Azindel, Revealed

When Azindel, Revealed enters the battlefield,
create two 1/1 black Assassin creature tokens
with unblockable and deathtouch.
Whenever a creature you control deals combat
damage to a player, exile the top card of that
player's library. For as long as that card remains
exiled, you may play it by spending its mana
value minus two. (For example, {1}{w}{r}{g} becomes {2}.)
