I pulled my Thoth out to look through it to see which cards I dislike so much and there were surprisingly few. And some cards I like a lot, such as the Chariot. In fact, the Two of Disks I like enough that I'd hang it on my wall if I had a poster of it.
Cards that turned me off to the deck (and possibly the reason for my bad first impression of it): The Fool, The Magus and the Priestess. I can't deal with the pig snout on the Fool, The Magus looks like Miss America throwing candy and waving to children during a parade, and while there isn't anything particularly bad about the Priestess, she just isn't my favorite interpretation of that card. I think those three right in a row and the first cards in the deck gave me a bad impression overall.
Several cards are very nice, but there are three others that I also think are ugly, and they are also, oddly, three cards in a row: The Knight, Queen and Prince of Swords. I'd like the Queen of Swords, actually, if her shoulder wasn't dislocated.
Anyway, it's a quality deck, and like I said, it grows on you. I thought it was the ugliest deck ever created for several years and now I can only point to six cards that I don't like, and of them only four really bother me. In another year, I probably won't remember why I ever disliked it.
