Just go face. 

Trade only if you have to. 

Keep 1 drops. 

Dire Mole into Crackling Razormaw is your best opening.  

Best Matchups - 

Almost everything 

Worst Matchups -  

AOE or fast decks like Odd Paladin or Warlock. 

Even Warlock.

I'm Currently Rank 4 with this deck and struggle against Odd Mage mostly.  I can't wait until Odd Mage rotates out.  

I'm not sure what the best target is for Dire Frenzy but I always try and hit the 1 drops.  

If you can draw them with Master's Call it can be a good swing turn.  

Try not to flood the board if you know it's an AOE or Scream turn.  

Bearshark is one of my favorite cards in this deck.
