Sunflower,
My take on the 5 of Physical is that your circumstances are changing, which is based on the four different surfaces in the background. It might even suggest a change in environment, which is again a reference to the background.
I associate hands with work and activity, so when I first saw this card, I got the impression of "having a hand in the situation." Things might be the way they are as a result of something you may have done. If it were to show up in a position in a spread connected to other people, it might refer to someone's actions that create a change in circumstances.
As I work with this deck, I am coming up with associations and interpretations I probably wouldn't come up with otherwise.
As to favorite cards, I like them all so much; in my opinion, there's not a bad card in the bunch (I even like the Death card!). Cards that seem to really speak to me have been Fertility, Disruption, Authority, Solitude, Balance, Shadow, and New Beginnings, all of which are Majors. From the Minors: 5 of Spiritual, 2 of Emotional, 7 of Emotional, and 7 of Mental.
I used the deck to do a reading for someone today (all the readings up to this point have been for myself). She so loved the cards that she told me this was the only deck she wanted me to use when I read for her. I was very pleased with the way they read, and how clear the information had come through. It really is shaping up to become one of my favorite decks--and I've only had it for four days now!
