The Swords represent the element of Air.

The Suit of Swords Tarot cards deal with the mental level of consciousness that is centered around the mind and the intellect. Swords mirror the quality of mind present in your thoughts, attitudes, and beliefs.  The Swords represent the qualities of intellect and rationality, but also to every achievement like culture, science, philosophy or any ongoing process that later ends up as ‘history’. This almost explains by itself why the Swords can be blessing and malediction the same time.

From their elemental dignities, Swords do not harmonize too well with Disks when the airy spirits have not much patience with the passive stillness of the Earth. The get along well with both Wands and Cups.
