Rubik's Cube

Every other rainbow noncreature permanent you control has hexproof and indestructible.
When Rubik's Cube enters the battlefield, choose a color. Creatures of the chosen color have your choice of flying, lifelink, deathtouch, or trample.
{w}{u}{b}{r}{g},{t}: Search your deck for a rainbow card, put it into your hand, then shuffle your library. Permanents you control lose hexproof and indestructible until end of turn.
