A very effective Beast Hunter deck that is doing well right now and will do better after the new DH nerfs I believe.  Lots of good synergy in the deck.  Reminds me a little of the Hand-Buff Paladin decks of the past.

Lots of new cards make Beast Hunter a better deck than previous iterations.  Helboar is a great 1 drop that was missing from Beast decks in the past.  Pack Tactics is perfect for maintaining board control and reproducing a good beast.  Scavenger's Ingenuity is a great card and should be kept in the mulligan, as it really has no bad cards to land it's buff onto.  Augmented Porcupine is a stellar card against aggro.  Even though the damage output is random, it does a pretty good job of clearing.  Often times your opponent won't want to attack it because they're afraid of Pack Tactics, so you can force them to using good ol' Houndmaster.

Zixor, Apex Predator Scrap Shot and Burrowing Scorpid round off the new expansion cards.  Zixor is a bit slow but is pretty nice in your slower match-ups.  Scrap Shot is OK, also a bit slow, but it does provide some nice reach as it can hit face.  Scorpid was chosen for it's 2 mana ping over Escaped Manasaber, which I tried but ultimately changed.

The rest of the cards are just good Hunter cards.  One note: Diving Gryphon is particularly good if your Zixor is has died and will draw Zixor's deathrattle buddy Zixor Prime.
