Diligent Mercenary

Belief {2} (You may cast this card without paying its mana cost. If you do, each other player may pay {2}. If no mana is paid this way, counter this spell.)
First strike, vigilance
When Diligent Mercenary enters the battlefield, if it was cast for its belief cost, target player that paid gains control of it.
He'll take your money, and work elsewhere.
