[OVERVIEW]
Necrozma is a decent Trick Room setter and setup sweeper in Doubles OU due to its unique ability and movepool. Prism Armor, Necrozma's signature ability, prevents some Ghost- and Dark-type attackers from OHKOing it. This gives it a distinct niche, since strong Ghost- and Dark-types are often used as a team's primary answer to Trick Room setters. Furthermore, Necrozma is capable of becoming a major offensive threat after a couple Calm Mind boosts. However, Necrozma suffers from four-moveslot syndrome, wanting to run a STAB move, a coverage move, Trick Room, and various other status moves all at the same time. Perhaps its greatest flaw is that it struggles versus Steel-types and is completely walled by Dark-types, since it typically only runs Stored Power as its attacking move. This makes it a liability in many matchups. On top of all this, it faces intense competition from other Trick Room setters, lacking the offensive presence of setters such as Hoopa-U or the utility of setters such as Bronzong.
Due to all of its flaws, Necrozma should really only be used on full or semi-Trick Room teams that need a reliable check to special attackers. In the vast majority of cases, Necrozma's role as a Trick Room setter can be better fulfilled by either Bronzong or Hoopa-U.

Moves
========
Stored Power is Necrozma's sole attacking move, allowing it to hit harder with every stat boost from Calm Mind. Calm Mind lets Necrozma hit harder and set up freely versus opposing special attackers. Moonlight gives Necrozma extended longevity, which is especially useful after it has acquired some Special Defense boosts. Trick Room lets Necrozma and its team go first against faster foes.
Set Details
========
Leftovers gives Necrozma a means of passive recovery, which is quite useful after it has acquired some Calm Mind boosts. An EV spread of 252 HP / 252 Def / 4 SpD with a Relaxed nature maximizes Defense, since Calm Mind lets it boost its other stats. 0 Speed IVs should be used so Necrozma is as fast as possible under Trick Room.
Usage Tips
========
Necrozma works well as a lead alongside a Fake Out user or redirector in order to get up Trick Room straight away. You should try to keep Necrozma healthy throughout the match so it can be used as a late-game wincon. The combination of Calm Mind and Moonlight allows it to clean up once opposing Dark- and Steel-types have been removed. Once Necrozma has set Trick Room, it is often best to switch it out for a strong Trick Room attacker so it can make the most of the limited Trick Room turns. Generally, avoid setting up if your opponent still has Dark- or Steel-types in the back, since they can freely switch in and then set up or threaten Necrozma out.
Team Options
========
Strong, slow attackers such as Araquanid and Eruption Heatran are great partners, since they appreciate Necrozma's Trick Room support. Necrozma needs allies that can KO Steel-types, so strong Fire- and Ground-types are appreciated. Mega Charizard Y is a particularly good partner because it allows Necrozma to heal additional HP while Drought is up. Dark-types make for good partners because they can switch in on opposing Dark- and Ghost-type attacks, while Necrozma can KO Fighting-types in return. Scrafty is a good option, since it can aid Necrozma in setting Trick Room with its Fake Out, while Hoopa-U can also set Trick Room and reliably checks Steel-types. Redirection support from the likes of Amoonguss is appreciated, since it allows Necrozma to set Trick Room without having to be worried about getting KOed or Taunted.

Other Options
=============
Psyshock can be run over Stored Power if you want more immediate offensive power, since Stored Power is rather weak without multiple prior stat boosts. For example, Psyshock allows Necrozma to 2HKO Mega Gengar and Terrakion straight away, while Stored Power does not. Hidden Power Ground can be run to hit Steel-types such as Heatran and Aegislash, and it also hits Tyranitar. Necrozma can utilize Iron Defense well, which boosts its Defense and the strength of Stored Power. Similarly, Grassy Seed can be used over Leftovers if you pair Necrozma with Tapu Bulu. Necrozma can use Safety Goggles to effectively check Amoonguss, which otherwise shuts down many Trick Room teams.
Checks and Counters
===================
**Dark-types**: Dark-type Pokemon such as Hoopa-U and Tyranitar are immensely threatening because they entirely wall Necrozma's typical set. They can then proceed to 2HKO it with their strong Dark-type attacks.
**Steel-types**: Steel-type Pokemon such as Heatran, Aegislash, and Celesteela can set up Substitutes versus Necrozma and easily take Calm Mind-boosted Stored Power. They can then proceed to whittle it down with Heat Wave, Shadow Ball, or Leech Seed, respectively.
**Taunt and Substitute**: Taunt users such as Mega Gengar and Tapu Koko completely shut down Necrozma, preventing it from setting Trick Room or using Calm Mind. At that point, it will most likely be forced to switch out. Substitute attackers such as Heatran and Aegislash are also super threatening because they can soak up Psychic-type attacks, set Substitute, and continue to fire off attacks behind the safety of a Substitute.
**Opposing Weather**: Rain, sand, and hail prevent Necrozma from healing as much HP with Moonlight, making it much harder to stay healthy. Tyranitar is particularly threatening because its Dark typing also lets it wall Necrozma.
