Hi Everyone, 

I share with you my first deck here on this site. Its an Elemental Shaman that can find all the answers and has potential to win against most common decks currently. 

Usually you have enough removals against aggro decks, but also lots of late power and value to sustain against control decks. 
Don't worry to take some damage early game, you have big heal potentials.

The Mountain Giants are mainly there to drop a big threat early and to force your opponent to invest some resources. If you can hit face one time, that's always a plus of course. 

At Mulligan, Menacing Nimbus is a keeper against almost every deck. If you are on the coin and hold Earthen Might I usually coin him on turn 1 (except against Rogue and Hunter - since they might fear you are a murloc shaman and therefore keep/mulligan for early removals like Backstab or Bomb Toss

More details and guide, if there is some interest in this deck. 

Enjoy!
