Temur War Shaman

Xamã de Guerra Temur (Temur War Shaman) (pt)

Creature - Human Shaman | Power/Toughness: 4 / 5 (CMC 6)
When Temur War Shaman enters the battlefield, manifest the top card of your library. (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.)
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.
