I've spent by far the most time on trying to make this combo work because I am a clumsy ditz who needs lifesteal to change my diapers. This deck is pretty self explanatory for a Fire/Primal combo; hit hard, hit fast, hit as much in as many ways as possible.
There's still an element of control with the cheap draw, negate, and stun cards, but they also help maintain your offensive onslaught by protecting your units and delaying the opponent's next move for as long as possible.
This deck's main function is to provide you with variety in your offense. Want to charge your Passionate Stonehammer with a Gemblazer Cannon? Or the same move with the Brand, Without Fear, courtesy of the Jawbone Greatsword that also happens to be an overwhelm weapon? Want to simply charge your units with The Throne Room? This is a fun deck to experiment with, and I hope you have fun with it.
