These are all the Hearthstone: Knights of the Frozen Throne cards shown so far by Blizzard Entertainment and youtube/twitch influencers.
Awesome! Ben Brode uploaded a 5-minute video telling the whole story of Arthas as a rap song. It is totally crazy fun to listen to. If there is an Award for this kind of creative work, submit it. It will surely win the nomination for its genius.
Dave Kosak posted a video recently to announce that adventurers who defeat the Lich King in Hearthstone: Knights of the Frozen Throne with all the 9 heroes will automatically unlock a new hero portrait to replace Uther: Prince Arthas.
In addition, Dave Kosak also revealed new cards: Bolvar, Fireblood, Light’s Sorrow, and Corpsetaker.
