NOTE: Includes the main tiers Uber, OU (Over-used), UU (Under-used), RU (Rarely-used), NU (Never-used). While Pokemon can be used in higher tier than they are assigned, just that one tier is accepted (so Serperior would be just NU, not all of the tiers).
This information is as of May 30, 2012 according to their tiers in B/W. If any of this information has changed leave a comment about it.
