I have had this deck for about a week and I love love love it! I like this deck so much that I've been carrying it with me in my purse to work. I don't use it there, but I like knowing that I have it! It feels very magical--possibly because of the constellations printed onto the cards. As for the art, there are many cards that stand out for their beauty--just SOME of my favorites are 1 of Air (Microscopium), Black Hole, Page of Water (Columba), Worm Hole, 10 of Air (Perseus), 10 of Earth (Circinus+Crux) and The Lovers (Cancer). There are a few cards that I don't LOVE, they are The Tower (Eridanus), The Star (Gemini) and, you guessed it, Temperance (Pictor). They don't bug me enough to not love this deck, though. I had no issues with the cutting or quality of the deck as well.
I think this deck works best if you think of it as a tarot-oracle hybrid. There are certainly quite a few cards that don't obviously align with their RWS/Thoth meanings. That's to be expected if you're trying to fit an existing framework (like constellations) onto the tarot structure. If this would bother you, I highly recommend that you just approach this deck as a large oracle deck. There are many things to pull meaning from on the cards--the artwork, the mythology of the constellation, the book meaning, etc, beyond the standard tarot card meanings.
There is ONE complaint I have about this deck: the book. There are quite a few typos, unfortunately. Also, there's one big error that I noticed while reading it. The description for the Queen of Fire (Cassiopeia) is the SAME as the description for The Devil (Andromeda)! It's SUPPOSED to be for The Devil, but it looks like someone just accidentally copy-and-pasted the wrong description. I've considered emailing them about this, as it bugs me quite a bit! Nobody has mentioned it before in this thread, so is it maybe just an issue with my copy?
