Pokémon Black & White (be warned: spoilers)

[Cshad]

Being a legendary doesn't make it any better than any other Pokemon (to assume that is absolutely stupid). All the Regis reside in UU or NU. Pokemon like Wobb and Garchomp are in the banned/broken tier (Ubers). Pokemon like Infernape, Tryanitar, and Jirachi play in the Uber tier relatively well (when used competently), and Tyranitar isn't exactly what you would call uncommon in that tier either.
