At the beginning of your end step, if you gained
5 or more life this turn each opponent may
sacrifice a nonland, nontoken permanent or
discard a card, each opponent who doesn't exiles
the top card of their library face-down. You may
look at and play the cards exiled this way and
may spend mana of any color to cast them.
