PU Viability Rankings![]() Welcome to the XY PU Viability Rankings! Viability Rankings are a method of sorting Pokémon in a given tier based on how good they are in said tier. S rank is reserved for the defining Pokémon of the tier, while E rank is the place for unviable Pokémon that have no worthwhile use in the metagame. As the metagame changes, the rankings are periodically updated by players who are well-versed in the tier. Ranks are organized alphabetically. S RankA RankA+AA-B RankB+BB-C RankC+CC- |
