Hey there ! I guess you are looking for a viable shaman deck ? So this one is for you !!

Its really hard to make a good shaman deck, lets say its almost impossible. I've put a lot of work into this one so i hope it helps out .

Now lets talk about card that can be changed and some that can be replaced.

Earth Shock , Lightning Bolt , Lightning Storm and Feral Spirit are must need. Which means 560 dust in total.

Hex , Flametongue Totem , Fire Elemental and Rockbiter Weapon are the basic shaman cards from  level 10.

Moving forward to Bloodmage Thalnos - I was really lucky to get this one but its easily replaced with Kobold Geomancer
Haunted Creeper can be replaced with Harvest Golem

Lava Burst can be changed with The Mistcaller or Al'Akir the Windlord . I highly suggest to pick either one of these 2 legendary cards instead of Lava Burst

Tuskarr Totemic - one of the new cards this season, really strong shaman card due to the chance of summoning Totem Golem , Mana Tide Totem , Flametongue Totem and any other. Can be changed with Unbound Elemental
Defender of Argus really nice helpful card that saved me countless times. You might replace it with Sunfury Protector , but it wont be the same.

Doomhammer What can i say.. Simply awesome and great combined with Rockbiter Weapon . Probably the best choice of replacing this one is Charged Hammer , or either Bloodlust . Note that Bloodlust wont be that effective.

Azure Drake . Might be replaced with Gnomish Inventor , but again.. it wont be that effective without the spell damage.  You can also go for Argent Commander ,

Piloted Shredder strong mid game card that can be replaced with Sludge Belcher
Crackle - 40 dust craft can be changed with Ancestral Knowledge
********************* COMBOS ******************************
You can rely on combos and high lethal damage with this deck. It has huge sustain and its good for trading or even going full face.

Defender of Argus goes well with Piloted Shredder , Haunted Creeper or Harvest Golem (depends on your pick).

Lava Burst , Lightning Bolt and Crackle can be really deadly combined with: Wrath of Air Totem , Azure Drake or Bloodmage Thalnos / Kobold Geomancer

Doomhammer goes really well (as i mentioned it earlier) with Rockbiter Weapon

******************************
I tried to cover almost everything.
There are lots of legendary cards that can be used for example Dr. Boom.

I hope you enjoy this deck as much as i do. I wish best of luck!

P.S Sorry for my english. + I will accept both positive and negative comments, so be sure to leave one :D .
