Hostage Taker [Outlaws of Thunder Junction Commander]

When Hostage Taker enters the battlefield, exile target creature or artifact until Hostage Taker leaves the battlefield. You may cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any type to cast that spell. Umbar was a refuge for all the enemies of Gondor a threat to its coastlands and to all traffic on the sea.
