Capricious Apocalypse

For each non-goat permanent your opponents control, it's controller may put a 0/1 white Goat token onto the battlefield.
If they do not, destroy that permanent and it's controller is dealt 1 damage and you gain 1 life.
"Those weren't meteors raining down from the heavens, they were goats. Millions of goats. I can hardly recognize the place now."
