Arthax, King Of Dreams

Flying, hexproof, vigilance
Cards exiled by your opponent's must be exiled
face up.
Whenever a spell or ability targeting you would
cause you to reveal your hand, you may reveal it
with the cards face down. It must target a card
for it's effect while the hand remains face down.
If the card can't be the target of the effect,
counter it then draw a card.
