ADV OverUsed Metagame Primer
Composition
OU (OverUsed) is Smogon's fundamental tier. With the exception of Pokémon banished to the Uber tier, every Pokémon can be used in OU, including Pokémon from UU and NU. A Pokémon is considered OU based on community consensus at the time that ADV OU was the active generation.
