In tarot, the suit of Swords can be associated with both Air (Creative Mind) and Fire (Powerful Intellect), depending on the tarot system one prefers. Personally, I see the suit of Swords as Fire in the imagery of rapidly firing neurons in the brain. The thinking, creating, working brain 'lights up' with the Spirit of Fire.
For those of uncommon mind and spirit, the Witches Tarot (Ellen Cannon Reed, Martin Cannon) has Swords associated with Fire and Wands with Air, rather than the more common Wands/Fire and Swords/Air. The Intuitive Tarot also has swords/fire/intellect and rods/air/creativity. A few of the other tarot decks having Swords/Fire and Wands/Air are the Celtic Dragon Tarot, Dreampower Tarot, Legend: Arthurian Tarot, Shapeshifter Tarot and Butler Tarot.
