It resembles it Zodiac name-sake as it looks like a scale holding the Sun on one side and the Moon on the other, representing the two different magics used to make the Clow Cards. The Sun represents Western Magic and the Moon represents Eastern Magic. It is one of the few cards never used in the manga or the anime, including The Wave and The Through. It is under The Earthy.
