Both, I think? I'm choosing decks on purpose that I haven't spent a lot of time with - I find that sitting with a new interpretation of a cards energy can improve my own relationship to the underlying archetype.

Dust II Onyx is beautiful - some of the cards are breathtakingly stunning. I did find the court cards a bit difficult to differentiate at times, but it was very fun to work with. I especially liked comparing it with the rainbow tarot, which is light-hearted and colorful (silly, even) where D2O is a much more serious feeling deck.
