Abilities
MetaMons competitive notes
Yamask is a ghost-type Pokémon whose base stats lean toward Defense — at 303 BST it is a low total for competitive play, with slow (base 30) and a special attacking profile. Its Mummy 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 Yamask. Build around what Yamask 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.
