Update 1.3: Replaced one Mana Tide Totem with one Primordial Drake to better contest aggro, plus I've found there is still enough card draw. Sometimes Mana Tide Totem can even draw too many cards.

Update 1.2: After playtesting, I have deemed Hagatha the Witch a poor fit for this deck, both because the Hero Battlecry can kill your Shudderwocks and because the passive hero power constantly fills up your had whenever you try to set up the deck's combo. Furthermore, I have found Brrrloc to be a more flexible freezing tool than the Voodoo Hexxer I used previously.

With 9 cards that draw cards and choice stall cards like Healing Rain and Voodoo Hexxer, the deck can more reliably find its combo pieces and survive until turn 10. The main idea is to have a cost reduction on Murmuring Elemental to combo with Shudderwock in order to guarantee you a discounted copy of Shudderwock returned to your hand. The deck can do this in three ways:

1.) Play Fire Plume Harbinger while at least one Murmuring Elemental is in your hand.

2.) With 8 mana, play a Murmuring Elemental into Grumble, Worldshaker.

3.) Getting lucky and have a Far Sight hit either a Murmuring Elemental or Shudderwock itself.

From there, you just need to make sure Lifedriker, at least one Saronite Chain Gang, and Grumble, Worldshaker have all been played prior. Then you play Murmuring Elemental into Shudderwock to gain a Shudderwock in hand, then the next turn play 10 Shudderwocks that all deal 3 damage (Total of 30).

I'm only including one copy of Fire Plume Harbinger in order to let Sandbinder draw missing combo pieces more consistently. This is also why Tar Creeper has been omitted from the deck list.
