I've been reading tarot for 13 years now. I started off with the Mythic Tarot deck when I was 15 and I must say that it is a challenging deck to work with aand much harder to interpret than Rider Waite cards. Now I own Tarot de Marseilles, The Mythic Tarot, Original Rider Waite, Mini Rider Waite, Tarot of the New Vision, and Mini New Vision.
I prefer to work with the Tarot of the New Vision as they are modelled after RW cards but looking at each scene from behind, thus revealing a lot more info in each card due to the fact you can now see what the people on the cards are looking at. My friends often come to me for readings and claim that my readings came true. Now that makes me feel good!
Sometimes I use the cards in conjunction with counselling when requested and that gives awesome results and leaves the querant feeling great.
I thank God for the gift of being able to readily interpret Tarot cards. I've come a long way from 13 years ago as a beginner who had to refer to the book constantly.
