Would adding stormbringer be a good idea

Unless you draw your Fire Fly early, you won't have a big enough board for The Storm Bringer. I suggest substituting the Al'Akir the Windlord /Zilliax/Corpsetaker package for Thunderhead and some overload cards.

I changed the Lich King and Electra for two Far Sight (was think maybe Mana Tide), what you think?

Far Sight could be very interesting, but then you would have to take out both Fire Fly to make it work. Maybe substitute them for Stonehill Defender is the answer?

Gruul is needed in a Shudderwock Deck ... - cut on fungal maybe

Why Gruul? Am I missing something? his ability isn't a battlecry

Should I craft Corridor Creeper ... I had it, and I disenchanted it when it was nerfed.

I would say Corridor Creeper is pretty important in this deck, mainly as a recipient for Unstable Evolution , You may replace it with double Former Champ , though, getting that extra 5/5 body on your board. But it is not as good as Creeper

Substitute for Zentimo? Not sure if it's worth crafting as it seems mediocre but I haven't played it.

Zentimo can be insane in this deck, used defensively with Hex , it turns your 3 of your opponent's minions into frogs (once did it to a taunt druid, instant concede) ; offensively, it can be paired with Unstable Evolution and you get Evolve with echo. Then again, Zentimo is not a must in this deck

I would substitute it with maybe Mind Control Tech ? Due to the spell hunters around right now

Zentimo also good with earthen might zaps and so has alot can do for buffing board and removal

this deck is so much fun!! I was wondering what kind of deck i could build with the new shaman legendarys! Thx!!

Glad to know this deck worked out for you as well!

I feel you man, a Corpsetaker with both windfury and lifesteal can be so intimidating early in the game
