Hello Theold...
I see your favorite deck is Alchemical.
Would you believe the "Gnostic" Tarot of the Saints might be mysterious?

While I think of the Buddhist Tarot as fairly straightforward, I don't find the Angel deck by Robert Place to be as straightforward...however I do like his books and decks. The pips are not illustrated and seem like playing cards, but the angels and courts are plentiful in terms of meanings in a slim, good book.
My next suggestion would be a deck where I love the clear colors and ink and watercolor wash beauty--both Italianate clarity in coloring and mysterious in terms of soft inspiration and also odd shadowy cards as well...this seems to be a deck of people who returned from war, walking in country landscapes, encountering travelling muscians, storytellers, inns and courtyards...the little white book gives some interesting meanings that allow for great readings, at least in my opinion...
And the majors and some of the scenes remind one of other painters who did interiors or sky/landscapes...like Dutch masters, the Romanticists...but there are warriors and musicians in relatively equal number to courtly figures. I also see correspondence to fairy tales...not many animals or children though, in the scenes...and you can see the Five of Pentacles and Ten of Swords on the left hand side, lower row are not the typical Rider Waite standard scenes of misery or nightmare...

I'm going to revive a thread on this deck soon, as I'm trying to write up a journalized study of this deck...some of my majors in a review have some garbled sentences, unfortunately...
