Great typing, nice coverage, and decent bulk give Gastrodon a good matchup against many top-tier threats of Doubles like Incineroar, Mega Metagross, Tapu Koko, and Zygarde! Recover sets it apart from other bulky Water-types like Tapu Fini and Suicune, and Toxic is a nice option over Protect that cripples switch-ins like Chansey and Tapu Bulu. The given EV spread and a Relaxed nature allow Gastrodon to survive Landorus-T's Tectonic Rage and two Ice Beams from Life Orb Kyurem-B, and minimized Speed helps it function in Trick Room well. Fire-types like Incineroar and Volcarona are Gastrodon's best teammates because they scare off Grass-types and enjoy Gastrodon's Storm Drain. Grass-types like Kartana and Amoonguss are good teammates too, as they appreciate Gastrodon reliably beating Fire-types, while in return they threaten bulky Water-types like Tapu Fini and Suicune that can kind of ignore Gastrodon.
