Nezabog, the De-Knower

Nezabog can't be countered.
Players can play cards they own exiled with
Nezabog, the De-Knower and can't play cards
from their hand.
If damage would be dealt to a player, instead exile
that many cards from the top of that player's
library. Players don't lose the game when their
life total is reduced to 0.
