I have been thinking about creating a deck like this after I made a plain deck to experiment with in my own readings I posted this thread
http://www.tarotforum.net/showthread.php?t=237119 to try and get a wider range of keywords than I had came up with myself but unfortunately got no responses.
I was considering having the backgrounds something like space images on the one I was going to create for my own personal use as I like my cards to be visually appealing to me but no actual images and just the word in the centre of the card, lately I've being doing a lot of experimentation with different ways to create a card with different mediums to what stands up to good use, still working on it at the moment not enough time in the day to finish anything though lol.
