The Sceptic's Tarot is about using Tarot cards for ideas, brainstorming, problem solving, decision-making, planning, goal-setting, motivation, self-exploration, creative activities, counselling, relaxation and more.
There is nothing mystical, esoteric or supernatural involved.
The cards are usually associated with divination. They do not have to be. The Sceptic's Tarot offers a different take on how Tarot cards can be used.
