I'm a bit disappointed. Why Shaman? Why this weapon? It doesn't fit in any current Shaman deck. So does this card alone create a new Shamn archetype? No I don't think so. I could this being awesome IF it were a neutral weapon, but alas no.
4 legendaries and all of them feel weaker than the the worst DoD legendary (maybe with the exception of Reno). This adventure is beginning to feel like DoD leftovers; like they had a lot of left over ideas and decided to make some money on cards that didn't make the final cut. Yum leftover ideas... my favorite. The rest of the cards have to blow my socks off for me to change my mind.
The previous adventure's Legendaries were so innovative and widely usable. So far, these Legendary cards are made for one specific kind of deck, and now, only for one class's one specific archetype. It's not even that mindblowing or creative.
I don't know if they're going to produce more Legendaries to this set than the usual, but either way, I'm tired of Legendary cards that create more Legendary cards. It might be exciting for new players, but we get a card with this effect in every expansion.
