Hearthpwn

NOTE: This is not a 100% WR deck. You can still lose if you draw like shit. I tested this deck a few times and I'd say it's a 80% WR deck.

Shaman is the best class if you want to beat this boss using a control deck. This is for two reasons:

1. Shaman has a lot of early board clears thanks to overload.
2. Shaman has a lot of transform cards to counter Dawnshatter's hero power (Devolve, etc...).

The deck is simple: remove the stuff she drops and wait for her to die from fatigue (she has Candle Breath x2 and Breath of Dreams x2 while you have no card draw, which means she will go deep into fatigue).

A few precautions though:

1. Keep Hex for her Ysera and Zzeraku if possible. If you can't, it's better to give up on Zzeraku than on Ysera.
2. Do not dump all your poisonous minions at once. She has Crazed Netherwing and quite a few cheap removals. Try to keep 1 on board at all times but not more.

Walking Fountain should be able to keep you alive but watch your HP.

Budget substitutions:

• Plague of Murlocs --> Crushing Hand
• Earth Elemental --> Squallhunter (fight thunder with thunder they say)
• Snowfury Giant --> Eye of the Storm

Alternatively you can just use Mecha'thun Warlock like everyone else.
