I called this deck Deep Warlock (took the idea from LoR mechanic Deep). 

Not good in English (still studying), sorry about mistakes I could make. : /

DON'T. DON'T BURN your deck if it have Neeru Fireblade. (But not if you are playing against aggro Hunter/Paladin).

MULLIGAN

Always full mulligan for Neeru Fireblade or Taelan Fordring. If you got it, keep Armor Vendor, Loot Hoarder, other 1-4 mana cost cards. Against aggro hunters dont think about Neeru, burn your deck safely. You will win if you survive all the damage. Less cards in your deck = active Blood Shard Bristleback. 

If you play against Control Warlock or Priest keep Educated Elekk to not burn it, it will safe your life later. 

GOOD COMBOS

Mo'arg Artificer + any spell + can be played with Tamsin Roame. 

Spells from Tamsin Roame that cost 0 + Educated Elekk on fatigue.

Also I love when the opponent plays Ogremancer and I play Drain Soul or Soul Shear + Soul Rend. So good and makes you go more deeper in your deck.

Dont run Envoy Rustwix because Taelan Fordring should alwaus give you Neeru Fireblade (x2 chance to find it). I replaced him with Educated Elekk and I'm feeling good (2-3 spells to shuffle is enough). 

I also cut down Barrens Scavenger - they will drop from Taelan Fordring.

Good luck and have fun :)
