Rastakhan Theorycrafted Midrange Hunter

General Mulligans

Visious Scalehide - Rush is always good for early game removal. Great combo with Razormaw.

Springpaw - Just like stated earlier, rush is good early game.

Dire Mole - Solid stats that contest the board against most aggro.

Crackling Razormaw - A good buff to any rush minions 

Bearshark - Protection from spells and hero power targeting is great against control decks trying to manage the board with spells. Not great against Aggro.

Animal Compaion - Most of the time this is just good tempo.

Scavenging Hyena - A highroll card that wins games a surprising amount of the time against aggro, where you trade in minions to control the board. 

Revenge of the Wild - Great comeback at the end of a Unleash the hounds turn. especially if you had to trade a Scavenging Hyena away. Allows for a full board restore.
