MetaMons competitive notes

Mega Meganium is a grass/fairy-type Pokémon whose base stats lean toward Special Attack — at 625 BST it is a legendary-grade total for competitive play, with above-average speed (base 80) and a special attacking profile. Its Mega Sol 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 Meganium. Build around what Mega 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.
