First attempt at making a Beast Druid for Deck Doctor Challenge #7.  Join us over in the thread to discuss this archetype and share your own creations!

This deck prefers control matches so you can mulligan hard for Predatory Instincts in the hopes of dropping it on Turn 4 followed by a buffed Witchwood Grizzly on T5 or, ideally, Stampeding Roar into a buffed Ironhide Direhorn on T6.  You can then drop Witching Hour if they kill off your buffed beast and starting on T8 you can combo this with Faceless Manipulator in the hopes of hitting a buffed or high health beast with Crazed Alchemist for some finishing damage.

In aggro match-ups you mulligan primarily for Doomsayer and Wild Pyromancer, but may also keep things like Wrath and Keeper Stalladris.

Survivability and card draw is achieved via Pyromancer + Acolyte of Pain against aggro and Ferocious Howl against control.

Crystal Power acts as a cheap Pyromancer activator against aggro and a way to heal your buffed beasts against control (will typically save Stalladris to combo with Crystal Power against control for more healing).

Moonfire has similar synergy with Pyromancer and can be used to take down a giant if you're able to pull Ironhide Direhorn with Stampeding Roar.
