This is Dekkster Gaming's take on u/ibbinx's Burn Shaman list. I haven't been playing it long enough to give an in-depth guide (check out the linked reddit post and the embedded video for more of that). What I can tell you is that face is the place. This is a burn deck, after all.

Notable combo:  Doomhammer + Rockbiter Weapon + Rockbiter Weapon = 16 damage in one turn just from your weapon!

u/ibbinx's reddit post has a great guide that includes how to mulligan properly (spoiler: varies from MU to MU, but never keep Lava Burst, Rockbiter Weapon, or Electra Stormsurge).
