Iron Moth is a powerful cleaner that is frequently able to snowball quickly with Fiery Dance, enabling it to break past would-be checks such as Gliscor and Landorus-T. Iron Moth uses Energy Ball to hit Water Types like Alomomola and Hisuian Samurott; it could also use Psychic to hit Toxapex and Mega Venusaur. It also has access to Dazzling Gleam to hit Dragon-types such as Raging Bolt, Garchomp, and Mega Latios; alternatively, Iron Moth could use Substitute. This allows Iron Moth to dodge status moves from Gholdengo and Galarian Slowking, as well as blocking priority from Kingambit and Raging Bolt. Iron Moth has 132 EVs invested into Special Attack to allow its Special Attack stat to be one point less then its Speed stat. This allows Iron Moth’s to get a Speed boost from its Booster Energy. Iron Moth could use other items if it is paired with Tapu Koko; for example, Heavy Duty Boots help to preserve its longevity.

Iron Moth is often inconsistent, as it struggles against common Pokemon such as Heatran, Ting-Lu, and Mega Tyranitar and is weak to Stealth Rock, meaning it functions best on hyper offense structures. Great Tusk is an excellent partner, as it can take out Heatran and Mega Tyranitar for Iron Moth and can remove entry hazards. Iron Moth appreciates other Pokemon with Rapid Spin like Terapagos and other forms of hazard prevention like Hatterene and Mega Diancie. Iron Moth also values teammates like Volcarona and Raging Bolt, as they share checks like Mega Tyranitar, Heatran, and Ting-Lu. Iron Moth matches up well into Ferrothorn, Corviknight, and Gholdengo, making Pokemon that have a poor matchup into them good partners. Tapu Lele, which can block priority using Psychic Surge, and Ogerpon-W, which breaks past Pokemon like Alomomola and Heatran, specifically enjoy Iron Moth’s presence on their team, as they all struggle with these foes. Iron Moth also values Stealth Rock to make it harder for its checks, like Mega Tyranitar, to switch in. Mega Diancie and Landorus-T both are able to set and deny hazards while doing significant damage before they faint through Endeavor and Explosion, respectively. Tapu Koko is another great partner for Iron Moth, as it can set Electric Terrain; this makes Iron Moth less reliant on Booster Energy to outspeed foes such as Mega Lopunny and Zamazenta. Tapu Koko can also offer valuable support by setting up dual screens; these let Iron Moth take hits from Pokemon like Booster Energy Iron Valiant and Terapagos variants lacking Earth Power that could take an attack from or outspeed Iron Moth.

With its unique typing, Iron Moth provides both offensive and defensive utility for balance and bulky offense teams, handling Steel- and Fairy-types such as Ferrothorn, Choice Specs Iron Valiant, and Gholdengo. Fiery Dance is preferred over other Fire-type moves due to the boosts given, which make Iron Moth a stronger wallbreaker and allow it to push past Pokemon such as Landorus-T and Moltres. Sludge Wave is necessary to hit Fairy-types such as Clefable, Iron Valiant, and Tapu Lele while also being a strong option against Fire-resistant foes such as Hisuian Samurott, Raging Bolt, and the aforementioned Moltres. U-turn allows Iron Moth to keep up momentum for its team, punishing defensive switch-ins such as Heatran and Toxapex more easily while enabling other strong attackers. Morning Sun improves Iron Moth's longevity, letting it wallbreak more consistently. Alternatively, Toxic Spikes punishes passive play against Iron Moth while wearing down defensive structures, including Pokemon such as Mega Tyranitar and Ting-Lu, quicker for its teammates. Energy Ball is another option, notably 2HKOing Alomomola unboosted while OHKOing Mega Diancie and Great Tusk after Stealth Rock, preventing the latter from using Rapid Spin. However, it doesn't have much use outside of this, since its damage output against other threats is poor without boosts.

Iron Moth works best on bulky offense teams that appreciate its pivoting and wallbreaking capabilities. Specially defensive Pokemon such as Galarian Slowking, Ting-Lu, and Mega Tyranitar all easily shut down Iron Moth, with the latter being able to Pursuit trap it with ease. Physically offensive partners such as Urshifu-R, Garchomp, and Weavile are valuable teammates that can break past these walls for Iron Moth. They all appreciate Iron Moth handling Fairy-types such as Clefable and Tapu Fini in return, as well as absorbing Toxic Spikes from Toxapex and Glimmora to improve their longevity. The aforementioned Garchomp, as well as Landorus-T and Ferrothorn, can set entry hazards such as Stealth Rock to help wear down defensive structures quicker, which allows Iron Moth to clean up more easily with its high Speed. If Iron Moth uses Toxic Spikes, it can even stack hazards with these teammates; this makes Gholdengo a good partner with its ability to deny Defog and Rapid Spin, as well as its ability to handle Psychic-types such as Tapu Lele and Mega Medicham. A major roadblock for Iron Moth is Heatran, which effectively counters Iron Moth. Ground-, Water-, and Fighting-types such as Great Tusk, Ogerpon-W, and Zamazenta are good allies for breaking past it with ease. In return, they appreciate Iron Moth handling bulkier foes such as Clefable, Ferrothorn, and Pecharunt. Pivot support from teammates such as Choice Scarf Urshifu-R, Roaring Moon, and Tapu Koko are great for enabling Iron Moth against foes it does well against but may not want to directly switch into, such as Melmetal and Kartana, while Iron Moth can enable these threats against foes it struggles versus, such as Heatran, Raging Bolt, and Toxapex. Tapu Koko is especially good since it enables Iron Moth's Quark Drive via Electric Surge, allowing Iron Moth to OHKO both Hisuian Samurott and Urshifu-R with Sludge Wave or OHKO bulky Gholdengo with Fiery Dance unboosted. Tapu Lele is also a solid teammate, threatening Toxapex and Ting-Lu for Iron Moth while giving immunity to priority from Urshifu-R and Kingambit, both of which would otherwise pick off Iron Moth after minimal chip damage. In return, Iron Moth breaks through bulky Steel-types such as Mega Scizor and Ferrothorn, while they can both overwhelm a shared check in Heatran.
