[Hearthstone] Knights of the Frozen Throne the Arena Perspective Part 1

So its finally time for new Hearthstone cards. This time each class is getting a new class hero power from 1 unique legendary card per class making them "undead" death knights. What we have so far is death knight Rexxar and his power is really, really good for arena. Its an infinitive card machine so looks sick, the other cards I dont think will have any impact at all.
