Blastoise is a solid check to strong physical attackers like Darmanitan and Barraskewda capable of supporting its teammates with entry hazard removal in Rapid Spin. Ice Beam allows Blastoise to punish Noivern and Grass-types like Roserade. Toxic punishes opposing Water-types like Rotom-W, Heliolisk, and Milotic, which Blastoise is unable to effectively punish otherwise. Rest alongside Sleep Talk is an option over Ice Beam and Toxic to improve Blastoise's longevity without making it be overly passive; however, it leaves it easily taken advantage of by the aforementioned Dragon-, Grass-, and Water-types. A Bold nature with maximum Defense investment allows Blastoise to check foes like Darmanitan better. If needed, Blastoise can invest 96 Speed EVs in order to outpace threats like Adamant Pangoro and cripple them with Toxic or a potential Scald burn.
Noivern is able to offensively check foes like Roserade, Celebi, and Heliolisk that give Blastoise trouble and can bring it in against common entry hazard users like Gigalith and Rhyperior with U-turn, which Noivern can opt for more easily over Defog with Blastoise fulfilling the role of an entry hazard remover. Celebi and Roserade are able to take on Electric-types like Rotom-W and Heliolisk as well as offensively pressure bulky Water-types like Milotic and Jellicent for Blastoise. Sylveon is able to provide Blastoise with both Wish and Heal Bell support to greatly improve its longevity and pivot into Noivern for it. Similarly, Umbreon can provide the same support but it can also switch into strong Grass- and Electric-types like Celebi and Heliolisk. Blastoise also appreciates Umbreon and Sylveon's ability to wake it up if utilizing Rest, making it less reliant on Sleep Talk. Galarian Galarian Weezing can take on strong Fighting-types like Machamp that take advantage of Blastoise. Incineroar is able to pivot into foes like Chandelure and Reuniclus and ease the matchup against the aforementioned Steel-types for Blastoise, while the Rapid Spin support Blastoise provides helps it pivot into foes like Escavalier without as much fear of being punished by entry hazards if it loses its Heavy-Duty Boots to a Knock Off. Escavalier, Doublade, and Bronzong make for great partners, as they can take on strong Psychic-types like Gardevoir, Necrozma, and Reuniclus as well as Grass-types like Celebi that Blastoise struggles to punish. In return, Blastoise can pivot into strong Fire-types like Incineroar and Darmanitan for them. Choice Specs Chandelure is able to take advantage of the aforementioned Psychic-types as well as remove Grass-types like Roserade and Tsareena for Blastoise. In return, Blastoise can provide it with crucial support in entry hazard removal and wear down Chandelure's best defensive checks like Gigalith, Incineroar, and Milotic.

After a Shell Smash, Blastoise becomes a fearsome late-game sweeper with its ability to outpace a majority of the boosted metagame and its Special Attack being boosted to great levels. Ice Beam provides Blastoise with the necessary coverage to OHKO Dragon- and Grass-types like Noivern, Celebi, and Roserade. Focus Blast is the strongest coverage option it can run to help break past Pokemon like Umbreon and Rotom-W and OHKO Heliolisk. Aura Sphere is a more reliable option that still guarantees the OHKO against Heliolisk; however, it greatly hinders Blastoise's ability to break through foes like Rotom-W. Dark Pulse gives Blastoise super effective coverage to break through Jellicent, which would otherwise wall it, but it doesn't hit much else outside of this matchup. White Herb prevents it from being revenge killed as easily, especially by strong First Impression users like Golisopod and Sirfetch'd, while potentially giving Blastoise another opportunity to set up an additional Shell Smash. Life Orb is an alternative option that greatly amplifies Blastoise's damage output, allowing it to OHKO offensive Rotom-W and 2HKO Milotic with Focus Blast. A Timid nature is an option to outspeed Choice Scarf Heliolisk after a Shell Smash, but it greatly cuts into Blastoise's offensive capabilities.
Dual screens support from the likes of Espeon and Xatu allows Blastoise to safely set up one or multiple Shell Smashes more easily. Xatu can also bring Blastoise in safely with Teleport against foes like Incineroar and Rhyperior to set up. Toxtricity is a fantastic partner, as it can remove Grass- and Water-types like Milotic and Celebi for Blastoise as well as offensively pressure opposing Electric-types like Heliolisk and Rotom-C for it. Toxtricity is able to bring in foes like Gigalith and Rhyperior that Blastoise can set up on. Other wallbreakers like Swords Dance Incineroar and Lucario are able to break through Blastoise's defensive checks like Umbreon and the aforementioned bulky Water-types for it to clean late-game. Cobalion is able to beat Umbreon for Blastoise as well as provide Stealth Rock support to help it guarantee OHKOs against foes like Celebi after a Shell Smash. Similarly, Alolan Dugtrio can provide Stealth Rock support and remove Electric-types like Heliolisk and Toxtricity for Blastoise. Alolan Dugtrio can also provide Memento support to help Blastoise set up a Shell Smash more easily. Dragon Dance Necrozma appreciates Blastoise's ability to break through its common checks like Incineroar, Umbreon, and Rhyperior.
