Composition

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.

This metagame is run by in the hills and a council. You can discuss strategies with friends in the Other Metas room on the simulator or in the main thread on the forums.

Play Restrictions

All standard OU clauses apply, plus:
Sleep Moves Clause: All sleep-inducing status moves, including Yawn, are banned.
Generation Jumping, or transferring moves from one generation to the next due to type changes, is allowed, unlike previous generations. However, it only works for moves that a Pokémon could've gotten in that generation. For example, Clefable can use any Normal-type move introduced in Generation 5 or prior, but it cannot use moves introduced Generation 6 or above, like Boomburst.
A Pokémon must be able to learn its new moves outside of battle similar to learning a TM. This means that some formes don't transfer their types backward since they cannot learn TMs outside of battle. For example, Galarian Darmanitan-Z does not transfer all Fire-type moves to regular Galarian Darmanitan, and thus Galarian Darmanitan cannot use any Fire-type moves it doesn't already know.
