This deck steam rolled through all but one opponent at 11 wins, just didn't have a good start. The steam roll began after getting Dragon Blood for +1/+1 to your minions after a dragon dies. Then picking up emerald goggles. (Left most card costs 2 less but not less than 1). 

This deck essentially goes all in on getting one or both of the (good) dragon treasure's. I never choose the dormant dragon treasure, it's just so slow. 

If you can get Onyxia Broodmother on the board and not be killed outright, you essentially win unless they can kill all your minions at once. There are 2 board clear treasures that can do this. So pick up another Broodmother if you can or pick her from Draconic Studies. (discover a dragon, your next one costs 1 less). 

Always take Dragon buckets or restore/control buckets. Take "no more, please" over a bucket that doesn't fit with either of these, always. 

DISCAIMER: I didn't use shadowform, I used both shadow words, for control. Still can't add SW: Pain for some reason.
