Hearthpwn

I'm currently running this deck without legendaries (Except Thalnos) but I'm saving up dust for one. Should I eventually craft Fireheart or Bolner? 

I would not play Dunk Tank in the deck with the new card Granite Forgeborn. I tried this and there is some anti-synergy with the cards making the DT's hard to corrupt. 

I agree, luck of the draw. But both of them together are pretty amazing if you can get that synergy.

There's a few early Ele Shaman decks out to incorporate the new expansion, but this is the most logical and easiest to "move up to" from pre-expansion ele shaman deck. 

everytime i see that legendary, i think his name is boinker hammerbeak

I thought at first it was Boner Hammerbeak
