Stonescar Midrange

I've been seeing a lot of different Stonescar build today and I wanted to try a more version that plays more midrange and has some late game punch (Dizo's Office and Big Vara). I've had good success so far with the deck at Masters. I'm really liking Flame Blast as a removal or finisher. Dealing that last 5-8 pts of damage towards the end of the game is amazing and you have the Vara's Favor, Highwayman and Baby Vara to deal with Face Aegis. Azindel's Gift in the market is to deal with control decks. The only thing I'm not liking so far is the constant topdecking and small hand size towards the late game. 4x Quarry and Dizo's Office is good to refill but not enough. Would love to hear your thoughts on how to make this deck better, having a blast so far!

Edit: Big Vara was moved to the market. In comes Xo for card draw and market fodder. Dark Return and Auric package for more card draw and bringing back threats. Flame Blast is a great finisher or removal, has been MVP so far. Deck is performing well at Masters so far.
