I use reversals if the artwork allows me. I find it helps to clarify what I am specifically "blocking" in a given situation and that helps to clarify my thinking. With reversed courts it gives me a clearer hint at the mood or intent of an individual I may encounter.
I believe all of the cards have a negative and positive message upright or reversed which is further enhanced depending on how it falls in a layout. And sooo many additional meanings!
The card's creator gives a hint - do they include meanings in the LWB that comes with the deck? If so, they've created the deck to be used with reversals included.
But I agree, it is all in what you feel comfortable with. Go with your gut - your personal High Priestess. hehe - Sea
