A Great Unenchantment

Players skip their combat step unless they tap
three creatures, or exile one creature with the greatest power among creatures they control.
Creatures tapped with this effect do not untap
during their controller's next untap step.
"'But here,' said the girl, 'it is different. Here he
cannot kiss the Princess till he has dissolved the
enchantment.'" The Voyage of the Dawn Treader, 13.
