Mage Knight - Commonly known as "Mage Knight 2.0", this Base Set was released in November 2003 and represented a major revision to the Mage Knight ruleset. Figures from prior sets remained compatible with this ruleset. Figures from the prior sets were phased out from tournament play. Figures released with Mage Knight 2.0 and later also included more features that enabled them to be more versatile and customizable on the battlefield, such as a wider variety of special abilities, subfactions giving units a more "permanent" ability, and proficiencies which gave warriors abilities based on their combat value types. One of the major enhancements with Mage Knight 2.0 was the introduction of styrene cards which influenced gameplay in various ways.
