This system is useful in clarifying a relationship between 2 ppl when they are both interested in examining what is happening on unconscious levels. This might mean discovering special qualities of the relationship that both have been unaware of, for example. Two partners can play this game in many various situations. Disagreements can be settled, if both partners are prepared to view the question from a new perspective. It is useful to have a 3rd person there who is well acquainted with the Tarot.
