Con il suo Special Attack titanico e la sua Speed superba, Iron Moth è un potente cleaner e ottimo wallbreaker in grado di portare a casa le partite dopo un singolo potenziamento di Fiery Dance, oltre a offrire ai team offense una soluzione per assorbire le Toxic Spikes rilasciate da Glimmora. Dazzling Gleam permette ad Iron Moth di colpire duramente Dragonite, Dragapult e Zamazenta riducendo la sua dipendenza dal fenomeno Teracristal. Energy Ball è un'altra forte opzione di coverage che bersaglia Garganacl e i tipi Water bulky come Alomomola e Dondozo; similmente a Dazzling Gleam, dà a Iron Moth ottima coverage contro Great Tusk e Hisuian Samurott. Psychic è una coverage persino più forte per Zamazenta, che oltre a colpire superefficacemente Clodsire e Toxapex senza che Iron Moth faccia uso del fenomeno Teracristal. L'eccellente combinazione di STAB di Iron Moth è complementata alla perfezione da Tera Blast di tipo Ground, dando così ad Iron Moth la sua opzione più forte contro Galarian Slowking e Clodsire e impedendo che venga annullato da Heatran e Skeleridge. Tera Blast di tipo Ghost può essere usata similmente per colpire Galarian Slowking e Skeleridge oltre che Dragapult.
Substitute helps Iron Moth avoid Kingambit's Sucker Punch and Raging Bolt's Thunderclap while also vastly improving its matchup against Galarian Slowking, whose pivot set is unable to break Iron Moth's Substitute without relying on Future Sight, and Garganacl, which cannot break Iron Moth's Substitute with Salt Cure after it Terastallizes. Iron Moth can instead opt to run a 4 attack set; with Tera Blast Ground and Dazzling Gleam, Iron Moth maximizes its coverage while still hitting Dragon-types like Dragapult and Dragonite for super effective damage. Combining Dazzling Gleam and Energy Ball alleviates Iron Moth's reliance on Tera, although this leaves it completely walled by both Heatran and Skeledirge. With 124 Def / 132 SpA / 252 Spe, Iron Moth's Booster Energy gives it a Quark Drive boost to its Speed; the remaining EVs maximize its Special Attack while 124 Defense EVs help patch up its poor Defense, allowing it to survive a Sucker Punch from Kingambit with 5 Supreme Overlord boosts and a Close Combat from +2 Iron Valiant. A fully offensive spread of 4 Def / 252 SpA / 252 Spe is also an option to gain a Special Attack boost from Booster Energy, allowing it to overhwhelm checks like Galarian Slowking and Toxapex more easily, and is especially fitting on Sticky Web teams that can compensate for the lack of Speed boost. Tera Fairy powers up Dazzling Gleam into an additional STAB option that OHKOes Dragapult and Hisuian Samurott, along with securing a 2HKO on max HP Zamazenta and Dragonite through Multiscale, while defensively, it provides a resistance to Sucker Punch from Kingambit. Tera Grass can alternatively be used to strengthen Energy Ball, nailing the OHKO on both Great Tusk and Hisuian Samurott, while defensively granting Iron Moth a resistance to Ground-type attacks such as Gliscor and Landorus-T's Earthquake that can allow it to simply attack or set up a Substitute for free, a quality that is also appreciated against Alomomola. Defensively, Tera Ground gives Iron Moth an immunity to Raging Bolt's Thunderclap and both Galarian Slowking and Dragapult's Thunder Wave. Tera Ghost provides an immunity to Dragonite's Extreme Speed, Blissey's Seismic Toss, and Great Tusk's Rapid Spin in a pinch, with this option pairing well with Substitute to help mitigate its weakness to Kingambit's Sucker Punch.
