Heat Crash gives Gouging Fire a powerful Fire-type STAB move, reaching its maximum Base Power against common foes like Chien-Pao, Ogerpon, and Gholdengo. Flare Blitz can instead be used for more consistent damage into heavy foes like Iron Hands and Terastallized Raging Bolt at the cost of significant recoil damage.
Breaking Swipe allows Gouging Fire to cripple opposing physical attackers, such as Ogerpon and Iron Hands, while dealing sizeable chip damage, particularly against opposing Dragon-types like Raging Bolt and Roaring Moon that resist Heat Crash.
Howl enables both Gouging Fire and common physical partners offensively, allowing them to sweep while offsetting the Attack drop from Intimidate.
Burning Bulwark can heavily punish physical attackers targeting Gouging Fire with a burn, most notably Fake Out from the likes of Iron Hands and Rillaboom. However, Burning Bulwark doesn't block status moves, so it can be bypassed by foes like Incineroar and Amoonguss with Parting Shot and Spore, respectively. Due to this, Protect is a viable option to mitigate this vulnerability.
Booster Energy activates Protosynthesis to give Gouging Fire a vitally important boost to Speed, allowing for it to outspeed the majority of the metagame, most notably Chien-Pao and the Ogerpon formes. The Attack investment allows Protosynthesis to boost Speed while maximizing Gouging Fire's damage output. The remaining EVs are placed in HP.
Tera Fairy provides an immunity to Dragon-type moves, namely Draco Meteor from Raging Bolt, Dragon Energy from Regidrago, and Breaking Swipe from both Roaring Moon and opposing Gouging Fire, while also letting Gouging Fire resist Fighting- and Dark-type moves from the likes of Iron Hands, Chien-Pao, and Chi-Yu.
Gouging Fire is best utilized as a support piece for physical attackers, using its offensive and defensive support tools to enable them. However, Gouging Fire can lack immediate damage output, particularly against heavy foes that take minimal damage from Heat Crash, so it's important to position partners to maintain strong offensive pressure throughout the game.
Gouging Fire is seriously threatened by special attackers, namely Landorus, Raging Bolt, and Glimmora; thus, it greatly appreciates partners that can improve its survivability through damage reduction or healing to help alleviate such pressure. Namely, Grimmsnarl and Alolan Ninetales can set dual screens to reduce the damage of opposing attackers, and Rillaboom and Sinistcha can provide healing with Grassy Surge and Hospitality, respectively.
Chien-Pao pairs phenomenally with Gouging Fire, as it can threaten Landorus and Raging Bolt for Gouging Fire while bolstering its damage output with Sword of Ruin. In return, Gouging Fire can threaten the opposing Steel- and Ice-types that resist Chien-Pao's Ice-type STAB moves like Kingambit and Alolan Ninetales while furthering Chien-Pao's offensive presence with Howl. Landorus can threaten Diancie and Incineroar for Gouging Fire, which hits Ice-types like Chien-Pao for Landorus. Dragonite is a powerful recipient of Howl, particularly for boosting the power of Extreme Speed, and Dragonite can pivot into Ground-type moves like Earth Power from Landorus.
Ogerpon-W and Rillaboom also greatly benefit from Howl while providing Gouging Fire support in the form of redirection and Fake Out, respectively. In the case of Ogerpon-W, it also threatens common checks to Gouging Fire in Landorus and Glimmora and offers a way to remove Incineroar. Ting-Lu is able to shore up Gouging Fire's weaker special bulk, while Gouging Fire can reduce physical damage through Breaking Swipe and Burning Bulwark, forming a potent duo defensively that can both deal sizeable damage, particularly when amplified by Howl. Gouging Fire greatly threatens Rillaboom, which can be problematic for both Ting-Lu and Ogerpon-W.
