Can't say I was happy with my experience against the boss. The first time I had an average deck, but managed to whittle him down to 54 HP.
The second time I had a much stronger deck. But on turn 2 he drew THREE murloc generators, managed to get a [Hearthstone Card (Scargill) Not Found] through the random murloc generation. Which enabled him to get his 10/10 out. Turn 3 he had Everyfin is Awesome and missed lethal by like 8 dmg. Turn 4 I was done for. :(
