Hmmm... I can't tell which version I like better... but I think possibly the new "UC" logo version...
Only two things I can say about "UC" logo option at the moment:
1. Seems like the logo in the middle is kinda... too large.... or something. Too prominent for just two plain letters. Maybe if the letters had more detail to them like some kind of tarnished metal look, then it would be fine.
2. Might be interesting to consider how it would look if the logo were not "on top" of the diagonal bar. Perhaps it could be somehow enveloped by the diagonal bar. (I'm not too sure about this suggestion.... just a thought.)
The king court cards look pretty cool.
1. What if the kings had green eyes??
2. I like the king of clubs & spades much better than the hearts and diamonds. The clubs/spades have green TRIM on their clothes which looks nice... but the hearts/diamonds have too much green FILL on their clothes.
Concerning the border on the back design.
1. I really like the green color of the border.
2. I am a little afraid that with standard fat white borders, plus the green border, plus the silver metallic border... that it might be too much border. But if we do end up with skinny white borders, then it would probably be fine.
