Hearthpwn

This deck took me to legend this month and I think it is really good in this meta. It is able to do well against quest warrior and miracle rogue, which are the two main decks on high rank ladder at the moment.

In the early game you want to curve out and get the elemental battlecry synergies, then in the late game you want to finish your opponent off with face damage mixed with burn damage from the elementals and Jade Lightning

I chose the Fire Plume Phoenix instead of the Tol'vir Stoneshaper because curving from the phoenix into Servant of Kalimos is really good and phoenix is a good card in itself.

I think the jade package is a great fit for elemental shaman. The Jade Claws are an integral part of the early game. It helps keep the opponents board clear so you can have time to fill your own. Jade Lightning is very good for removal and burn. Aya Blackpaw is a huge value machine.

MULLIGAN

Always Keep: Fire Fly and Jade Claws

Vs Aggro: Maelstrom Portal, Tar Creeper, Lightning Storm

Vs Control: Flametongue Totem if you have Fire Fly or Jade Claws, if you already have a good curve I have kept Mana Tide Totem and Servant of Kalimos in my opening hand before.

The most important thing when you choose your mulligan against mid range and control decks is to have a good curve.

If you have any questions about the deck ask them in the comments and I will answer them.
