Strategies for Blastoise

Shell Smash Special Attacker Moveset & Best Build

Nature Modest (+SpAtk, -Atk)
EV Spread HP 4 / Sp.Atk. 252 / Spd. 252
Final Stat Values HP 155 / Atk. 93 / Def. 120 / Sp.Atk. 150 / Sp.Def. 125 / Spd. 13
Ability Torrent
Held Item Focus Sash
Moveset Shell Smash
Ice Beam
Flash Cannon

These values are from base stats and ideal EVs, excluding external factors.

This strategy focuses on Sp. Atk. and Speed, both of which can be sharply raised by the move Shell Smash. Focus Sash lends support, allowing it to definitively survive at least one attack even after the defensive drops of Shell Smash. This will cause its Ability Torrent to activate, making its Water-type moves even more fearsome.

When compared to a Cloyster with a similar attacking style, this build has the advantage of using Special instead of Physical attacks, so its damage output won't be affected by the Burn status. Blastoise also has a higher Speed, and after using Shell Smash, it's able to outspeed a Hydreigon with a Choice Scarf, a feat Cloyster cannot accomplish.

Alternate Move Choices

Hydro Pump For when you want an even stronger Water-type move.
Focus Blast Its accuracy is low, but useful against Steel types.
Aqua Jet Good for using when the opponent has a priority move.
Dark Pulse For using against Psychic and Ghost types. However, Mimikyu and Dragapult can be handled with other moves, so its usage priority is low.
Earthquake Best when used with a Rash nature, and its HP EVs moved into Attack. After using Shell Smash, it has a chance of taking down an HP/Defense focused Toxapex in 2 hits.

Choice Scarf Moveset & Best Build

Nature Timid (+Spd, -Atk)
EV Spread HP 4 / Sp.Atk. 252 / Spd. 252
Final Stat Values HP155 / Def. 120 / Sp.Atk. 137 / Sp.Def. 125 / Spd. 143
Ability Torrent
Held Item Choice Scarf
Moveset Water Spout
Ice Beam
Dark Pulse

These values are from base stats and ideal EVs, excluding external factors.

To overcome Blastoise's low Speed stat, a Choice Scarf can be used to boost its Speed by 50%. The EVs of this build are stacked to allow it to attack first, even against the fastest possible Dragapult build.

Also, using the move Water Spout early on is a powerful strategy. Although the move's power depends on the user's current HP, the move's power is fixed at 150 when the Pokemon is Dynamaxed. You can then Surf in its place after Dynamax ends and its HP is dropped.

Alternate Move Choices

Dragon Pulse For using against Dragon types. Can hit a wide variety of opponents and useful for lowering the opponent's Attack as Max Wyrmwind.
Aura Sphere For hitting Dark and Steel types. However, it's ineffective against Ghosts, and Max Knuckle's Attack boost is useless for this build.
Flash Cannon Mainly for hitting Fairy types. Also good for boosting Defense as Max Steelspike.

How to Use Blastoise Effectively

Use Shell Smash at the Start of Battle

Shell Smash will sharply raise the user's Attack, Sp. Atk, and Speed stats. With a wide variation of moves both Physical and Special, you can focus on whichever suits your party best, and keep opponents guessing.

Even if Blastoise takes damage before or after using Shell Smash, this can allow its ability, Torrent, to activate and power up its Water-type moves.

An attacker that can also defend

As it has higher than average defensive stats in both Physical and Special Defense, it can handle itself when fists are flying. And with only two weaknesses in Electric and Grass, it's hard to pull out a trump card against it.

Blastoise can use a variety of moves, both attacking and supportive, allowing it to play multiple potential roles in a party.

Counters for Blastoise

Use a type-advantageous Pokemon

We recommend using Pokemon that are strong against Water-types such as Electric and Grass-type Pokemon. Unless it uses Shell Smash, weakening its own defenses, it can be hard to get solid damage on Blastoise without a type advantage.

Defend with a Water-resistant Pokemon

A defensive Pokemon with a Water typing can handle Blastoise's Water moves effectively. Tanks like Milotic and Toxapex can use Haze to undo the effects of Shell Smash and level the playing field.

Some Pokemon can nullify the effects of Water attacks, allowing them to switch out onto Blastoise unharmed if you get a good read.

I think on first build they meant to write focus sash instead of focus band cause band potentially can survive a lethal blow at any health but that’s a chance. A focus sash only works if your full health but it’s a guarantee safety net for 1HKO
