UUBL

''The tiering predictions and theories done in this project are done through both algorithm and personal bias. I looked at each and every Pokémon, their typings, abilities and potential hidden abilities, stats, movepool, and how well they could utilize their tools and calculated how much each would be used in the metagame.''

''Most Hidden Abilties are unconfirmed and/or not finalized. They were chosen from a list of Proposed Hidden Abilities based on how much they'd make sense and fit the Pokémon based on their designs and PokéDex entries.''

UUBL (UnderUsed Banlist) is the banlist for UU and is not a playable tier. UUBL Pokémon are not OU by usage (i.e., they do not have above 4.52% usage in OU) but cannot be used in UU or NU.
