Oh what a wonderful thread! I have lots of Lo Scarabeo decks, and most of them were bought as part of the partwork. Thereby I got decks that I would not have bought in any other circumstances.
But some of these decks actually caught my attention after I had examined its imagery and history. So now my favs are:
Tarot of the 78 Doors - all times favourite. It was among my first decks and now looks a bit shabby, so I've bought another one for later. It gives very accurate readings.
Gothic Tarot of Vampires - love it because I'm a fan of the
Vampire the Masquerade Bloodlines (game) and the
World of Darkness (setting).
Harmonious Tarot - Walter Crane's pictures are great. I've found all the books used for the deck and now understand it even better. Every card has its own story which is naturally complemented by Waite-Smith's symbolism.
Universal Wirth Tarot - I think I wouldn't buy it if it was not a part of the collection. I had not read Wirth's books before I got the deck and I had no interest in his writings. But the artwork was beautiful thereby I gave the deck a chance. And I wasn't disappointed. By the way I'd like to thank
kenji for MANUEL SYNTHÉTIQUE & PRATIQUE DU TAROT by EUDES PICARD (
http://www.tarotforum.net/showthread.php?t=60038). Without that book, reading with the deck is quite difficult.
Shaman Tarot - again, I'm not interested in shamanism and wouldn't buy the deck voluntarily. But I got it and started to explore. I'm still not interested in shamanic practices but the deck by itself is amazing.
So the lesson I've learned is to not skip decks in a catalog just because its theme is not interesting to me.
