Garchomp leverages its good defensive typing and decent bulk to become a solid tank that checks several prominent Pokemon, including Mega Charizard Y, Heatran, and Volcarona. Toxic allows Garchomp to deal with Mega Charizard Y and bulky Volcarona while also punishing several Pokemon that would otherwise switch in easily, such as Great Tusk, Zamazenta, and Moltres. Protect allows Garchomp to rack up Toxic damage, keep itself as healthy as possible with Leftovers, and scout Choice-locked foes such as Choice Scarf Hisuian Samurott and Choice-locked Tapu Lele. Garchomp is a solid entry hazard setter, as it can pressure some common hazard removal options, most notably Great Tusk, Terapagos, and Zapdos, with Toxic. Dragon Tail is a good alternative if the team has other hazard setters, as it lets Garchomp rack up hazard damage and temporarily remove foes that might try to set up on it, such as Air Balloon Gholdengo, Swords Dance Gliscor, and Swords Dance Kartana. Leftovers allows Garchomp to stay healthy throughout the game and synergizes well with Protect, while Rough Skin punishes contact moves from the likes of Urshifu-R, Hisuian Samurott, and Great Tusk. The given EV spread allows Garchomp to best check special attackers like Mega Charizard Y and Volcarona, while the Speed EVs allow it to outrun Modest Heatran. 40 Speed EVs with a Jolly Nature let Garchomp outrun Raging Bolt, but the reduction in bulk makes Garchomp noticeably worse against Gholdengo and Heatran, and Garchomp can't safely switch into Raging Bolt anyway.

This Garchomp set fits well on offense and bulky offense teams, as it has limited longevity but provides these teams with much needed role compression in checking Mega Charizard Y, Heatran, and Volcarona while also setting up entry hazards. Garchomp does well supporting offensive teammates that dislike these specific threats, such as Gholdengo, Kingambit, and Kartana. Gholdengo is an especially good teammate, as it can deny hazard removal attempts from Terapagos and Zapdos, which is important as Garchomp has limited longevity and will likely not be able to repeatedly set up hazards in longer games. Alomomola is another solid teammate, as it can pivot into threatening physical attackers such as Great Tusk, Mega Lopunny, and Zamazenta that Garchomp cannot reliably handle, due to the frequency with which they run Ice-type coverage. It also can Wish pass to keep Garchomp healthy. Knock Off users such as Kingambit, Kartana, and Mega Scizor can remove Heavy-Duty Boots from the likes of Zapdos, Moltres, and Terapagos, therefore letting Garchomp's hazards make significant progress by themselves. Fast and powerful offensive teammates such as Tapu Koko and Zamazenta appreciate Garchomp taking a few strong hits from the likes of Mega Charizard Y, Gholdengo, and Heatran, and they can make up for Garchomp's lack of longevity by generating significant offensive pressure. The aforementioned teammates can also help revenge kill certain faster threats that Garchomp dislikes, such as Ogerpon-W, Kartana, and Mega Diancie.
