Temur War Shaman

“When Temur War Shaman enters the battlefield, manifest the top card of your library. <em>(Put that card onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)</em> <br> Whenever a permanent you control is turned face up, if it's a creature, you may have it fight target creature you don't control.”
