This is the best and funnest combination of Mill Shaman thus far.  I LOVE this deck.  I have created and played many versions of this deck but I find this one to be the best.  295 fatigue damage.  C'mon!  Can we say overkill... LMAO!!!

YEAH!!

Guide is a work-in-progress.  I am tired and going to bed.  Not all cards are included in the guide yet and a portion of is marked as belongs to another deck.

Mill Shaman V 2.0

This deck is SUPER FUN but also requires an Intermediate to Advanced Player to play this deck.  To get the combo out there I will put this deck around a 5 - 7 out of 10 in hard decks to play so if you are not a good player, don't waste the dust.  Remember, Shudderwock is consistently inconsistent.  I have played so many games where he repeats Grumble, Worldshaker first and the Baleful Banker next and the Doppelgangster.   This deck still gives you the opportunity to win in that condition however.  If you are an above average to good player and you want an awesome deck to play, here is that deck you've been looking to play!!!

You mill your opponent strictly off the Dancing Swords.  You want those guys to die as fast as possible.  You don't want them getting hit by Polymorph, Devolve or Hex, etc.  If you have the opportunity, you can use Baleful Banker on a Dancing Swords but be careful, it will draw more cards for your opponent at the end of the turn but might take away from your much needed Tunnel Blaster when you are playing Shudderwock.

Shudderwock, Da Undatakah & Grumble, Worldshaker make this deck a reality.  This is a wild only deck because of Doppelgangster and Dancing Swords.

I do not know how well this deck will fair in ranked because of all of the aggro decks but it fairs well against most of the aggro decks in casual.  The only deck that this deck seems to consistently lose against is Mill Rogue.

Core Cards
If you do not have these cards, you cannot play this deck.
1. Dancing Swords x 2 - Synergy with Da Undatakah
2. Doppelgangster x 2 - Duplicates Shudderwock
3. Grumble, Worldshaker Legendary - Synergy with Shudderwock.  Returns copies of Shudderwock to your hand and they cost 1 mana.
4. Da Undatakah Legendary - Another key player. Synergy with Dancing Swords, Tunnel Blaster & Shudderwock
5. Shudderwock Legendary - Our final key player.  Repeats all battlecrys that have been played that game (Except for himself).  We love you Shudderwock.  You make playing Hearthstone fun!

Helpful Cards
The deck will be extremely difficult to play without these cards
1. Acolyte of Pain x 1, Far Sight x 2, Mana Tide Totem x 1 - These cards are great for card draw.  You cannot replace him with a deathrattle or a battlecry minion because you will screw up Da Undatakah and Shudderwock.  You may be able to replace Acolyte of Pain or Mana Tide Totem with Cult Master but there are a lot of times where you just have no minions on the board so I don't know how much help Cult Master will be if that happens.
2. Acidic Swamp Ooze x 1 - Deals with weapons.  I chose this because it's a low cost 2 mana card that gives you a battlecry to remove a weapon from your opponent.  He has synergy with Grumble, Worldshaker easier than other weapon removal cards.
3. Devolve x 1 - Deals with aggro or murloc decks or other bigger minions.
4. Healing Rain x 2 - Healing.  Your entire objective is to stay alive.  You NEED healing.
5. Hex x 1 - Deals with big minions.
6. Baleful Banker x 1 - Synergy with Shudderwock and Armored Warhorse. He throws a copy of a minion back into your deck.  You want all minions out of your deck, if possible, before you play Shudderwock so you can throw just Shudderwock cards back into your deck.
7. Lightning Storm x 1 - Deals damage against Aggro or Super Aggro decks.
8. Brrrloc - Synergy with Shudderwock.  Freezes a minion.  This is mainly an important card for Shudderwock to freeze the opponent's hero for weapon decks if you haven't played Acidic Swamp Ooze yet.
9. Witch's Brew x 1 - More Healing. 
10. Volcano x 1 - Area of effect. Board clear.
11. Armored Warhorse Has synergy with Baleful Banker, Prince Valanar & Shudderwock.  Looks at two cards in the deck, if yours is bigger, gives your minion charge.  Now, this animation on this takes forever and that wastes your time.  That is the only reason you may want to take this card out but it is a 4 mana card that's easy to play and get out of your hand which is why I kept him when someone suggested him to me.
12. Hagatha's Scheme x 1 - This is a great card for a quick and easy board clear. I always keep this or try to have this in my opening hand when I mulligan.
13. Ancestral Knowledge x 1 - I know how people feel about this card being that it only draws two cards and doesn't have the value for the mana cost and overload but this deck needs card draw and this card does not mess with Shudderwock or Da Undatakah.  It is extremely beneficial and has bailed me out of many a mess.  I either play this card with 2 mana depending on who I am playing against or I play it as a late game card draw or when the board is looking bleak.

Replaceable Cards
This card can be replaced but helps with filling up your opponents hand with useless coins so they burn cards.
1. Volcano x 1 - This can be replaced for another Hagatha's Scheme.
2. Hemet, Jungle Hunter - This card can be removed from the deck but it is extremely helpful for clearing your deck fast.  I usually play him after I have Far Sight in my hand and have played at least 1 Doppelgangster.  (I don't keep Far Sight in my hand to wait for this card most of the time.)
3. Evolve x 1 - This card is a double edged sword.  It gives you minions that causes you opponent to remove immediately and surprisingly enough they can most of the time, it has awesome synergy with Doppelgangster, is easily gotten rid of out of your hand if need be but it also sometimes gives you unwanted deathrattle minions that take away from your end game.  You could win strictly on the minions it gives you or you could screw up the shudderwock calls.  This can be removed from the deck and replaced with more removal cards. I would not replace it with another Hex because there are already 2 other 4 mana cards in your deck and you want those out before you play the boss.  Be careful or replacing it for anything that cost over 3 mana. You want to be able to remove this with Hemet. 

===========================================================================
Anything beyond this point is from another deck and should be ignored - I am tired and am going to bed.  I will finish this later this week.

Objective
1. Play 2 Dancing Swords and let them get killed.  If you haven't played them before Shudderwock, this is not an instant loss.  They simply have great synergy with filling up your opponents hands with cards if you have been able to play Da Undatakah.
2. Play Sergeant Sally and let her get killed.  Watch out for priest cards that steal her.  I play her turn 3 if I have her.  She gets killed easily.  People get so confused when you play her because she is normally considered a useless legendary.  They don't get it until you play Da Undatakah and then still don't get it because 9 times out of 10 they kill Da Undatakah clearing their board without hitting face first.  When you start playing Shudderwocks and clear their board, then they get it.
4. Play Grumble, Worldshaker and let him get killed.  People go after this card with a passion.  They are so sick of the original Shudderwock deck, they don't want you playing Zola the Gorgon to bring him back to your hand.  They will use 1 - 4  cards from their hand to kill this one.
5. Play Leatherclad Hogleader and let him get killed.  People get very confused when you play this one.
6. Play Da Undatakah and let him get killed.  (If you have already played Leatherclad Hogleader, Doppelgangsters and Coldlight Oracles and this card happens to be the last card in your deck or close to it, you can play Shudderwock to gain the charge effect to either board clear without playing this card otherwise play him and let him get killed.  Don't fret if he gets silenced.  You are not after his deathrattle.  All you want is the battlecry. 
7. Play Baleful Banker and let him get killed.  You don't have to play him on anything.  You only care about the battlecry. 

Combo & Synergy Plays
1. Playing and killing Sergeant Sally prior to playing Da Undatakah will give you an 8 damage deathrattle on Da Undatakah.
2. The deck has a lot of card draw but if you want to get through your cards faster it is better if you don't play Baleful Banker on any cards.  If you throw cards back into your deck then it is less likely to pull your core cards when you need them.
3. If you are going to play Baleful Banker on someone the best minions to play him on are Doppelgangster, Leatherclad Hogleader, Da Undatakah or Shudderwock.
3. Da Undatakah is not a necessity to win if you have played Leatherclad Hogleader.
4. Booty Bay Bookie & Coldlight Oracle combination is a powerful combination.
5. Playing more than 2 Coldlight Oracle cards will screw with your Shudderwock so use caution if he gets thrown back to your hand or you are considering using Baleful Banker on him.  He does help with card draw so there is immediate benefit but it may come back to bite you in the butt when you play Shudderwock.
6. Immediate benefit from battlecry minions is helpful but not necessary for this deck.
7. Play Da Undatakah even if you have not played any deathrattle minions.
8. The hardest cards to get out of your hand are Leatherclad Hogleader, Grumble, Worldshaker & Da Undatakah.  I play these as fast as I can depending on the board.  I do not wait for any benefits from these cards.
10. Playing 2 Da Undatakah battlecries will help out immensely when you play Shudderwock.  So if gets Sapped back to your hand or you can play Grumble, Worldshaker while he is still on the board is fantastic!  Shudderwock would then potentially take on 4 Dancing Swords and 2 Sergeant Sally effects if the battlecries are repeated correctly.  This means, 5 Shudderwock minions that gets destroyed by Brawl or the Grumble, Worldshaker battlecry, for example, each with your opponent draws 4 cards and do 12 damage per Shudderwock to their minions on the board. Oh, Glory Days! :D FEEL THE BURN!!
9. This deck doesn't care if your hand is filled with 1 mana Shudderwock cards like other Shudderwock decks.  If all battlecries were played perfectly in order, Shudderwock will take on the deathrattle of two Dancing Swords (and potentially Sergeant Sally), then multiply himself to have 5 of him on the board, draw cards until your hand is full or close to full, send a copy of himself to your deck, and then return all of the copies of the Shudderwock minions back to your hand burning 3-4 of them causing your opponent to draw 6 - 8 cards and causing 18 - 24 damage to all minions on their board.  You then play the last 1 mana Shudderwock to do it all over again.  If Grumble, Worldshaker is the first battlecry then you have the Leatherclad Hogleader to fall back on.  SO MUCH FUN!

Win Conditions
This deck has multiple win conditions but most revolve around Shudderwock.
1. Non-Shudderwock Win: This deck has some pretty powerful minions and remove spells to stand on its own against most control or midrange decks.  There are numerous occasions where I have won just because I have board control.  They concede or I win and never played Shudderwock.
2. Milling your opponent: This is the objective of the deck.  When you play Shudderwock, you mill the hell out of your opponent.
3. SMOrc: When you play Shudderwock, you put cards into your opponents hand with the battlecry from Coldlight Oracle, Booty Bay Bookie, and the deathrattle from Dancing Swords, clear their board with the deathrattle from Sergeant Sally and SMOrc face with the battlecry from Leatherclad Hogleader.

Notes from Creator
The deck is extremely fun to play.  I hope you have as much fun as I have had with it.  Good Luck. I have attempted over 100 different combinations and variations of this deck and this is the best one by far.  It is an expensive but there is nothing else out there like this deck.  I don't play much ranked but if you hit Legend with this deck, I want to know about it so don't forget to come back here and tell me.
