Hi, this is my take on the new expansion shaman, which I think have a existential crisis due the multi-synergies and try-to-be DH.

The combo in this deck has nothing to do with those, in fact I think I didn't add a single class-related card from Darkmoon Faire. Anyway, lets get to the point.

The core of the combo is the double battlecry of C'Thun, the Shattered by using hero power after Corrupt the Waters gets discount by Tour Guide

Of course the main problem is to draw the pieces, knowing that  C'Thun becomes 4 different cards before reshuffling itself its normally a game of chance. Truly enough rogue has its own way, but so do we thanks to this pieces being spells.. So we run 2 copies of Storm Chaser along a package of murlocs that draws for everyone: Coldlight Oracle and Prize Vendor and why not?, since we run this ones we can round it up with Sludge Slurper (to complete the quest easier) and tutor the with the spell Ice Fishing... To finish with the card draw 2xManafeeder Panthara feels nice to me... 1 draw before ending quest, 2 if achieved.

With your anti-aggro kit + Groundskeeper (which the pieces will keep active) there should be no problem to get up to the promise turn

By the way, there is 4 cards that I'm particularly reticent about... [Hearthstone Card (Gluttonous Ozze) Not Found] is my tech vs weaponry, which is nice if you ever need it and the 2 copies of Bilefin Tidehunter is a choice that I made to fill space... But the last one it's a test that I need to answer. If work great it can be a big blown out for hero power dependent decks, if not... feel free to substitute it for whatever.

The card is Grizzled Wizard and I and to know if you exchange hero power before quest and then complete it, what will happen? If you checked the interaction and know by fact the answer, please leave a comment. In fact any comment about developing the deck will be welcomed.

Have a great day everyone!

PD: After some research, seems the wizard would be detrimental so I decided to I have subtitute it and the bilefins with two Hot Spring Guardian and a Witch's Apprentice

PD2: I have seen the corruption version on the deck, and i got interested in the use of  Lightning Bloom, so for now I'll take the Apprentice out for a copy

PD3: After a few matches, the first  Ice Fishing bu the second one normally blanks, so i change it for a bloom
