The main problem of their decks is card draw. Other control decks usually draw their win conditions earlier than you do, which makes losing to them feel bad. My deck solves this problem by introducing a beloved mill combo: Murmuring Elemental + Coldlight Oracle.

Against aggro, Murmuring Elemental can be good in combo with Jinyu Waterspeaker as well for massive healing. With so many healing in your deck, you have a lot of flexibility in dealing with the board and saving your AoEs. With that being said, though, aggro is still the worst matchup of this deck, which is the source of its negative win rate in rank 10ish.

Although this deck won't get you very far in winrate, it's a very hard deck to master. You have to plan your future turns, expect opponent's play, and find chance to lay out your mill and giant combos.

Lastly, this really isn't a very refined deck. I struggled between Drakkari Defender and Feral Spirit. Doomsayer, Harrison Jones, the second Lightning Storm, more card draws such as Far Sight,Novice Engineer, Gnomish Inventor, Mana Tide Totem or even Ice Fishing are being considered.

I really hope you guys can try this deck and if possible, offer some feedback to refine this deck.

Enjoy! 

Eventually I gave up the mill combo, since it's definitely underperforming versus aggro, and sometime helps your control opponent draw their win condition.

The new version of the deck went back to use Mana Tide Totem and Thing from Below. Thing from Below usually costs less than Giants because you basically roll a totem each turn before maybe turn 4, and they have lovely Taunt. In combo with Ancestral Spirit, you can stall aggro quite a bit, and in late game, they are great alternative to Snowfury Giant to combo with Greater Sapphire Spellstone.

Another change is to use Earth Elemental. Because we now have less card draw after deleting the mill combo, and we are better against aggro, it's time to add some value to the deck. Earth Elemental is perfect for that purpose. Its 3 mana overload can upgrade your spellstone by itself and if your opponent don't have an answer for it, you can use your spellstone on him next turn, or even better, together with Ancestral Spirit.

Sorry that for realistic reason I have to give up the Murmuring Elemental + Coldlight Oracle combo, which admittedly is a source of fun. But the winrate is getting positive!

Lightning Storm is removed since it's a dead card versus control. Two Jinyu Waterspeakers are removed because their healing usually can't save you if two of your more efficient Healing Rain can't. I've tried Hot Spring Guardian, but gave it up for the same reason. Harrison Jones is also removed but not replaced by other oozes, because I realized a sad truth in deckbuilding: weak decks don't tech. :)

Instead, I put in 4 additional card draws. Loot Hoarders are decent because even priests are using them. I know two Far Sights are the center of controversy. Sometimes they give you surprise, but other times they are 3 mana draw a card, and you would wish Shaman had Arcane Intellect when that happens. I'll test them more and maybe eventually they will get replaced.

This third update actually contains two steps. Instead of using the inconsistent [card]Far Sight[/card], I added two [card]Lightning Bolt[/card] after I lost a game in which I had to use [card]Crushing Hand[/card] on a windfury [card]Crackling Razormaw[/card]. Several similar games made me realize that I need early light removal to deal with small but threatening minions that almost every aggro-midrangey deck has.

Then somehow it occurred to me that Shaman's almighty jade spell package may solve that problem. So I replaced 5 card draws -- two Far Sights, two Loot Hoarders, and the underperforming Bloodmage Thalnos -- with the jade package. Thus, arguably all of shaman's great control tools in standard (well, there are not many) are in the deck, providing answers to nearly all kinds of board threat. Though Aya Blackpaw can't control board, her value makes her just another good target for Ancestral Spirit and Greater Sapphire Spellstone. 

 After several good games with a positive winrate, I feel like the deck is pretty refined right now. Although in this latest version you have less chance to actually play the entire [card]Snowfury Giant[/card] + [card]Ancestral Spirit[/card] + [card]Greater Sapphire Spellstone[/card] combo, some less mighty variants of the combo is usually enough to steal a win, yeah, with Shaman. 

The latest update! With a lot of changes! I have been trying different things to solve the lack of tempo problem that someone raised. The first thing you might notice is the replacement of two Doomsayers with a more aggressive combo: Guild Recruiter and Flamewreathed Faceless. Doomsayer is questionable to some, so in this version I tried to remove it. Also, for consistency to pull out the once infamous 477, I reduced one Mana Tide Totem.

The second is the comeback of two Far Sights. Someone has pointed out that Far Sight into Lesser Sapphire Spellstone or Volcano can really win games. As I tried a few games, it works pretty well, so welcome back! Btw, the art of Far Sight is amazing.

Another change is the removal of two Hexes. A lot of times you would find 4 big removals (Crushing Hand and Hex) too much, especially versus aggro paladins. Although Hex is a better card than Crushing Hand in general, but for the purpose of overloading and upgrading spellstones, Crushing Hand is better performing in this deck. Removing both Hexes, though, is still a bold decision. I will evaluate the decision further. Also, one Healing Rain is removed due to the increased aggressiveness of the deck.

Thanks to @sirzork 's suggestion, I added in two infamous Corridor Creeper to the deck for the tempo they offer. One Far Sight and one Jade Lightning were removed from the list. Far Sight is good when you have nothing to play and 3 mana to spend, but that's about it. Jade Lightning doesn't help with the overload and is sometimes stuck in your hand. I just got a five-game win streak with the new deck list, only losing to a Big Priest. But the rhythm becomes good!

Also, I observed that sometimes on our big turn 5, you struggle between playing Volcano to clear your opponent's board and play Guild Recruiter to establish your own. I almost always ended up playing Guild Recruiter because after Volcano you only have 4 mana next turn which sucks (unless you also have Corridor Creeper). After turn 5, though, you try to compete with your opponent for board presence or even push face damage and force your opponent to exchange your 477. For that purpose, Volcano is usually a dead card. So I replaced one of it with Lightning Storm, which is good when both you and your opponent have board.

I'm also thinking about the only Mana Tide Totem I run. Obviously it interferes with our game plan of pulling 477 with Guild Recruiter, but I don't want Guild Recruiter to be dead after we draw both Flamewreathed Faceless. What about Drakkari Defender? Any ideas?

Recently people are discovering the recruit combo in shaman like I did. Glad that some other people spot some light into this class. I like @Wumbostyle 's list (link: http://www.hearthpwn.com/decks/1022138-new-archetype-recruit-control-shaman), and I almost feel like reducing the spellstone might actually be helpful, because we don't have a lot of card draws and winning by spellstone is getting increasingly rare in my recent piloting. However, because Snowfury Giant and (hopefully) Greater Sapphire Spellstone compose our key combo, I decided to keep it as its original flavor.

In this recent update, I followed @Ex_Aquz 's advice and completely removed jade package to add in two Drakkari Defender, and they are performing really well. Thanks! Second Healing Rain added for its nice ability to heal the high health minions all over in our deck. You wouldn't find them stuck in your hand anymore. Two Far Sights may still be controversial but we do need spell form card draw because you don't want to get Mana Tide Totem out of Guild Recruiter. I'm also trying Fight Promoter. Will update the deck if he works well.

 It's been a long time! Since Witchwood I went ahead and played Shudderwock Shaman a lot because it's fun and interesting (not for the opponent though!). Now that Eureka! is released, I think this Giant Shaman thing can be revived again. I play-tested this current list several games at rank 4 and have won 3 straight against warlocks and hunters. Obviously the deck has changed so much that my intro and all other guides are no longer relevant, so I removed them, but I want to keep the revision history because adjusting decklist is plenty of fun, and pain of course. If I found more success with this deck, I'll update the guide.

Double Acolyte of Pain seem like an overkill. Most of the time you will have enough card draws, and an extra minion in hand is just an extra burden for playing Eureka!.

A Zap! is added for its much-needed flexibility, but the deck sometimes still feel clunky when facing against aggro decks.

Against potential aggressive decks (Warlock, Paladin, Rogue): Drakkari Defender, Acolyte of Pain, Zap!, Lightning Storm, and Lesser Sapphire Spellstone if you have Drakkari Defender. Storm Chaser is fine if you go first. Can keep Healing Rain against rogue only when you already have a decent starting hand.

Against all other classes: Drakkari Defender, Acolyte of Pain, Far Sight, Storm Chaser, Lesser Sapphire Spellstone. Keep Earth Shock against hunter.
