MetaMons competitive notes

Grumpig is a psychic-type Pokémon whose base stats lean toward Special Defense — at 470 BST it is a typical total for competitive play, with above-average speed (base 80) and a special attacking profile. Its Thick Fat 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 Grumpig. Build around what Grumpig 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.
