MetaMons competitive notes

Rillaboom is a grass-type Pokémon whose base stats lean toward Attack — at 530 BST it is a strong total for competitive play, with above-average speed (base 85) and a physical 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 Rillaboom. Build around what Rillaboom 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.
