Hello,i'll leave a quick explaination:

Clear the Way 4/4 for just 1 mana ,sometimes goes face when summoned with Thundra Rhino

Shimmerfly good valued card

Pack Tactics optimal against Demon Hunter. When facing value decks you can use as a combo card with your big minions, Zixor or Teron

Hunting Party + Scarlet Webweaver those two cards are meant to be used against odd MUs like priest or Highlander decks.  You want to discount Savannah/Thundra Rhino with Scarlet Webweaver ,copy your big beasts and then go face for tons of damage. You can either OTK sometimes with Zixor,Apex Predator

Khartut Defender sometimes it's autowin against aggro MUs also you can combo it with Pack Tactics for a sick amount of healing

This deck can easily beat any kind of meta deck,it has high value , high board control ,good burst of damage.  Opponent doesn't know what the heck you are playing so any plays it's pretty unexpected. 

Mullingan:

Keep any 3 cost or lower card beside Teron Gorefiend
