Gastrodon's solid bulk and incredible defensive typing make it one of the better specially defensive walls and hazard setters in the tier. It's able to check Pokemon like Gengar, Iron Jugulis, and Kilowattrel and set up hazards against other hazard setters like Hippowdon and Sandy Shocks to help wear down Pokemon like Wo-Chien and Gallade. Stealth Rock should only be used as Gastrodon's hazard of choice if it cannot be fit onto another team member. Sludge Bomb and Ice Beam both help to take care of Grass-types like Wo-Chien and Tsareena. Ice Beam also serves as an effective way of hitting Dragon-types like Salamence, Noivern, and Haxorus. Surf can be used as an alternative to hit Hippowdon harder and force Talonflame out more reliably. Sticky Hold allows Gastrodon to absorb Knock Off from foes like non-Mold Breaker Tinkaton, Grafaiai, and Donphan, letting it maintain Leftovers recovery. Storm Drain is an effective alternative to absorb Water-type attacks from foes like Paldean Tauros-W and Tatsugiri while giving a boost to Gastrodon's attacks, though Gastrodon must Terastallize in order to handle the former's Close Combat. Heavy-Duty Boots prevents Gastrodon from getting worn down by hazards. Covert Cloak makes Gastrodon a hard counter to Grafaiai, and makes it able to answer Pokemon like Gengar and Iron Jugulis more reliably by ignoring secondary effects from their moves. Tera Poison removes Gastrodon's Grass weakness, gives it a valuable immunity to Toxic that lets it switch in on Quagsire's Toxic and Toxic Spikes, and powers up its Sludge Bomb, allowing it to 3HKO Brambleghast and 2HKO Tsareena. Tera Ghost lets Gastrodon spinblock Brambleghast and Tsareena while letting it wall Fighting-types like Slither Wing and Lucario, though it does become weaker to Gengar.
Gastrodon works best on hazard stack, balance, and bulky offense teams that appreciate its defensive utility. Stealth Rock setters like Tyranitar and Tinkaton allow Gastrodon to free up a moveslot to run Spikes. Gastrodon struggles greatly against Grass-types without Terastallizing, so Pokemon that can deal with them, such as Talonflame, Slither Wing, and Salamence make good teammates. Gastrodon struggles to handle strong wallbreakers like Lucario, Dragon Dance Salamence, and Pawmot, so it pairs well with Pokemon like Wo-Chien, Scream Tail, and Hippowdon that can check these breakers more reliably, though the former must Terastallize to do so. Wallbreakers like Choice Specs Gengar, Pawmot, and Scizor greatly appreciate the hazards that Gastrodon sets up, as it makes it easier for them to break through bulkier foes like Hippowdon and Quagsire.
