Overview

Alongside the likes of Flareon, Limber Stunfisk, and Final Gambit Shedinja, Rotom-S is often described as one of Game Freak's attempts to troll competitive battlers. Thanks to its newfound Electric / Flying typing, Rotom-S is the only Pokemon in the game with a double immunity to Ground-type moves (and a triple immunity, if given an Air Balloon!). Rotom-S is generally considered the least useful Rotom forme because of its STAB move, Air Slash's, mediocre Base Power, its Stealth Rock weakness, and its unremarkable STAB coverage. Despite this, Rotom-S is an outstanding performer in NU with the capability to pull off a myriad of sets. Rotom-S also has an excellent base Speed for a Choice Scarf user, allowing it to outspeed common threats such as Shell Smash Gorebyss and Choice Scarf Sawk. Whether you're looking for a reliable revenge killer, a sturdy status platform, or if you're just in dire need of a double Earthquake immunity, look no further than Rotom-S.

Choice

Choice Scarf / Choice Specs Timid
Moveset EVs
~ Volt Switch
~ Air Slash
~ Thunderbolt
~ Trick / Hidden Power Grass
4 Def / 252 SpA / 252 Spe

Rotom-S has the quintessential stat build for a Choice item user, coupling a solid Special Attack stat with a usable Speed stat. When equipped with a Choice Scarf, Rotom-S's niche base 86 Speed allows it to just barely outpace Choice Scarf Sawk and +2 Shell Smash Gorebyss, as well as other common Pokemon below that Speed, such as Swellow. Choice Specs, on the other hand, gives Rotom-S a much better chance to achieve key KOs.

Volt Switch allows Rotom-S to net momentum, scare out opposing Water- and Flying-types, and scout out the opponent's team. However, Thunderbolt nabs several OHKOs that Volt Switch misses out on, such as on an opposing Braviary with a little prior damage, and is Rotom-S's most powerful and reliable STAB move. Air Slash gives Rotom-S its Flying-type STAB, and lets it KO vital Pokemon such as Leafeon, Torterra, and Sawk. The last moveslot is simply a matter of preference. Trick is generally the more beneficial move, granting Rotom-S the opportunity to switch moves, as well as letting it incapacitate common switch-ins to Rotom-S, such as Lickilicky, Golem, and Camerupt. However, Hidden Power Grass allows Rotom-S to hit both Seismitoad and Rock / Ground Pokemon, such as Golem, who resist both of Rotom-S's STABs.

Rain Dance

Damp Rock Levitate Modest / Timid
Moveset EVs
~ Rain Dance
~ Thunder
~ Air Slash
~ Volt Switch / Hidden Power Grass
4 Def / 252 SpA / 252 Spe

With its excellent offensive and defensive typing, Rotom-S makes an excellent user of Rain Dance. By virtue of its easily spammed STABs, Air Slash and Thunder, it checks many Pokemon that cause great trouble to rain teams. Thunder is perfectly accurate in rain, boasting 180 Base Power after STAB and amazing coverage. It fries every bulky Water-type not named Seismitoad, which is extremely helpful for the numerous rain sweepers that cannot hope to break past them. Additionally, it possesses a 30% paralysis chance that benefits slower Pokemon who might attempt to make use of the rain, such as Octillery. Air Slash is Rotom-S's other STAB move, having excellent coverage with Thunder and hitting the many Grass-types populating NU super effectively; this is important because of the resistance these Pokemon have to Water-type attacks. In a pinch, Rotom-S can attempt to use the combination of Air Slash's flinch and Thunder's paralysis to break through any troublesome opposition, though Rotom-S should have teammates that can prevent this need from arising in the first place.

While Rotom-S's Flying typing benefits him offensively with a STAB Air Slash, it is also a huge plus defensively. It enables Rotom-S to take Grass-type attacks directed towards the rain sweepers it is often partnered with. In this way, Rotom-S is one of the best teammates a rain sweeper might desire. The last moveslot is mainly based on personal preference; Volt Switch allows Rotom-S to bring in a teammate for free and obtain momentum, but Hidden Power Grass also has use to smack Seismitoad and Golem, both of which are common switch-ins to Rotom-S.

Defensive

Leftovers Bold
Moveset EVs
~ Will-O-Wisp
~ Discharge
~ Pain Split
~ Air Slash
252 HP / 252 Def / 4 SpD

Rotom-S has a solid defensive typing coupled with excellent natural bulk, making it a great defensive pivot and status platform. Will-O-Wisp is the cornerstone of this set, as it cuts the Attack of opposing Pokemon and allows Rotom-S to take physical hits much more easily. Discharge offers STAB as well as a strong chance of paralysis, which is helpful when dealing with Pokemon who aren't bothered by Will-O-Wisp, such as Rapidash. Pain Split, although not the most reliable form of recovery, takes advantage of Rotom-S's naturally low base 50 HP and is the best that Rotom-S can muster. Lastly, Air Slash provides secondary STAB and coverage on the ever-present Grass- and Fighting-types that occupy the tier. It also provides a useful flinch chance, giving Rotom-S the Jirachi-esque ability to paralyze opponents with Discharge and render them helpless by flinching them to death with Air Slash.

Substitute

Life Orb / Leftovers Timid
Moveset EVs
~ Substitute
~ Thunderbolt
~ Air Slash
~ Pain Split / Charge Beam
4 Def / 252 SpA / 252 Spe

Substitute works well on Rotom-S thanks to its great defenses, solid typing, and ability to force switches. The idea of the set is very simple: come in on a Pokemon that Rotom-S scares out, such as Alomomola, and set up a Substitute. From there, Rotom-S can wreak havoc with Thunderbolt and Air Slash, which provide decent coverage together. However, it is the final moveslot that establishes the purpose of this set. Pain Split allows Rotom-S to wear down opposing special walls, such as Lickilicky, and should be used with Life Orb. Charge Beam, on the other hand, gives Rotom-S the ability to boost its Special Attack when behind a Substitute, and should be used alongside Leftovers, as Rotom-S will have no other form of recovery.

~ Substitute / Pain Split
4 Def / 252 SpA / 252 Spe

Second only to Jirachi in annoyance rate, Rotom-S has access to one of the most frustrating movesets in the entire game. When the opponent is paralyzed, confused, and is being bombarded by Air Slash, they have just a 26% chance to actually attack Rotom-S. Air Slash is the primary offensive move of this set, as its impressive flinch rate allows Rotom-S to hammer through nearly any Pokemon untouched, once they are paralyzed and confused. Discharge is the Electric-type move of choice, as it presents a 30% chance of paralysis while also providing Rotom-S with an attacking move outside of Air Slash. Thunder Wave is an option, however, if you prefer to have guaranteed paralysis. Confuse Ray adds another status-inducing move to the mix, halving the chance of the opponent hitting Rotom-S. Substitute prevents status moves, such as Toxic, from wearing down Rotom-S, as well as allowing it to rack up Leftovers recovery much more easily. Pain Split, on the other hand, offers recovery, but Rotom-S becomes significantly more prone to status moves.

Other Options

Rotom-S has access to both Reflect and Light Screen, as well as Volt Switch, making a dual screens set a viable consideration. If the unreliability of Pain Split is bothersome, Rest and Sleep Talk are available, but Rotom-S almost never has the room to give up an extra moveslot. Shadow Ball seems like an interesting coverage option, hitting the common Psychic- and Ghost-types in the tier, such as Misdreavus and Haunter, for super effective damage, but the coverage it provides is usually inferior to Hidden Power. A Rain Dance support set with Thunder is also a curious option, making Rotom-S one of the more effective Rain Dance users.

Checks and Counters

Despite Rotom-S's double immunity to Ground-type moves, Ground-type Pokemon generally make for the best checks and counters. Golem isn't bothered by any of Rotom-S's attacks sans Hidden Power Grass, can set up Stealth Rock to discourage Rotom-S from coming back in, and can break its Substitutes with Rock Blast. Likewise, specially defensive Camerupt sets up Stealth Rock in its face, and Roars it away as it struggles to do anything in return. Lickilicky can handle any move Rotom-S can throw at it and heal back up with Wish, as well as remove any status Rotom-S has spread with Heal Bell. The simplest way to deal with Rotom-S is to maintain Stealth Rock, limiting the amount of times it can return to the battle.
