Slowbro down to the Earth's core. Knock Off allows Necrozma to remove items from opposing Pokemon and also lets Necrozma hit opposing Psychic-types such as opposing Necrozma, Slowbro (the Kanto one), Reuniclus, and Mew. Alternatively, you can use X-Scissor so you can also hit Dark-types such as Krookodile, Umbreon, and Brute Bonnet super effectively. Plus, Psychic/Ground/Bug coverage is weirdly good offensively. Lum Berry allows Necrozma to heal itself from a status condition that would hinder its ability to sweep. Weakness Policy can be used to get a +2 Attack boost when its hit by a super effective move. Tera Ground is used to make Earthquake a STAB move and block Thunder Wave from a Pokemon such as Klefki.

Answer 3

Gen 9 NU Bulky Calm Mind

Necrozma @ Grassy Seed
Ability: Prism Armor
Tera Type: Poison
EVs: 252 HP / 4 Def / 252 Spe
Timid Nature
IVs: 0 Atk
- Calm Mind
- Stored Power
- Earth Power
- Moonlight

A Bulky Calm Mind set Necrozma can use in Gen 9 NU. This set must be used on Grassy Terrain in order to work. Get in Necrozma safely while Grassy Terrain is up so Necrozma can consume its Grassy Seed to get a Defense boost to make it harder for physical wallbreakers to wear it down. Grassy Terrain gives Necrozma a little HP recoveryCalm Mind allows Necrozma to boost its Special Attack and Special Defense stats to make it harder for Special wallbreakers to wear it down while boosting its offensive presence. Stored Power is used for the Psychic STAB since it gets really powerful from the defense boost from Grassy Seed and the Special Attack and Special Defense boosts from Calm Mind. Earth Power is used for coverage against Pokemon such as Registeel, Copperajah, Magnezone, Armarouge, Alolan Muk, Incineroar, and Overqwil. Moonlight is used to give Necrozma some HP recovery so it can stay out of range of attacks KOing it. Tera Posion is used so Necrozma can be immune to Toxic while still resisting Fighting moves. Tera Posion can also let Necrozma setup in front of Alolan Muk. Grassy Terrain also halves Earthquake damage when it is up, which helps Necrozma when it teras.
