I'm surprised I'm actually interested in playing this one. Due for August, with 135 new cards in the set. What actually is a cool concept I hope they run with is rather than having added a new Deathknight class (which may have been better but this is just fine) they are releasing Death Knight versions of all the heroes that have new hero abilities. This is done through a new card type "Hero Cards" which change your hero, give them armor and or weapons. Deathrattle is back in full force and Lifesteal is a new keyword. Raid is going to be a 3 tier and boss battle Icecrown Citadel. Nice seeing something more serious after the last few expansions.

The Art in this trailer is lovely.

Speaking as someone who has no understanding whatsoever of TCG, what makes this one interesting...and what the hell is Deathrattle?

Battlecry is an ability that gets activated only once, once you summon a creature. Deathrattle is the opposite. It gets activated once a creature dies.

Lifesteal will benefit Warlock and Warrior more than the others.

Lord Marrowgar is boning me hard.

Beat the First Wing.

Marrowgar was a bit close, but I managed to do it with a secret Mage Deck.
Saurfang was much harder, since I used a Ultra Budget Warrior Deck with lots of Taunts. (Note: Really save your Weapons for Face.)

Deathwhisper was really easy.

Finally took down Marrowgar with a steal your stuff priest.

Took Saurfang on the first try with a Weapons and Taunt Warrior

Death whisper went down on my second try with a shaman Murloc Deck.

Just beat Wing 2.

Two Words:

C'Thun Priest.

Works absolut godly against this wing, specially Putricide and Sindragosa.

(I was very lucky against Lanathel. I quickly beefed up Northshire Cleric with the Vampire HP and Power Word Shield and managed to put up a good board.

And then she turned one of my servants in my hand into Evolve.....

One word: Warrior. Wing 1 and 2 with first try
