“Hideaway 5 <em>(When this enchantment enters the battlefield, look at the top five cards of your library, exile one face down, then put the rest on the bottom in a random order.)</em> <br>Whenever you cast a multicolored spell, create a Treasure token. Then you may pay WUBRG. If you do, you may play the exiled card without paying its mana cost.”
