Sightless Watchers

When Sightless Watchers enters the battlefield,
each opponent reveals their hand. Choose any
number of noncreature, nonland cards from
among them and exile them. You lose life equal
to their converted mana cost and discard a card
for each card you exiled this way.
Whenever you discard a card, gain 3 life.
"I eat undead for breakfast but this...thing...it scares
me."- Bavori, Shawz Fiend Hunter
