MetaMons competitive notes

Meganium is a grass-type Pokémon whose base stats lean toward Defense — at 525 BST it is a strong total for competitive play, with above-average speed (base 80) and a mixed attacking profile. Its Overgrow 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 Meganium. Build around what Meganium 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.
