Hunter is a class which excels in the early to midgame but eventually runs out of steam after some turns, hunter class lacks decent card draw so eventually come late game you draw your low cost cards which can’t benefit you much in that stage of game.
So I thought of adding Hemet, Jungle Hunter to the deck so all upcoming draws would be of greater value this too increases your likelihood to draw some more win conditions from your deck such as The Lich King which gives you Death Knight cards to win your game. Lastly, I love how Deathstalker Rexxar could create some amazing plays and if you are good (or lucky) with creating your zombeast then it could help you wreck your opponents too.

• Alleycat: Great beast to start off a match. Good for activating cards such as Kill Command or even Nesting Roc and of course if you have nothing else to buff using Houndmaster or Bonemare. This also serves as two pieces of food for the Starving Hyena.
• Crackling Razormaw: This card can make wonders, it can buff most of the cards in the deck. Remember to choose wisely.
• Kindly Grandmother: This card has great value being a 2 mana 4/3 take note that this is a beast and can be comboed with Tundra Rhino to deal its full 4 damage on an enemy.
• Scavenging Hyena: This card can easily become out of hand if your opponent lacks the removal for it. Best comboed with Unleash the Hounds where it could get much food.
• Animal Companion: This card is a bit RNG-based but still good if you get a good roll on what you need. Remember, Leokk can be useful too (Unleash the Hounds could make many 2/1s).
• Eaglehorn Bow: This is a removal that will mostly help you get board control, if you don't have it.
• Kill Command: One of the few spells I added in the deck, serves 5 damage most of the time.
• Unleash the Hounds: Great spell overall. Could create game changing plays and comboes well with other cards in the deck.
• Houndmaster: This card has a very high value specially in this deck where it can buff almost all of the cards included.
• Dispatch Kodo: This card was suggested in the comments and it actually works wonderfully well with the deck and helps in getting the board.
• Infested Wolf: This card is something like a middle point of Haunted Creeper (R.I.P.) and Savannah Highmane. A really good card.
• Tundra Rhino: This card can be good at times but don't rely on it too much cause it will get removed most of the time. 
• Deathstalker Rexxar: ZOMBEASTS FTW! You just need to learn how the cost of the beast will be and which effects work good together and you're good to go. Remember that the time this is played you get an Explosive Trap explosion and can help you clear the board.
• Savannah Highmane: Probably one of the best rare cards in the game, it provides so much value. 
• Call of the Wild: Provides you with a 5/2 Charge minion, a 5/4 Taunt minion, and a 2/4 minion that buffs your other minions. Good for either finishing the game or for stalling a bit more.

• Hungry Crab: I put this card in for those pesky murlocadins. You can easily sub a Golakka Crawler if you see a lot of pirates. If you don't see much of those paladins or warriors you can swap a Fiery Bat in this slot.
• Nesting Roc: With the deck's ability to produce multiple minions, it is easy to make this a 4/7 taunt minion.
• Hemet, Jungle Hunter: This card makes it possible to survive top-decking phase, makes your next draws worthwhile. 
• Bonemare: I am actually surprised at how much impact this card can give to the board. This is just so good not to put in a deck.
• The Lich King: DEATH KNIGHT CARDS ARE SOOOO GOOD! This is just like an Ysera on drugs.
• N'Zoth, the Corruptor: This card can provide you that finishing blow come late game.
