This was the hardest deck with wich i could defeat the Lich king and also was the last one for me to get Arthas, it tooks me like 50 restarts but is cheap and basically you need to get Alleycat + Scavenging hyena in your hand and try to buff a big hyena trading beasts like alleycat and spells like On the Hunt and Unleash the hounds. Tracking is very good to draw an specefic card like Crackling Razormaw to give Windfury to hyena or Kill command for more damage, and hunter mark helps you to kill water elemental or sludge butcher. I only recommend this deck if you have a few hunter cards like me because its painfull.
