Uber Competitive Class

The Uber tier is effectively a banlist for the OU tier, as "standard" battles include everything in the OU list and below. Pokémon in the Uber tier were deemed too powerful or destabilizing to the OU metagame to allow. Ubers, if allowed, cause extreme "centralization" of strategies—in other words, it is impossible or very difficult to counter them in a reasonable manner. The Uber tier may include any Pokémon, not necessarily just Legendary Pokémon. Typically, it includes all Legendary game mascots except Black Kyurem, due to various factors preventing it from becoming "too centralizing". Although many legendary Pokémon reside in the Uber tier, a far larger number exists in lower tiers due to similar inadequacies. After the release of Pokémon Omega Ruby and Alpha Sapphire, due to the dominance of Mega Rayquaza, Smogon made their version of Ubers a full-fledged tier, allowing bans from the tier. However, unlike other tiers, it is not affected by usage. As a result, Smogon also endorses a playstyle referred to as "Anything Goes", which has no fan-imposed rules other than the "Endless Battle Clause".
