[AoO] Easy Diamond Suicide Warlock

I made this deck after SoU when Neferset Thrasher and Diseased Vulture got released and it was a decent deck at the time but now with Darkglare and Soulbound Ashtongue it became insane!  Darkglare is the star of this deck, that card is a beast. 

Edit: I haven't played much this month, but climbing with this deck was surprisingly easy from low gold to diamond, I only lost like 2-3 matches at plat 1, but that's all. When I made it I thought it was just a bad fun deck, but it is actually really decent and has a ton of good matchups on the ladder. You are favored against most aggro decks (you are faster then them, maybe a highrolling Aggro DH or Pirate Warrior can keep up with your speed) and honestly control decks weren't a problem either, they usually don't have enough early removal/AoE and you overwhelm them pretty quickly. I don't have much data cause the climb was so fast, but Secret Mage (or other kinds of Mages) can be hard to beat with their freezes,Ice Blocks and high burst potential even at early stages of the game.
All in all, extremely fun and surprisingly solid deck with a unique playstyle, if you have the cards, definitely try it out!

Gamplan:

1. Mulligan for 1 drops and Darkglare. You can keep 2-3-cost cards if you already have a decent curve if you feel like. Flame Imp, Kobold and Ashtongue are the best starters, Crystallizer is better in the midgame, more about this later.
2. Get board control and get ahead on tempo. Your minions are usually overstated so it should be fine.
3. Try to set up combos with Darkglare, Diseased Vulture and Nethersoul Buster around turn 4-7. These combos became much easier with Darkglare and the mana cheat, you can make explosive things really early in the game (see the pictures below). Plan ahead 2-3 turns, but don't get too greedy, it is easy to mess up with this deck so be patient and don't rush your turns. (Important: Darkglare can only refresh your mana, it can't generate more mana than your actual mana cap.)
4. Drop the Giants and the Reavers in the midgame.
5. Use the fully upgraded spellstones (they are always fully upgraded when you play this deck) and the Spirit Bombs to clear your opponents minions and close out the game with your minions ASAP. You don't have burst so you have to control the board.

With this deck you want to be at 10-15 health, this may feel odd or scary, but that's how the deck works. The perfect scenario is when you are at 10 hp and 5 armor, so try to use your other self-damage cards before you play Crystallizer and stabilize your health with that.

This deck is really fun and actually pretty skill-intensive. Your opponent makes a mistake, he is dead. You  make a mistake, you are dead. The games are also quite short so if you want a really aggressive, but not brain dead deck which is fun to play, you should try this.

Don't craft any card for this deck, this is a fun deck, try to replace things, get creative etc. 
Here is the link to the old version of this deck where I talked about some of the possible cards for this deck: https://outof.cards/hearthstone/decks/6106-sou-suicide-warlock-20-7-wl
(I cut Chittering Tunneler and Voidwalker for the new cards. Maybe Voidwalker should replace a Sunfury, you can try it, really solid card and protects you important minions.
Edit: I put back 2 Voidwalkers and only run 1 Nethersoul Buster and 1 Sunfury Protector)
