Reno Midrange Shaman

All I can say about this deck is that even though I'm a mediocre hearthstone player, this deck got me from rank 16 (where im normally at) to rank 8 (highest I've ever been).

Mulligans:

Against warlock, hunter, or Paladin keep lightning storm, elemental destruction, healing wave, cult apothecary, and Reno Jackson

more on this at the bottom

Tips/combos:

Doomhammer + Rockbiter weapon is an amazing combo for lethal and with all the healing in this deck you can hit minions more often than normal

Hallazeal the Ascended + lightning storm or elemental destruction (+azure drake or hero power for damage) is one of the most powerful board clears and healing in the game

Zealous Initiate, Anubisath Sentinel, Primal Fusion, Mukla's bananas, flametounge totem, and Rockbiter weapon can all buff Al'Akir the Windlord for extra damage, so never forget to set those all up T9 or sooner to buff Al'Akir

Master of evolution and evolve work best with the following minions:

jeweled scarab , tuskarr totemic, azure drake, cult apothecary, fire elemental, at times al'akir

and shoudn't be on these minions (unless you're thinking or a really situational one):

zealous initiate, flametounge totem, totem golem, flamewreathed faceless
