Hearthstone: Knights of the Frozen Throne

De Blizzard Entertainment

An icy wind howls outside the inn's walls, but the chill you feel crawling up your spine has little to do with the bitter cold. No deck is safe from the Lich King's evil influence; even the most stalwart champions of the Light have been turned into wicked Death Knights. As the agents of the undead Scourge plague the land, it falls to you to gather your cards, face these vile abominations, and turn their dark powers against them.
