The Epitome of Deck Design / The Deck of a Thousand Combos / The Most Complex & Fun Deck Out There

Deck description: Infinite Adaptation & Complexity. You copy the Wincondition of your choice depending on matchup forever. You adapt from one combo to the next, choosing between infinite options each turn for maximum enjoynment. Every card has a purpose. More combos in deck than cards in deck. 40 card variant exists but is way less smooth and enjyoable. And I cant guarantee its winrate. Deck Concept is applicable to rogue, mage, warlock,  shaman and possibly druid..

Decks it beats easily:    
     90% winrate vs Big Priest, any version including Neptulon, 80% vs any other Priest variant. This deck is literally the priest destroyer. The Ultimate Priest atop the Priest Foodchain, feasting on their souls and faith.
    Every quest hunter. 
    Mech Paladin.
   Weapon rogues.
   Every Shattered Cthun. Bonus points if they are 40 hp.
   Armor druid. 
   Meme decks like mine warrior, swap hp/stats warlock.
   Big Anything, really, from Druid to Hunter.
   Dragon anything.

Decks that can give trouble but are beatable:
    Mech Mage. 
    Discover mages/rogues. /but its difficult and takes away your soul.
    Curse Warlock. (very hard!. Depends a lot on what you overdraw)
    Tickatus Warlock. You need to refill your deck.

Decks you arent ever going to beat. 
    Most shamans.
    Every pirate aggro
    Most Murlocs.
    Timewarp mage. 
    Toggwaggle unless you play perfectly and end with Gulper on board when they toggle, with nothing in your hand to kill the gulper. But tools like seanse to help the gulper dominate. The deck doesnt have too many cards to deal with it in return once they switch decks.
    MechaThun Rogue ect.
    Small Nep Rogues that kill you before turn 4-5.

Variants of the deck exist, from 40 cards to adding more tools vs early aggro. ShadowLash+talented arcanist is strong for 4 mana area clear that heals you for 26-30 hp..   there’s the option to replicate Vargoth ->spellpower->mindblast. But these are likely not the best variant.

Cards I’d add, which I don’t yet have the dust for: Raza (Questionmark. You aint inspire comboing with him, but you can jaraxxus spam for 0 mana. Not great in respool but not the worst.)
New must include legendaries from next patch.
Option for ShadowReaper Anduin. But its not a necessity I think. 
Possibility of Rat if you start facing decks you need it for. But its a dead card/lose condition vs half of them, and you dont want to res it. Lowers winrate.

Cards I’d replace: Drown+Auspicious Spirits. They are filler. Drown is good vs some things that require hard removal and can appear early, like Vargoth. Auspicious Spirit is just a filler, and could easilly be replaced with something else.

You arent reaching Legend with this one, not without augmentations. But its still on the works. The concept is solid. More dust=you can play around with it. Concept is applicable to 

Explaining some combo situations:
    If enemy is weak vs Moonfang: repeat it. Also. Moonfang+Apotheosis=unkillable healer vs wasted hard removal/non hard removal. Scout their hand and use it., its a Wincondition on its own.
Brann+ kazakus+seance on either.->2x 10 mana potions for the mass polymorph&mass resurrect for more moonfangs/Behemoth&vargoth is the best you can do. 5 potion for 1 turn vargoth->14 armor + area clear ect can be strong. This is your second strongest and possibly strongest lategame combo.

   Brann/Seance+ Ambassador->finley. this is lethal vs half the decks. You get your hand full of colossals to spam every turn. Add Jaraxxus and you can probably cast the hero power every turn as well. Jaraxxus+finley is the optimal.  jaraxxus outvalues a full colossal hand on its own, so make your conclusions how comebackable a control matchup is at this point. BUT some decks DO outvalue it, so then you want to keep further ambassadors in store.

   Zephrys is adaptable. Use it well. Jaraxxus is strong vs a lot of things, like every priest. But then you may wanna early cast it vs aggro/secrets. Double seanse is a problem for that, but its never a problem otherwise. You can switch it for zola, but I dont recommend it. Zola is a win more card, and you are already winning hard if you are winning. But yeah. Careful with the mana. Low mana at 8 mana=higher chance of jaraxxus.

   Vargoth->anything, and you get value. Raise dead/eternal servitude could mean double value for you without having it on hand.
   Taelan brings you behemoth/Reno. And trust me, removing behemoth is not going to win you games. Behe is a situationally must have card, seansing it can be crucial, and its way more adaptable vs certain board spam situations ect. than reno can, where youd just end up getting to 5-10hp each turn anyway with reno. Even if you did need reno, having it almost always guarantees you survive till you draw reno as well, and you can resurrect taelin.
   Spirit of the dead is insane. Use it well. It justifies early use of kazakus/zephrys in matchups you also want to use them late, but need tempo/cant afford or dont have a seanse & perhaps expect your res pool to fill with crap before you could get to res them.
   Psychic scream. You are getting a kraken/mass polymorph at some point. You will end up throwing enemy deck full of 1/1s if they dont prompt you to throw their board there otherwise.
    LightBomb/Dragonfire = searchable, adaptable. Usable.    
    Loatheb: wincondition vs any mage. just keep spamming them, and watch the quest spell hunter cry bloody tears. Usable with greedy moonfang/Vargoth plays.
   Reno. Bloody obvious what you want to do with it.
40 card variant has more combos. But is less fluid. Make your conclulsions.
