Knights of the Frozen Throne is an all new expansion coming to Hearthstone in August. It features a new card type that changes all the in game heroes to Death Knights that are themed to the class. The announcement video shows off Deathstalker Rexxar which has a battlecry that attacks all enemy minions for 2 and changes his hero power to create a Zombie Minion. Knights of the Frozen throne also look to bring back Deathrattles, a card type that we saw a bit less of after the last set rotation. This expansion is also the first to include an all new single player component that costs no gold or money to play.

"The first steps you’ll take to join the Knights of the Frozen Throne will be within Icecrown Citadel. There you’ll be faced with eight Missions – new single-player content for Hearthstone. Beginning with the Prologue, and then proceeding through grueling battles with Icecrown Citadel’s mightiest denizens, your trial will culminate in a showdown with the Lich King!

Though you risk your soul merely by entering Icecrown Citadel, the Missions will cost you nothing! The rewards for braving them, however, are enticing indeed: after completing all the Missions, you’ll receive a total of three Knights of the Frozen Throne card packs. Completing the Prologue mission will also add a random Legendary Death Knight Hero card to your collection!"

What do you think of Knights of the Frozen Throne? Does this expansion look like something you will play when it comes out in August?
