MetaMons competitive notes

Mega Blastoise is a water-type Pokémon whose base stats lean toward Special Attack — at 630 BST it is a legendary-grade total for competitive play, with mid-pack speed (base 78) and a special attacking profile. Its Mega Launcher ability matters more than the raw numbers when it hits the field: check what it does before deciding between a sweeper, pivot, or support role for Mega Blastoise. Build around what Mega Blastoise actually threatens, not its in-game lore — start from its weaknesses and strongest STAB moves, then decide whether its Speed, bulk, or coverage justifies a team slot.
