Muddy Water is a reliable spread move that can reduce the opposing side's accuracy.

How to Use Gastrodon Effectively

Use Gastrodon Against Top Pokemon

Gastrodon matches up favorably against Garganacl, Iron Bundle, and Gholdengo. Be sure to Terastallize wisely and use it only when necessary.

Use Gastrodon As A Win Condition

Gastrodon can outdamage Garganacl with Earth Power. With Covert Cloak, it is able to take no damage from Garganacl's Salt Cure residual damage. It can also heal itself with Recover, making it even harder to KO.

How to Build a Team with Gastrodon (West Sea)

Gastrodon enjoys defensive teams with teammates that are difficult to KO. Gastrodon itself can put a halt to hyper-offense, so it best synergizes with teammates with different types that can function similarly.

This Pokemon can win you games if you are able to run your opponents out of ways to hit it for meaningful damage.

Sample Doubles Team

Support	Special Attacker
Grimmsnarl	Iron Bundle
Physical Attacker / Tank	Special Attacker / Tank
Corviknight	Gastrodon (West Sea)

Grimmsnarl can provide Screens for its team and boost its overall defenses, as well as protect its partnered Iron Bundle from Status Conditions with Misty Terrain.
Iron Bundle matches up favorably against Grass-types and Ground-types, being an effective way to take out threats to Gastrodon.

Gastrodon enjoys the Screens support and Misty Terrain protection, and will comfortably take on the likes of Garganacl in the end game.

Corviknight also benefits from Screens, and can double as a tanky Physical Attacker that can take on other dedicated Attackers.

Counters for Gastrodon

Be Prepared for Gastrodon's Type

Gastrodon can pose a threat to your team and is countered by different Pokemon depending on whether it Teras or not. Always be ready with ways to hit it for super-effective damage, or at least deal more offense than Gastrodon can.
