text: During another player’s untap step, effects that would otherwise cause your creatures to stay tapped don’t apply because they apply only during *your* untap step. For example, if you control a Quest for Renewal with four or more quest counters on it and a Deep-Slumber Titan (a creature that says “Deep-Slumber Titan doesn’t untap during your untap step”), you untap Deep-Slumber Titan during each other player’s untap step.
