At Arizona Charlies West I got a couple of cards at the desk, and a couple in a sweep of the casino. Shades of the color variations over at AC East, when i got home and looked the cards over, one most assuredly has a difference. Three are light blue, one is purple-ish. Over at AC East, they have signs up that say the Ultimate card is coming, but when I asked at the booth, the most she could say was "soon." The back of the card mentions both Arizona Charlies and the Stratosphere, so the cards will be going there too. And over at the Stratosphere I picked up one of these black temp cards, with nothing on the back but the magnetic stripe.
