Deviant Moon is definitely my favorite deck. It was the second deck I ever bought... my first, I bought on more or less a whim, knowing nothing about tarot cards, and it was fine, but not really "my style" (it was Tarot of Mermaids). After having used that deck for a while, I went searching online for a deck that fit me better, and had trouble finding something that really stuck out to me. Then one day I stumbled across a picture of the Hermit card from Deviant Moon, and I was like "That one!" I couldn't believe I had found something so perfect! Truth be told, I enjoy a little bit of eerie, and I think part of the purpose of tarot is to push you out of your comfort zone a little. Deviant Moon really isn't that dark, but it has just the right amount of atmosphere, in my opinion. And just the right amount of surrealism. Not so much that the images are confusing, just enough to make them a little foreign.
