Disclaimer: The WR is a very low sample size in a low rank pool, however, if you love DH, I encourage you to not write this deck off. I've tried all the Quest DH variants and this feels the most solid by far. I think this version (which I did not come up with) is dialed in perfectly to be successful on ladder in the current meta.

I absolutely love this deck. The popping off Lion's Frenzy and Brutes is a ton of fun. Kazakusan gives it the much needed gas to close out games, however, most are won by a combination of multiple Irebound Brute copies and a swing turn with Lion's Frenzy.

Here are some tips:

I feel like the correct Turn 1 is to hero power rather than play the Quest unless you Coin out Sigil of Alacrity to set up a Spectral Sight on a Turn 2. Baring that, Turn 1 hero power, Turn Turn 2 play Quest then hero power.

Your Felosophy's are for your Irebound Brutes rather than you Spirit Jailers.

My favorite card draw setup is to have a Tuskpiercer equipped with Persistent Peddler in hand. This gives you 3 cards drawn for 2 mana. 

Knowing when to use Glide is key. I still have a lot to learn about the other classes and how best to mess them up, but obviously the better you know other classes, the more you'll be able to mess with them.

Enjoy!
