Okay, so I owe dawn a Heimlich maneuver and shiro a fresh pair of pants? Is that my total score for today?
I'd say I fall somewhere between dawn and hsbc, though perhaps closer to the former. I've bought just a couple oracle decks, when I found the artwork particularly compelling in some way, but in most cases I've stuck deliberately to decks based on the RWS system, and always to decks that are fully illustrated (i.e., no "pip decks," or decks where the numbered cards of the minor arcana show only pips without further illustration). In the handful of times I've attempted reading I leaned heavily on the guidebook, and using a RWS-based deck opens up entire libraries of reference materials you can use to get a better handle on the meanings of each card. With oracle decks you're unfortunately entirely reliant on the guidebook provided by the creator, and in many cases these are... less than clarifying. (This was actually my complaint with UUSI's Supra Oracle deck, and the reason my vote for the 2018 Non-Poker DotY went elsewhere.)
I don't really use my tarot decks for meditative or introspective purposes, but as dawn said, "I think my purchases should be usable in case I ever want to use them." Keeping the symbolism as broad as possible - that is,
not designing a deck that's tailored only to a single specific topic of inquiry - is, to me, an important part of that utility. In a sense I think of a good tarot deck like a nice set of china: I'm not going to pull it out and use it more than once or twice, but if the mood strikes I want the deck to be functional and suitable for what I have in mind. (In this metaphor, an erotic tarot like this one would be akin to
the Grecian bowls from The Birdcage - amusing for sure, but not appropriate for all occasions.
