Hello people.

You got sad cause you packed Dr. Morrigan from pre-order? Don't despair, I got your back.

First day of expansion is great for memes and I tried this with Malchezaar (of course it didn't work). I did see some consistency here and there, so I tried to tinker this N'Zoth Renolock to work at least in a decent way.

And oh my god, it seems to work, in spectacular fashion.

This is a classic Control Renolock, in N'Zoth variant. No cheesy Cubelock. Goal of the game is to outlast the opponent finishing him with one of the many win conditions that this deck has to offer.

Key win condition cards:
Kazakus
Right potion(s) at the right moment can seal the game.
10 mana potion can reset a horrible board, generate insane value, deal final blow, stall the board for a turn.
5 mana potion will often bring a strong tempo swing, average board reset or deal with critical targets.
1 mana potion, even if often overlooked, can be a saving grace in tight situations and become the beginning of taking control of a hard game.
Comboing Kazakus with Brann or Zola can help with consistency of the potions or to generate, but it's not mandatory. I would advise against using Baleful Banker on Kazakus, because you don't want him to be pulled by Dr. Morrigan and has better targets.

Reno Jackson
Of course, the main reason you play Renolock.
Learn when to play him or to keep him in the mulligan. He's the most important card you have and your key win condition for fatigue games. Not to mention how he singlehandedly wins you games against specific types of deck like Burn Mage or Aggro Paladin.
He is generally going to be your designed target for Zola, as for 9 mana you will get back to full health declaring to your opponent that if he wants to kill you he has to win the fatigue game.

Gul'Dan the Bloodreaver
Our beloved DK, strongest of them all. In this deck you are generally going to play him defensively to create a barrage of taunts or resurrecting Mal'Ganis. Playing him is usually the turning point, opponent will have to deal with the new board you summon and will have to manage your embarassingly strong hero power.
Don't be scared to play him just to summon fewer demons that might still be the key to not lose the game or change the situation drastically.

N'Zoth the Corruptor
Praise N'Zoth. Playing him will usually result for the opponent in a nightmarish board to deal with in this specific deck, which can be dealt efficiently only through mass polymorph.
Depending on the flow of the game, he's going to be the reason you win the game.
The biggest problem for your opponent isn't the fact that you brought a full board which protects you from being hit in the face. In this specific deck, you will win if the opponent can't double clear your board, which is fairly unlikely for him to do.
Clearing the N'Zoth board will result in Sylvanas stealing stuff, Thaddius to be summoned one or two times (22 damage post hard reset means usually you dead), Voidlord and Belcher protecting face and key minions, Dr. Morrigan to go back in the deck and pull threats on the board.
This kind of board is possibly the hardest and most dangerous board to clear in the entire game, along with the cubelock one.

Thaddius
Feugen and Stalagg can be really hard to get to work, and they almost never saw play because of the big tempo loss represents playing them on curve and how easy they are to neutralize, through silences and morphs.
The point of playing them is that this deck, thanks to the insane control tools at Warlock disposal, can afford such tempo losses. Warlock has Shadowflame, which allows you to clear the board AND summoning Thaddius in the same turn.
The reason these two guys work is that actually your opponent has to deal with so much shit that neutralising them means losing answers to other threats. Like Mal'Ganis, Dr. Morrigan or Kazakus.
They can be resurrected via Kazakus. They can be copied with Zola or Banker, or pulled by Morrigan. One way or another, if you don't get killed before, you will eventually get to summon Thaddius. And Thaddius is a big bad mofo. But it's not just that.
Feugen is a good control trading tool and he's likely to stay on the board for more than a turn. Stalagg can hit hard face or remove high health minions efficiently. They will take removal resources off of your opponent's pool very efficiently. Stalagg in particular can become very dangerous when summoned back by N'Zoth and he's protected by taunts.

Dr. Morrigan
This is the reason I made the deck, after finding it in a pack.
This card is weird, but I think it manages to do what previous experiments have failed. (See Madam Goya). What makes this card a win condition in a Control deck like this is resource depleting for other threats. And after playing it I do notice that 8 mana that can seem excessive it's actually fair. The synergy with Baleful Banker and N'Zoth is really something to behold. At it's full potential, you will get a Dreadsteed effect off of this card. With 5/5s.
Getting Morrigan killed in YOUR turn can cheat for 0 mana Sylvanas, Feugen, Stalagg or Mal'Ganis. That could mean that with the right stuff in your hands, your N'Zoth board will become the nightmare you aim it to be.
Just be mindful when you play this card of the current state of your deck. Do not play this card before having N'Zoth or Reno in your hand generally (you can consider it if you are positive that if these targets will last on board if they get killed and you have Zola or Baleful Banker ready.)

Gnomeferatu
Strong early game minion that can become your key to victory against some opponents.
If you suspect you are playing against a Combo deck, try to maximize it's efficiency by pairing it with Brann and Zola. For 10 mana by playing Brann, Gnome, Zola on Gnome and Gnome again you can burn FOUR cards. Even Two cards is fine. If Gnome fails, you still have Dirty Rat to disrupt some combos.
Which can easily mean that you will get to burn a combo piece, as usually they are not in the opponent's hand in the early game as they are mulliganed away almost all the time.
This is when you actually plan. Sometimes you just play him randomly and get to burn Jaina.
KEEP THIS CARD UNTIL END GAME IF YOUR OPPONENT IS A KINGSBANE ROGUE.

Brann Bronzebeard
Brann will be considered a high priority target at all stages of the game by your opponent, take advantage of it. Do not be scared to play him on curve in aggro match-ups as usually will lead to bad trades from the opponent or will soak removal.
He is also a great pull from Dr. Morrigan, as if he gets to the board and stays there, you can do insane stuff, like Gnomeferatu+Zola+Gnomeferatux2. Kazakus+Zola+Kazakus. (And you are totally free to spend a turn doing this against decks like Control Warrior or Reno Mage)
Reno Jackson+Zola for ragequit.
Main combos:
-Kazakus. More potions. Brewing multiple potions throughout the game is a very strong win condition.
-Zola the Gorgon+Other targets. More copies of key minions like Reno, Mal'Ganis, Sylvanas, Sludge Belcher, Doomsayer, Kazakus, Voidlord, Despicable Dreadlord Feugen and Stalagg.
-Baleful Banker+other targets. WTF YOU NOOB YOU A RENO DECK. Yes you are. but doing this on Kazakus or Reno does not harm you if you don't have the other in your hand or you are not in a hurry of playing them.
And there will be situations where it will still be a good idea if you have. Dr. Morrigan can get the extra copy of what you banked out of the deck, even if it's stuff like Belcher or Gnomeferatu your opponent will be mind blown as he will not play around the Reno effects if he knows you have duplicates.
-Dirty Rat. Possibilities are endless. Pairing this combo with a Doomsayer is particularly effective. King Togwaggle, N'Zoth, Reno Jackson, Shudderwock and Dirty Rat itself will hate you a lot.
-Gnomeferatu. Some people just want to watch cards burn. Some people ragequits when you burn a DK, a combo piece or Dr Boom Mad Genius. And other lose anyways when you burn their key damage, buffs or removal.
-Kobold Librarian. In case you need emergency card draw or want to buff and play your Lesser Amethyst Spellstone to the full straight away.
Do not do this if your Health pool is not safe unless you are about to lose the game if you don't draw an answer. Do not do this in Control match-ups unless you are sure to win by playing N'Zoth or Gul'Dan next turn. This concept also applies to your Hero power, very often you will want to have as much space as possible for Kazakus/Zola shenanigans.

EDIT 1: Baleful Banker, while being awesome fantacombo enabler ended up being redundant or useless most of the time, while Siphon Soul proves to be AMAZING single target emergency removal.
Currently reached rank 6 after this change.

I will add more stuff to say later.

Match-ups
Kingsbane Rogue (even/unfavored)
You have two ways out of this.
Mill Kingsbane with Gnomeferatu.
Early Skulking Geist helps.
Pressure with big boards. If you manage to drop Feugen and Stalagg together and get them killed by Vanish you won.
