General MulligansDire Mole, Crackling Razormaw, Vicious Scalehide and Cave Hydra are must keeps. Jeweled Macaw doesn't need to be kept if you are against aggro and already have a set curve in hand. Animal Companion and Eaglehorn Bow shouldn't be kept unless you already have a 1 or 2 drop in hand.
This is a midrange hunter deck based on efficient board clearing minions along with Houndmaster Shaw to develop an early board advantage against any deck – yes, even odd paladin – and snowball it to a victory.
Have fun climbing!
