Also, isn't Skulking Geist necessary to counter Jade druid ?

-1 Loot Hoarder if you feel like you are facing a lot of jade druid

Agree

I feel like there are way to many death rattle minions to play dirty rat.  How about that new 4 mana 2/3 taunt that drops an extra 2/3 taunt?

What about Elise the Trailblazer to get value from Dead Man's Hand ?

Good idea but I have no idea what to replace though. Perhaps -1 shield block?

Elise is really unnecessary with the c'thun win condition I think.

You really need card draw in this deck to draw your win condition cards asap(Dead Man's Hand and C'Thun) and you also need hp. And Shield Block solves both problems. Elise the Trailblazer, on the other hand, is really bad in this deck (it can be good if the meta becomes really control decks heavy), because you don't really want an Un'Goro Pack in your deck. Why? The same reason: you need to draw your win condition cards asap.

So i agree with zac675 and disagree with Raemo. There is already enough value in Dead Man's Hand + C'Thun combo.

1. You only have 2 copies of C'Thun's Chosen and 2 copies of Doomcaller to activate Ancient Shieldbearer's and Twin Emperor Vek'lor's battlecries that is absolutely inconsistent, unreliable and incredibly slow. You can easily find yourself in a situation where you are not able to use Ancient Shieldbearer + Shield Slam combo or you are simply getting rekt by aggro. Moreover, your C'Thun won't be big enough to end the game with such lack of buffs. So you need more C'thun cards.
2. Why do you need 2 copies of Doomcaller alongside with 2 copies of Dead Man's Hand? Dead Man's Hand is basically a 2 mana Doomcaller with a small difference: C'Thun actually has to be in your hand to cast it. In how many games would you need to play more than 2, ok, 3 C'Thuns (cause your C'thuns are not gonna be big due to the lack of buffs as it was mentioned earlier)? Again, incredibly slow and inconsistent. So you need more C'thun cards.
3. To stall the game to the point where you will be able to play multiple C'Thuns you have to have more removals and card draw.

Based on all of the above i would've suggested some changes:

P.S. And, btw, isn't Quest Warrior just better?

Thank you for the constructive criticism I will make sure to make changes to the deck

Ohhh I never even thought of the synergy of the cthun combo with Dead Man's Hand, I hope it works!

that seems nice, but no twin emperor?

I was thinking of replacing it with the warrior dk when it comes out if it is good enough. We will see though
