Shuriken of Fate

Secretive - When Shuriken of Fate enters the battlefield, exile up to two cards from your hand face down. (You may look at those cards any time.)
{t}: Shuriken of Fate deals 1 damage to target creature. Then you may reveal a card that was exiled with Shuriken of Fate and put that card into your hand. If that creature's converted mana cost is equal to the revealed card's converted
mana cost, destroy that creature.
