The following is a directory to all of the tiers from RBY to XY with all the special Clauses and bans as they are currently played. These are all tiers and metagames recognized by Smogon as official metagames. There are metagames and rulesets that have existed during Smogon's existence such as Pokemon Stadium LC and BW/XY Triples, but these have not been recognized by Smogon as part of either the official usage tiering or metagames to be played in official tournaments.
A couple of these tiers have seen intense tiering discussions on other sites, such as RBY2K10 and Mount Silver, particularly the lower tiers of older generations. Smogon recognizes these tiers as the most commonly played, and when hosting tournaments in their formats will use their banlists and rulesets. These are detailed below.
