Forceful Acquisition

At the beginning of your upkeep, target opponent reveals his or her hand. Choose a nonland card from it. Until the end of turn, you may cast that card as long as its converted mana cost is less than or equal to the number of pirates you control. You may spend mana as though it were mana of any type to cast that spell.
Pirates will take anything at any cost, no matter how high the cost is.
