Azriel

{bold}Flash, flying{/bold} When Azriel enters the battlefield, look at the top four cards of target opponent’s library. Exile one of them face down, then put the rest on the bottom of that library in a random order. You may look at and cast the exiled card for as long as it remains exiled, and you may spend mana as though it were mana of any color to cast it. Whenever you cast a spell you don’t own, create a Treasure token.
