How to Use Blastoise Effectively

Use Shell Smash at the Start of the Battle

Blastoise is one of the few bulky attackers that have Shell Smash, so it's important that you use this boosting move at the start of the battle so that you can deal as much damage as possible to the opposing team.

Since this boosting move also increases Attack, your opponent may second guess your Blastoise and may struggle to switch into the right defensive Pokemon.

A Bulky Attacker

Blastoise has great mixed bulk and its Mono Water-typing gives it only two weakness - Grass and Electric.

Even with little to no defensive EV investment, Blastoise can withstand weaker attacks and stay in matches between opponents longer. It can also run defensive and supportive sets, allowing it to fill multiple roles in a party.

How to Build a Team with Blastoise

Blastoise great bulk and ability to run offensive and support builds make it a versatile Pokemon. While it faces stiff competition from stronger Water-types, it has a niche in more balanced teams - especially those that make use of a Grass-Fire-Water Core.

A Dynamax Lead for Hyper Offense Teams

Access to Shell Smash and great natural bulk make Blastoise a great Dynamax or Gigantamax Lead for offensive teams. It's best used with Grass and Fire-types as these three cover each others weaknesses and gaps in coverage.

Example Grass-Fire-Water Offensive Team

Lead Dynamax	Offensive Pivot	Physical Attacker
Blastoise	Incineroar	Rillaboom

Blastoise fills the role of both lead and special attacked for this Grass-Fire-Water Team, with Incineroar filling the role of an Offensive Pivot while Rillaboom is a straightforward physical attacker.

Since it's partnered with a Fire-type Pokemon, it's best to Gigantamax Blastoise so that its Water-type moves becomes G-Max Cannonade and doesn't set up rain that can lower Incineroar's Fire-type moves.

Incineroar functions as an offensive pivot and deters Grass-types that can easily switch into Blastoise's moves.

Rillaboom on the other hand helps round off the gaps in coverage by providing strong, physical Grass-type moves. It also sets up Grassy Terrain with its Grassy Surge Ability, which is very useful for pure offensive teams since it recovers the team's HP at the end of every turn.

A Special Attacker for Rain Teams

Blastoise is also a great choice for special attacker in Rain Teams since it can heavily damage the opposing team with high-powered Water Spouts.

Example Rain Team

Lead Weather Setter	Choice Scarf	Offensive Pivot
Pelipper	Blastoise	Tornadus (Therian Forme)

This balanced Rain Team relies on Pelipper to set up Rain Dance with its Drizzle Ability, with Blastoise filling the role of a Special Sweeper while Tornadus functions as an offensive pivot.

Blastoise works well with Tornadus as the latter helps deter Grass-types that can withstand even boosted Water Spouts.

Both Pokemon benefit from Pelipper's Rain, with Blastoise's Water Spouts getting a power boost while Tornadus' Hurricane gets 100% accuracy.

How to Build a Weather Team

A Bulky Support Pokemon in Doubles

Access to utility moves such as Fake Out, Helping Hand, and Life Dew - on top of its great mixed defenses, make Blastoise a great support Pokemon in Doubles and is easy to fit into many types of teams.

Example Balanced Doubles Team

Physical Attacker	Devensive Pivot / Support
Dragonite	Blastoise
Special Sweeper	Follow Me Redirection Support
Gengar	Togekiss

In this sample team, we partner Blastoise with Dragonite who benefits from its Life Dew to keep it healthy and ensure that its Multiscale Ability stays active throughout the match.

Blastoise can also scout the opposing team using Fake Out, or boost Dragonite's power with Helping Hand. Since Double Battles are very fast paced, Dragonite often doesn't have a chance to boost with Dragon Dance, so the 50% boost from Helping Hand goes a long way!

Gengar and Togekiss are the backup sweeper and redirection support for this team respectively. Gengar also benefits from Blastoise's Life Dew since its Poison-typing lets it freely switch into Fairy-types that target Salamence.

Meanwhile, Blastoise can use Flip Turn to quickly pivot to Togekiss if Dragonite requires redirection support.
