MetaMons competitive notes

Mega Greninja is a water/dark-type Pokémon whose base stats lean toward Speed — at 630 BST it is a legendary-grade total for competitive play, with top speed tier (base 142) and a mixed attacking profile. Its Protean 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 Greninja. Build around what Mega Greninja 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.
