MetaMons competitive notes

Lairon is a steel/rock-type Pokémon whose base stats lean toward Defense — at 430 BST it is a low total for competitive play, with slow (base 40) and a physical attacking profile. Its Sturdy 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 Lairon. Build around what Lairon 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.
