i was progressing in the fights 6/8 until the shaman hex-lord. in spite of a deck with all battlecry cards and the totem that increased those battlecries and a big health pool, i was still in the fight until Shudderwock was played with the totem out. big yikes lol
if my hunter was getting current cards beyond king crush that were also op and synergized with the hunter deck, it might be a different story.
IDK when this solo adventure was released, but it seems odd those opponents can get the big stuff.
