Spectral Shrine

Whenever a creature you control deals combat
damage to an opponent, they discard a card at
random for each shrine you control. If they can't
they lose 2 life for each card not discarded.
Whenever an opponent discards a card, you may
draw a card.
How does one kill fear, I wonder? How do you shoot a specter through the heart, slash off its spectral head,
take it by its spectral throat?
