06/09/2018: - Krul the Unshackled, + Giggling Inventor. I don't think Krul the Unshackled is strong enough anymore, because summoning him along with Mal'Ganis and Voidlord is pretty rare. In most situations you only get one of those two plus a 7/9 demon for free, but this isn't really needed: now that the deck runs the Mecha'thun package, dealing face damage is not that important because you want to finish your opponent with the combo. Krul the Unshackled has bad synergy with Voidcaller and, finally, drawing this card against an aggressive deck is really painful. On the other hand Giggling Inventor is a card that I really wanted to add in this deck, because it's a standalone insane card, similar to Sludge Belcher and Rotten Applebaum. Giggling Inventor has pretty good synergy with Defile and Zola the Gorgon and will definitely improve the aggressive match-ups.

18/08/2018: - Dark Pact, - Power Overwhelming, - Ratcatcher, - Rin, the First Disciple, + Bloodbloom, + Cataclysm, + Emperor Thaurissan, + Mecha'thun. Removed the Rin, the First Disciple package in favour of the new Mecha'thun package, which is definitely easier to achieve and provides an immediate result (your opponent's defeat, literally). Once removed Rin, the First Disciple, I found that Dark Pact, Power Overwhelming and Ratcatcher were the least impactful cards (they have great synergy with Sylvanas Windrunner, but that is all), so I removed them to fit the 4 Mecha'thun combo pieces in the deck.

09/08/2018: - Mortal Coil, - Plated Beetle, + Dark Pact, + Ratcatcher. I decided to replace Mortal Coil with Dark Pact because a ping and a draw are not needed as much as an extra activator for Rin, the First Disciple that can be used as an extra healing source, too. Ratcatcher is an interesting card that can be used to make efficient trades, as a deathrattle activator or both things simultaneously. It takes the place of Plated Beetle.

20/05/2018: - Dark Pact, - Demonwrath, - Loatheb, - Emperor Thaurissan, + Power Overwhelming, + Plated Beetle, + Rotten Applebaum, + Rin, the First Disciple. Since Dark Pact is being nerfed, I've decided to use Power Overwhelming instead, which is very useful to make value trades, to trigger Rin, the First Disciple or Sylvanas Windrunner's deathrattle. Demonwrath is not good enough and it is basically ineffective when playing against a Warlock, so I decided to replace it with Plated Beetle, which is a great tool in aggressive match-ups, thanks to the 2/3 body and the armor gain. I also replaced Loatheb with Rotten Applebaum in order to maximise chances against aggro decks. Rotten Applebaum is in fact a great taunt card with a decent body and some useful healing. Finally, I decided to replace Emperor Thaurissan with Rin, the First Disciple in order to have another win condition against slow control and combo decks.

13/04/2018: - Abyssal Enforcer, + Demonwrath. I'm not removing Abyssal Enforcer because it is not a good card. The issue comes from the excessive number of high-cost cards in the deck, which reduces its consistency against aggressive decks. The inclusion of Demonwrath will definitely improve those match-ups. There are two more reasons that induced me to remove Abyssal Enforcer: first, the recent addition of Lord Godfrey, a minion that does what Abyssal Enforcer does, but better; second, the bad synergy with Voidcaller, Krul the Unshackled and sometimes even Bloodreaver Gul'dan, because you really want to get big demons on the board with these cards, such as Mal'Ganis and Voidlord.

06/04/2018: - Spellbreaker, + Krul the Unshackled. Community feedback induced me to bring back Krul the Unshackled. I removed Spellbreaker because this deck doesn't really need a silence, which can be useful only in specific match-ups.

30/03/2018: - Power Overwhelming, - Shadowflame, - Twilight Drake, - Krul the Unshackled, + Dark Pact, + Mistress of Mixtures, + Spellbreaker, + Lord Godfrey. I've included more anti-aggro cards to deal with decks such as Dude Paladin and Secret Mage. Mistress of Mixtures has a strong impact on the game when facing aggressive decks and Dark Pact provides significant healing, which is great especially against Secret Mages. Spellbreaker can help in several situations and, of course, in Cubelock match-ups. Lord Godfrey is definitely one of the strongest cards ever released for Warlock: it has the ability of clearing most of your opponent's boards, with an effect which is similar but stronger than Defile and, on top of that, it gives you a 4/4 body, thus not giving your opponent the opportunity to immediately develop a threatening board again. Temporarily replaceable with Demonwrath or one of the removed cards.

28/01/2018: - Dark Pact, - Lesser Amethyst Spellstone, - Spiritsinger Umbra, - Possessed Lackey, - Rin, the First Disciple, + Mortal Coil, + Dirty Rat, + Zola the Gorgon, + Twilight Drake, + Loatheb. Sadly recent changes haven't really improved this deck's overall performances, so I decided to cut most of the new cards. Dark Pact, Spiritsinger Umbra and Possessed Lackey are strong cards in the Cubelock archetype, but in Renolock they're not that good because there are a few valuable targets for the effects they provide. With the exclusion of Vulgar Homunculus I decided to cut Lesser Amethyst Spellstone, too, because there are fewer activators and it doesn't look necessary with Antique Healbot and all the other healing sources of this deck. Rin, the First Disciple has helped me to win only two games so far, so I don't think it is worth it to play this card. It's too slow in most match-ups and the tempo loss causes a defeat in most of the cases. I decided to bring Mortal Coil back because this deck really needs tools to stop aggressive decks from rushing you in a few turns: once you reach the late game and heal yourself, you're safe and sound. Zola the Gorgon can help in both aggro and control match-ups, copying key cards such as Kazakus or N'Zoth, the Corruptor that can win you the game. Twilight Drake is back, too, because it's the most efficient minion to play for just 4 mana, considering that with this deck you usually have a lot of cards in your hand. Finally, I decided to include Dirty Rat and Loatheb to have more chances to win against Reno Priest and other combo decks.

19/01/2018: - Mistress of Mixtures, - Vulgar Homunculus, - Twilight Drake, - Lord Jaraxxus, + Dark Pact, + Spiritsinger Umbra, + Possessed Lackey, + Voidlord. These changes should improve this deck's overall winrate, providing more deathrattle and demon synergies. Mistress of Mixtures was removed to include Dark Pact, which provides the same amount of healing, but is definitely faster than Mistress of Mixtures and can be used to trigger deathrattles, thus countering silence and polymorph effects. Lord Jaraxxus was removed because unnecessary in the current metagame and replaced by Voidlord, which has insane synergy with N'Zoth, the Corruptor, Bloodreaver Gul'dan and many other cards of this deck. Twilight Drake and Vulgar Homunculus have not that much synergy with the rest of the deck and thus were removed. Spiritsinger Umbra and Possessed Lackey took their place and have the function, respectively, to trigger deathrattles immediately and to cheat out big demons from the deck.

04/01/2018: - Sunfury Protector, + Rin, the First Disciple. I decided to include Rin, the First Disciple as an alternative win condition against control and combo decks. The absence of Sunfury Protector shouldn't hurt too much, because it hasn't been that necessary in aggro match-ups, which were decided by removals and heals. Moreover, I've always preferred standalone taunts rather than giving the taunt tag to an existing minion on the board, which is really powerful only with Twilight Drake, Lord Jaraxxus and Sylvanas Windrunner. Sunfury Protector is obviously a better choice if your facing only aggressive decks, but keep in mind that Rin, the First Disciple can be really helpful when you're dealing with slow decks and combo decks. Small demons summoned in the process might weaken the power of Bloodreaver Gul'dan, preventing you from summoning a second Mal'Ganis, but the chances of this happening shouldn't be too high because there are not that many demons in this deck.

04/12/2017: - Mortal Coil, - Imp Gang Boss, - Shadow Bolt, + Kobold Librarian, + Vulgar Homunculus, + Lesser Amethyst Spellstone. Since the Kobolds & Catacombs expansion is coming out soon, I've prepared some interesting changes to this deck. First of all, the inclusion of Lesser Amethyst Spellstone, which is an insane Warlock spell: it deals 3, 5 or 7 damage to a minion and restores that much health to your hero. In order to upgrade the spell, you need to play cards that inflict damage to your hero, such as Hellfire and Abyssal Enforcer, which is why I replaced Mortal Coil and Imp Gang Boss with Kobold Librarian and Vulgar Homunculus. To be honest, these replacements were not made solely for the synergy with Lesser Amethyst Spellstone, but also and above all for the value these two cards provide: the first is a 1-mana 2/1 which draws a card and the second a 2-mana 2/4 taunt demon. In both cases, the damage you take is not much compared to the benefits received. Therefore, Shadow Bolt was removed because it had the same function it now has Lesser Amethyst Spellstone, but was weaker; Mortal Coil, great ping which also draws a card, has been replaced by Kobold Librarian, that provides a nice body and has synergy with Lesser Amethyst Spellstone, too; Imp Gang Boss was a really strong early game minion indeed, but we don't want to dilute too much the pool of demons resurrectable by Bloodreaver Gul'dan with 1/1 Imps and Vulgar Homunculus is great in the early game, too.

29/10/2017: - Tar Creeper, - Piloted Shredder, + Sunfury Protector, + Twilight Drake. I decided to replace Piloted Shredder with Twilight Drake, because I think the latter is better for a deck like this. In fact, during the early game we usually tap a lot and get a pretty large hand, so you would get a lot of value from Twilight Drake. I know Piloted Shredder is a sticky minion and you can resurrect it with N'Zoth, the Corruptor, but the random 2-mana cost minion you get from its deathrattle doesn't have a lot of impact and could even lose you the game if that minion were a Doomsayer you didn't want to summon. I also changed Tar Creeper with Sunfury Protector, because there are a lot of cards that would be really strong with taunt, for example Lord Jaraxxus summoned with Krul the Unshackled, Sylvanas Windrunner, or the Twilight Drake just added. Finally, Tar Creeper is only good versus aggressive decks, whereas in control match-ups it's a mediocre card, thus Sunfury Protector's versatility is preferable.

19/08/2017: - Sunfury Protector, - Blastcrystal Potion, + Piloted Shredder, + N'Zoth, the Corruptor. Since the meta finally slowed down and people were having good results with N'Zoth, the Corruptor in this deck, I decided to include it. With the addition of Piloted Shredder, that is one of the stickiest deathrattle minions, it is guaranteed a solid mid game, at the same time empowering the late game value given by N'Zoth, the Corruptor. There are 6 deathrattle minions in this deck, but you can play N'Zoth, the Corruptor when just 3 or 4 of them died, it's still a good deal. Sunfury Protector is great with the Infernals you get from Lord Jaraxxus or the demons you summon with Krul the Unshackled or Bloodreaver Gul'dan, but in a lot of situations you don't take advantage of the taunt this card provides, so it isn't really needed. Against aggro decks, cards that have taunt on their own, AoE removals and heals are way better than Sunfury Protector, simply because they have a faster, immediate effect, whereas Sunfury Protector requires you to have played a minion without taunt to activate the effect it provides, otherwise a 2 mana 2/3 without effects is not a great deal. Blastcrystal Potion is a great removal in the late game, but in the early and mid game the drawback can be fatal, especially because of all the high cost cards included in this deck. Plus, there are a lot of single target removals in the deck, so Blastcrystal Potion isn't needed.
