Rotom and its five other forms have varying degrees of viability based primarily off of typing and utility in specific metagames. Rotom-Wash is the most viable of the forms, residing in the OverUsed (OU) tier. Rotom-W is a phenomenal pivot Pokemon with Volt Switch and its typing gives it the ability to check many top-tier metagame threats such as Azumarill, Talonflame, and Landorus-T. Rotom-W’s access to Will-O-Wisp and decent bulk make it a great utility Pokemon that can offer momentum for a team due to Volt Switch. Rotom-W’s biggest flaw is its relatively low 50 base HP and having to rely on Pain Split for recovery when it can be relatively unreliable.
Rotom-Heat is currently placed in the UnderUsed (UU) tier. Its great typing grants it 8 resistances to go along with Levitate to negate its x4 weakness to Ground-type attacks. Rotom-H has good bulk, utility in moves like Will-O-Wisp and Volt Switch, and a great STAB combination that gives it solid coverage. Rotom-H can perform a defensive pivot role, a strong nuke with Choice Specs, or a speedy revenge killer with Choice Scarf. Unfortunately, Rotom-H has a low 50 base HP and is also weak to Stealth Rock, limiting the amount of switches it can make. Rotom-H is also viable in the Overused metagame, and while it is overshadowed by Rotom-W due to its Stealth Rock weakness, a handful more resists allows it to check threats that Rotom-W cannot like Serperior, Breloom, Thundurus, and Mega Scizor. It can take out Breloom and Bisharp with a STAB Overheat, something that Rotom-W is not capable of doing. However, due to its Rock weakness, it cannot check Ground-types like Rotom-W can and faces competition from Heatran as a defensive Fire-type, although Rotom-H can distinguish itself thanks to Levitate, access to Thunder Wave which can cripple Pokémon like Volcarona and Mega Charizard Y, Pain Split for a form of recovery, and Volt Switch which allows for it to act as a pivot for teams and gain momentum.
Rotom-Mow (or Rotom-Cut) resides in the RarelyUsed (RU) tier. It has a solid typing that gives it a scary STAB combination and offers resistances to Water and Electric attacks. Rotom-C has a solid base 105 Special Attack, which lends itself to a Choice Scarf set that can revenge kill weakened sweepers with Leaf Storm or Thunderbolt or a Choice Specs set that can punch holes through defensive Pokemon. Rotom-C does suffer from having a limited movepool that does not give it much leeway against Grass-types that resist Rotom-C's STAB combination. Rotom-C also cannot run defensive sets as it is outclassed in that regards by Tangrowth and Venusaur. Rotom-C also makes for a great choice in the Underused tier. It is capable of handling many of the bulky Water-types that are omnipresent in UU, and it can break through Ground-types like Nidoqueen with Leaf Storm. Its best sets are a Choice Specs set that can switch in easily to Water-types and immediately threaten them, a Choice Scarf set that remedies Rotom-C's rather lackluster 86 Speed, and a Bulky Attacker set that does not restrict Rotom-C to a Choice item while maintaining utility.
Normal Rotom resides in the NeverUsed (NU) tier, where it stands out as one of the best Pokémon in the tier. Rotom's unique Ghost/Electric typing and Levitate give it resistances to Flying-, Steel-, and Electric-type attacks while granting immunities to Normal, Fighting, and Ground attacks. Rotom can hit the prominent Psychic-type Pokemon with a super effective STAB Shadow Ball, and it can perform the role of pivot with Volt Switch or cripple its switch-ins with Will-O-Wisp or Trick. Rotom's best sets are its Spell Tag Hex set that lures in Pokemon immune to Electric and beat them handily, its Choice Scarf set that allows it to revenge kill Pokemon like Archeops and Tauros, a Choice Specs set that gives Rotom a considerable boost in power, and a defensive set that takes advantage of Rotom's great typing to check top tier threats. Rotom's biggest flaw is its relative lack of power due to low base power moves and lack of great bulk to fully utilize its resistances to the fullest potential. Rotom is also viable in the Rarelyused (RU) tier with its good typing and decent Speed that allows for it to act as a nice status spreader in the tier. It can deal with walls like Mega Steelix and Alomomola while providing a nice check to threatening set-up sweepers like Fletchinder with its Substitute set that has Will-O-Wisp and Discharge to deal status and Hex to take advantage of statused Pokémon. However, it does suffer from being rather frail which makes its matchups solely dependent on resistances.
Rotom-Fan (or Rotom-Spin) resides in the NeverUsed (NU) tier. Rotom-S has a solid typing with good neutral coverage in the tier while having handy resistances to Fighting and Flying. It is best used as a lure in for Ground-types and surprise them with super effective coverage. Rotom-S's best sets are its Expert Belt lure set capable of also acting as a pivot for offensive teams, its defensive set that can handle strong physical threats such as Golurk and Torterra, and its Choice Scarf set that allows it revenge kill certain threats like Shell Smash Gorebyss and Archeops. Its biggest flaw is its weakness to Stealth Rock and the lack of a true strong Flying STAB with Air Slash being its only option. Rotom-S is also usable in the Rarelyused (RU) tier of competitive battling where its typing can allow for it to check certain threats like Fletchinder, Escavalier, and Scrafty. A good typing and ability to threaten defensive walls even without Special Attack investment contributes to Rotom-S's solid niche as a physically defensive Pokémon. It can handle the status absorbers in the RU tier like Gurdurr, Sigilyph, and Xatu, and is fast enough of a defensive Pokémon to burn and annoy opposing threats like Rhyperior and Bulk Up Braviary. However, Rotom-S lacks reliable recovery and is weak to Stealth Rock. Its typing allows for it to have common weaknesses to Ice and Rock, which can prove problematic, and its attacks are underwhelming in power.
Rotom-Frost resides in the PU tier as one of the biggest threats in the tier and is also a viable, albeit niche, option in the Neverused (NU) tier. Rotom-F has an amazing offensive STAB combination with the famed Ice/Electric coverage that allow it to make for a good late-game cleaner. Its access to Volt Switch and Trick can give it a pivot role while potentially crippling defensive checks. Rotom-F is best used with a Choice Scarf to bolster its base 86 Speed and perform the role of early game scout or revenge killer. Rotom-F can also be utilized with a SubSplit Life Orb set consisting of its STABs, Substitute, and Pain Split to heavily damage teams while maintaining some sort of longevity. Rotom-F's biggest flaw is its weakness to Stealth Rock that makes it easy to wear down and common weaknesses to Fire and Fighting. It also lacks a reliable Ice STAB as Blizzard is only 70% accurate and could miss at inopportune times. Rotom-F's speed sometimes is too slow, as it is outsped by many common threats in PU and NU tiers if without a Choice Scarf and many other users of Choice Scarf can outpace Rotom-F. Rotom-F is also usable in the Rarelyused (RU) tier, where its nice STAB combination and ability to check threats like Flygon come in handy. It can run a Choice Scarf set or a SubSplit set while having accurate Blizzards when paired up with Abomasnow. However, it suffers from having a bad defensive typing, shaky accuracy with Blizzard outside of hail, and inability to get past certain bulky Mega Pokémon that are immune to Trick.
