DMC Alphas Deck color?
The back of the DMC Alphas deck looks like a different color from the other decks with the "optical marking system." If so, that's crazy, because you would want to be able to use one regular deck for other tricks and then switch in the Alpha deck for a reveal. (For example do some tricks with a conventional deck, deck switch, force some cards and then reveal that the cards they "chose" spell their name). Are they different colors?
