So this Shaman deck is pretty much set up as a burst Shaman. It has Haunted Creepers as the 2 drop you should mulligan for in order to have early board presence as well as the almost mandatory 3 mana feral spirits. I also run one lightening bolt for early board clear in addition to the Rockbiters. The Sunfury Protector is to weather early aggression by taunting up totems until you can draw Lightening Storm to clear. 

This deck runs deck runs 7 cards with overload which makes Unbound Elemental more valuable as a 3 drop. For additional taunts I run 2 Defenders of Argus to provide a damage soak and extra damage. 

Basically when playing this deck you should be stalling out the early game until you can draw Rockbiters w/Doomhammer combos with Lavaburst's to kill your opponent. Having only one Lightening Storm means you may have to use your Hexes and Lavaburst's on less than optimal targets but remember, Shaman has no heals. 

Stormwind Champion is not the best big minion you could have, but I am staying true to the cards I have and thought it works the best if you don't have any other legendaries to trade it out for. I ran Black Knight for a bit but find that it hardly mattered with the amount of single target clear this deck has. 

Match-ups:

Aggro Decks: Mulligan for your Haunted Creepers and Lightening Bolt. Feral Spirits is very valuable to have as a 3 drop.

Control Decks: Haunted Creeper is still good to have as it is great at clearing and providing annoying early pressure. Against Priest, Lightening Bolt or Rockbiter is good to deal with early Northshire Clerics. Against all control decks you should be aiming to win by dropping your opponent into range of your 15 damage Doomhammer/Rockbiter/Lavaburst combo for lethal. So many classes will heal or stall the game until you cannot win anymore. Don't be afraid to use damage to the face as pressure and know your win conditions.

Mirror: This can be a hard matchup and really depends on the early draws. Feral Spirits is really good and can win the game if your opponent doesn't have Lightening Storm. Combine with a Flame Tongue totem to the face and you can easily set yourself up for the lethal combo.

Hope this deck helps some people figure out what works for them and welcome any feedback.

P.S. Of course some cards are meta situational and can be switched out. I.E I would run two Lightening Storms and one Lavaburst if I could (but I only have one :/ )
