Advanced Dark is the only card they need, it makes them all dark by itself and the advance versions are exactly the same as the regulars, just different artwork. Even with Advanced Dark I wouldn't run the Rainbow Dark Dragon though, too slim a chance to have him and Advanced Dark. Although Advanced Dark would be amazing, mills the deck and no damage, win/win for CBs.
1. You don't HAVE to run Rainbow Dark.
2. Have you seen how much support DARK monsters have?
1. I said that I would not run Rainbow Dark
2. We're talking about CB's, not DARK monster support
