• Also, since this card can treat "Crystal Beast" monsters on the field or in the Graveyard as DARK monsters, this card is especially helpful in summoning "Rainbow Dark Dragon".
  • This card allows you to utilize DARK monster support in "Crystal Beast" decks, including "Dark Armed Dragon".
  • You can also include "Malefic Rainbow Dragon" in a Deck that uses this card (since it is a Field Spell Card), but beware: this monster is not able to utilize this card's negation effect.
  • This card makes it easier to fulfill the requirements for "Rainbow Gravity". Furthermore, "Rainbow Dark Dragon" will be easier to choose for that card's effect as well as for "Rainbow Path".
