Mega Blastoise's low speed is a vulnerability
Mega Blastoise's low base Speed stat makes it susceptible to opponents setting up or attacking freely before it can act.
IfGeneral, particularly before Speed boosts from Shell Smash.

Setup Strategy
Convert defensive bulk into offensive momentum.
Leverage Mega Blastoise's natural bulk and lower pre-boost speed to safely absorb an attack and activate Shell Smash. This transforms it into an unstoppable late-game special attacker that outspeeds boosted threats.
Don't let Mega Blastoise's base speed mislead you. Its initial slowness isn't a weakness, but a tactical opportunity to set up a devastating sweep with Shell Smash, flipping the script on faster threats.
Understanding why low speed enables success.
Mega Blastoise typically suffers from low base Speed, making it susceptible to opponents acting freely. However, this 'vulnerability' enables a safe Shell Smash. Upon Mega Evolving, Blastoise gains a substantial Special Attack boost. A single Shell Smash then dramatically increases both its Special Attack and Speed. A Modest Mega Blastoise with maximum Special Attack investment reaches a formidable 260 Speed after Shell Smash, allowing it to outspeed fast threats like Mega Alakazam and even a Jolly Dragonite after it uses Dragon Dance. This potent combination of boosted speed and power allows it to one-shot bulky Pokémon, such as Silvally with Water Pulse, turning a perceived weakness into a powerful setup advantage.
