I really enjoy the variety of different deck options available through the Labrynthos app. However I noticed that several of the decks express that they represent different traditions: RWS, Marseille, Thoth. Something I noticed was that some of the decks (the Arcana Iris Sacra Thoth deck in this instance) had some different cards in the major Arcana, and different meanings for those cards. However, there is no explanation for the changes and whether they are because of the tradition associated with the deck, or other reasons. I feel that this is important part of the lessons that are trying to be taught, that different decks may have different meanings based in the tradition, or perhaps the interpretations by the deck authors.
