As a reader, I've been practicing for over 25 years, focusing on using the universal symbolism to lead people to uncover knowledge and emotions surrounding the situations they feel uncertain of, rather than "prediction". I believe the cards are always positive, even if the truth is difficult, and while my style is candid, it is also compassionate.
I read tarot in the RWS or Marseilles traditions, will use Lenormand for concrete questions, and enjoy adding a fun last touch with Edward Gorey's Fantod deck, if people want it.
