History[]
Originally, there were no fight formats, and cards were allowed to be used in any decks regardless of their clans. In fact, due to the small number of cards available at the time, some clans simply did not have enough cards to make a deck using only cards from their own clan. For example, the Great Nature clan was introduced in Booster Set 2: Onslaught of Dragon Souls, but no trigger units were released for it until Booster Set 7: Rampage of the Beast King, so clan mixing was until that point the only way to play the Great Nature clan in a deck. At the same time, many of the more powerful cards had clan-based restrictions as part of their abilities, such as a [Power] penalty for controlling a unit of a different clan, the Lord keyword, or an ability that could only be used on cards of the same clan or if you controlled another unit of the same clan. These restrictions, along with the rule that trigger effects require a unit of the same clan on the field to activate, made it so that clan mixing was rarely done.
With the introduction of the Legion mechanic in Booster Set 16: Legion of Dragons & Blades, the strategy of mixing clans suddenly became extremely powerful. To keep the power level of these decks under control, and to prevent further situations like this from occurring again, the Clan Fight regulation was implemented in February 2015. Clan-based restrictions within cards' abilities became unnecessary as a result, and soon afterward began to be no longer printed on cards. The Extreme Fight regulation was created at the same time so that players who wanted to play multi-clan decks could still do so; however, there have never been any official tournaments that have used the Extreme Fight regulation, and it is rarely played in practice.
