There are no specific dragons to use, you have a small chance of getting a Rainbow dragon whenever you breed a combo with 4 or more different elements. Popular combos are the ones with no chance of Sun/Moon and a low average breeding/incubation time if you fail like: Brass + Cactus or Seaweed + Firefly, they don't have a better chance but they do allow you to make more tries for less time/gems. Good luck.
