MetaMons competitive notes

Mega Aggron is a steel-type Pokémon whose base stats lean toward Defense — at 630 BST it is a legendary-grade total for competitive play, with slow (base 50) and a physical attacking profile. Its Filter 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 Mega Aggron. Build around what Mega Aggron 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.
