While there are some great looking card backs, over all they are just overrated.
Reason is that our opponent has the best view of our glorious and perhaps hard to attain card backs.
All we get is the image at the side of the board.
Just an observation but really it is true, our opponents see more of our card backs than we do.
I'd like to see more very hard to attain card backs because with these it would be about prestige. Does not matter how it would look, ugly is even good as
our opponent has to look at it more than we do. Card backs purely for great art, waste of time.
