MetaMons competitive notes

Omastar is a rock/water-type Pokémon whose base stats lean toward Defense — at 495 BST it is a typical total for competitive play, with slow (base 55) and a special attacking profile. Its Swift Swim 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 Omastar. Build around what Omastar 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.
