As of now, everyone considers Warlock to be the worst class in the game. I decided to challenge this and came up with an interesting deck with good results!

The playstyle of this deck is near identical to the classic Renolock. You make use of Warlock's Life Tap to find the cards you need, healing yourself along the way. Eventually, your opponent runs out of steam or you overpower them with Jaraxxus value.

Aggro: Mulligan for AoE and early game drops such as Mistress of Mixtures, Doomsayer and Tar Creeper. Depending on the matchup, you may want to keep cards like Hungry Crab or Gluttonous Ooze. Life Tap when necessary, but be very mindful when doing so. You'll want to also be smart with your AoE, but never too greedy. If played right, your opponent should run out of steam and you can stabilize the board.

Control: Mulligan for mid-game cards like Kabal Courier, Twilight Drake and Kazakus. Depending on the matchup, 1 drops, soulfire, corrupting mist and Doomsayer may be worth keeping. Try to make value oriented plays, but also make sure to fight for board control. Your main win condition is Jaraxxus, so you typically want to play him as soon as possible.

The best matchups are Hunter, Paladin and Shaman. This is because this deck tends to obliterate mid-range (when played right).

The worst matchup is Jade Druid because we simply cannot beat the endless value. Pirate warrior comes in 2nd because you desperately NEED good draws.

                              

Card Explanation:

Kazakus: I always felt like Renolock was one of the strongest and most fun Warlock archetypes. Since the retirement of Reno from standard, Kazakus is the closest thing to Reno that there is. While the Kazakus can't heal like Reno, he does bring a lot of flexibility to the table. He can give you a shit ton of armor, clear the board and/or fill the board with minions. With that being said, he is also one of the best "heals" in the deck, with the Kazakus spell giving up to 10 armor.

Black Knight: From Thing from Below to Tirion, this meta is filled with taunts! With the rise in popularity of Stonehill Defender, decks who generally did not run taunts now have access to a variety of them, thanks to this washed-up teenage mutant ninja turtle.

The Curator: This card helps immensely with the curve and is a nice taunt. Against aggro, playing Curator on turn 7 into Primordial Drake turn 8 can be game-winning. It's also quite useful for drawing our Ironbeak owl for quick silences or Hungry Crab against those late-game murlocs.

Cards to Consider:

Golakka Crawler: If you're facing an annoyingly large amount of pirate warriors, bring Mr. Krabs out.

Stonehill Defender: Great value against control decks, but weaker than Tar Creeper vs Aggro; depends on the meta.

Chittering Tunneler: Weaker version of Kabal Courier. However, might be worth taking if you want more value vs control and synergy with The Curator.

Eater of Secrets: If Mage/Paladin secrets give you a hard time, consider this spooky guy. Although with the right plays, you should be able to beat both classes without this card.

DOOM!: If Kazakus spell, AoE, and Twisting Nether are not enough removal, then this may solve your problems.

Mountain Giant: Quite strong against slow control matchups. On the other hand, this tends to be a dead card vs fast aggro decks; really depends on the meta.

Leeroy Jenkins + Faceless Manipulator: I used to run these 2 cards as a finisher. It can be really good against mid-range or control decks. However, the combo is usually slow and awkward, especially against aggro.
