OverUsed Viability Rankings
Welcome to the official ORAS OU Viability Rankings. We as a community will rank every single usable Pokémon into "tiers." The general idea of the topic is to rank each OU Pokémon under "rankings" that go in descending order. Since this is a general tier list, everything is lumped together. There won't be any segregation between offense and defense threats. For example, garchomp can be ranked in A tier as an offensive threat, Ferrothorn can be ranked under A as supportive threat, and Hippowdon can be can also be ranked in B tier as a defensive threat. These are just examples not representative of their future or current ranks.
The Pokémon are individually ranked alphabetically.
Rankings
- S Rank
- The best of the best. Reserved for Pokémon who shape and define the OU metagame and are a clear-cut above the rest of the tier. These Pokémon are typically very powerful offensive threats that are difficult to prepare for and/or are phenomenal support and defensive threats that provide significant utility or defensive potential, respectively. Also the home of Pokémon who can easily perform multiple roles effectively, increasing their versatility and unpredictability. If the Pokémon in this rank have any flaws, those flaws are thoroughly mitigated by their substantial strengths.
- A Rank
- Reserved for Pokémon who can sweep or wall significant portions of the metagame and can perform well against most play styles, but require some support or have some flaws that prevents them from doing this consistently. Supporting Pokémon in this rank may give opponents free turns or cannot create free turns easily themselves, but can still do their job most of the time. Pokémon in this rank are also known to define the play styles they fit on or are easy to add on any given team, while being able to carry their weight nearly every match.
- B Rank
- Reserved for Pokémon who cannot sweep through or wall significant portions of the metagame, but can properly fulfill a given offensive/defensive niche. Support Pokémon in this category have flaws that prevent them from doing their job, are setup bait for dangerous sweepers, or often give too many free turns. Pokémon who are partially outperformed or struggle with taking on the Pokémon in the A or S Ranks, but are otherwise dangerous in their own right and aren't difficult to fit on teams, may also fall into this category.
- C Rank
- Reserved for Pokémon who can be effective in the right setting, but either have crippling flaws that prevent them from consistently executing their strategy or are completely eclipsed by a Pokémon in the above ranks. Pokémon in this rank typically require more extensive support, struggle performing against the Pokémon ranked above, and are difficult to fit on teams.
