Yeah, I see a lot of people doing tarot readings for money but I don't see myself doing that.
I got into the tarot group because it's not so easy to find a therianthrope's guild!
From a scientific perspective there is a lot to say for randomness. Like the theory that the I Ching was a version of game theory from bronze age China. I recently created A System of Blessings with 13 selected characters from the I Ching because I wanted to give people something nice but didn't want to give everybody the same thing.
I found the tarot readings were infinitely better to the person getting the reading when I just forced the results. So I did.
I still did all the things you're indicating about talking about specific personality, etc, as the patter to the concept.
