Hi guys, I'm SnakeEater an italian player. First of all excuse me for my bad english, 

This is my version of RenoLock filled with the new warlock's legendary Krul the Unshackled so i named it KrulLock.

If the deck will receive +30 upvotes i will make a FULL MULLIGAN GUIDE.

I hope you enjoy the deck. :D

EDIT: Fearsome Doomguard doesn't work. Most of the time was only a "more win" condition so I decided to swapped it together with Bloodfury Potion for Leeroy Jenkins and Faceless Manipulator.

Summary

• Card Choices;
• Tech Changes;
• Best Combos;
• Gameplay;
• Mulligan Guide (General)
• General Advices

Card Choices:

Mistress of Mixtures: Strong 1 drop minion that heals since the beginning of the game when you need to life tap the most;

Mortal Coil: Removal for little minion that also draw cards;

Power Overwhelming: Piece of the combo and sometimes great with Shadowflame for a board clear killing a small minion like Mistress of Mixtures

Acidic Swamp Ooze: In ladder there are a lot of  weapon-based deck so this card is a must; 

Dark Peddler: Great 2 drop minion that can discover great card like Soulfire, a second Power Overwhelming or, in same cases, Corruption;

Doomsayer: to stop aggro start;

Sunfury Protector:  Give taunt to the big one in the deck is one of the best way to block aggro decks;

Earthen Ring Farseer: Heal is important in this deck because with Life Tap your Health decrease very fast;

Imp Gang Boss: Simply the best 3 drop minion and is also a daemon;

Shadow Bolt: For the beginning of the match when there is a threat to remove. I prefer this one than Blastcrystal Potion because we need to remove stuff in the beginning of the game. In late game we can use our AoE o card like Siphon Soul;

Defender of Argus: Same as Sunfury Protector;

Faceless Shambler: Great to use in combo with Power Overwhelming before the attack;

Hellfire: Great AoE and in some cases even a finisher against deck like Freeze Mage;

Kazakus: Great card, one of the most useful I ever seen. In every condition this card may help you with an Aoe, with a single removal, gaining armor or reviving dead minions; 

Refreshment Vendor: Strong heal card in the beginning of the match;

Shadowflame: Second AoE great with Power Overwhelming;

Twilight Drake: After lifetap on second and third turn this will be a 4/9. Great card to give taunt or to use as a target for Faceless Shambler;

Doomguard; This card can have 2 uses: Combo with Krul the Unshackled or extra damage to close the game;

Faceless Manipulator: Combo card with Leeroy Jenkins or, in same cases, to copy taunt minion;

Leeroy Jenkins: Combo card for the finisher;

Emperor Thaurissan: Combo card for the finisher. It's also great with Lord Jaraxxus to play it at turn 10 together with a 6/6 Inferno;

Kabal Trafficker: Synergise well with Krul the Unshackled and Mountain Giant decreasing his mana cost;

Reno Jackson: it's Reno...what can I say more? This is the card of the comeback;

Siphon Soul: Great card for remove BIG minion that also heal you;

Sylvanas Windrunner: Synergise well with Shadowflame and Power Overwhelming;

Abyssal Enforcer: A daemon 6/6 + Hellfire effect at 7 mana. Simply amazing. When you already have the board control you can wait until you have Krul the Unshackled to non trigger the battlecry;

Twisting Nether; The strongest AoE on HS. Useful to clear the board and prepare the field for Krul the Unshackled;

Krul the Unshackled: Great card, in the worst scenario you can play for 9 mana a 7/9 and a 2/4. Honestly most of the time you will play Krul the Unshackled together with the Doomguard and another daemon from the Kabal Trafficker. It's very difficult for the opponent to come back after a turn like this.

Lord Jaraxxus: Useful card to restore your health or to use in combo with Krul the Unshackled and one between Sunfury Protector or Defender of Argus for a big taunt minion;

Mountain Giant: Synergise well with life tap in fact you can play this card on turn 4 after 2 turn of hero power or one only if you have the coin.

Tech Changes:

If you encounter a lot of aggro you can make this changes:

• Mountain Giant for Mind Control Tech
• Leeroy Jenkins for Sergeant Sally for another AoE in combo with Power Overwhelming
• Faceless Manipulator for Kabal Courier [thx to Rapidosamurai for the idea]

You can also swap only Mountain Giant for Sergeant Sally keeping the combo in the deck

Best Combos:

Krul the Unshackled + Daemons: This is a very strong combo that synergise well with Kabal Trafficker;

Leeroy Jenkins + Faceless Manipulator + Power Overwhelming + 1 turn of Emperor Thaurissan: Finisher of the deck, it's more simple that it seems because you need to decrease the cost of one card only to make 20 damages in one turn;

Lord Jaraxxus + Emperor Thaurissan: At turn 10 set your hp to 15 and summon a 6/6 Inferno;

Sylvanas Windrunner + Shadowflame: Clear the board and steal a minion;

Faceless Shambler + minion with Power Overwhelming: Big taunt minion;

Mistress of Mixtures + Power Overwhelming +Shadowflame: Heal yourself and clear the board;

Gameplay

I think that the better way to explain how the deck works is to divide the game in sections:

Turn 1-3: You want to life tap to gain card and meanwhile heal yourself with card like Mistress of Mixtures or Earthen Ring Farseer. Don't play Mistress of Mixtures on turn 1, you need the 4 Health so play it on turn 3 after 2 turn of life tap;

Turn 4-5: Here you can start to play big threats like Mountain Giant and Twilight Drake or if needed clear the board with Hellfire orShadowflame;

Turn 6: Here you need to analyze the board and the opponent deck. Vs aggro probably you will need to play Reno Jackson while Vs Midrange o Control you will play cards like Sylvanas Windrunner, Kabal Trafficker or Emperor Thaurissan if you had one of the 3 card useful for the finisher;

Turn 7-8: If you already don't have it, take the control of the board with your AoE or with Abyssal Enforcer. Otherwise if you had the control of the board stabilize it doing some trades or playing a taunt or a big minion;

Turn 9-10: It's time to close the game, here you can play Krul the Unshackled with the daemons in your hand or use the finisher with Leeroy.

Mulligan Guide:

Always search Twilight Drake, Mountain Giant, Reno Jackson and a heal card like Mistress of Mixtures or Earthen Ring Farseer. Keep also the Mortal Coil against classes that plays since the beginning small minion

General Advices:

• Vs Aggro try to not abuse your Hero Power, is the best and simple way to win the game;
• Never play Mistress of Mixtures on turn 1, you need the 4 point of health. Wait at least turn 3;
• Remember to count the card in your hand when you play Kabal Trafficker. Most of the time is a good idea to stop using Life Tap when he is on the board;
• Learn to use Kazakus:
  • Most of the time is a good idea to choose the 5 mana spell to play on curve or, if you have the coin, the 1 mana spell to decrease the opponent pressure;
  • Vs Aggro choose Armor + Board Clear or Summon a Daemon;
  • Vs Control Revive your minion + make X damage;
  • Vs Control if you had in your hand Krul the Unshackled and all your daemons and the Kabal Trafficker are still inside the deck you can also add some daemons in your hand;
