The Osho Zen deck has given me some great readings.
In a way, I did start out with the Osho Zen deck, even without prior knowledge of tarot. I used to go on the Osho Zen website and get those online readings there. I didn't even know they were tarot cards!
But the illustrations and keywords on the cards made everything easy to read with. I never thought I'd get into tarot though, yet here I am years later, with a physical copy of the Osho Zen deck in my hands.
The only trouble are probably courts, since they go by like a compass direction that are symbolized by arrows. I think this is how it goes: Kings are North ^ Queens are South v Knights are East < and Pages are West > And I hope I got that right. They do get confusing!
The deck kind of goes in it's own direction, like the Aces are the highest card in the minors (at least they keep reading that way) and are depicted as having a blank symbol instead of a number or something saying Ace. There is also an extra major card called The Master, that also has a blank symbol. And the suits are different from the ones in traditional tarot. But if you've read Osho books and know his teachings, then I'm sure you'll like the deck itself.
