Yeah, the gold cards look horrible now.
I miss the way on green cards it looked like there was wood in the text box.
Actually all the colors, plus artifacts, had a unique background. Blue and red were the most boring. Artifacts had tile and white had a sort of stucco look and black had an ancient parchment.
One thing I really liked about the ancient cardface was how the lands would change from set to set. In Ice Age/Alliances they had a purplish look, in Homelands blue, in other sets varieties of gray and tan and brown.
