STABmons

“STABmons is an Other Metagame based on OU with one simple change: Pokémon now learn all moves that match their typing. Eevee, a Normal-type, has access to every Normal move in the game plus all the regular moves it learns naturally. This access to moves continues with evolution, so Sylveon, a Fairy-type Pokémon that evolves from Eevee, now learns all Fairy and Normal moves.” -Smogon.com
