[jett93]

can i use jirachis power of stardust song to attach rainbow energies to istself from the discard pile?

When I read the Rainbow Energy card, it says it counts as :colorless: when not in play (it is not in play, when in the discard pile), but Jirachi can only get sychic: out of the discard pile.
