I Really LIke the Deck. I played Control Warlock the hole Season and climbed to Rank 5. Now i tried this with 3-2. WInrate. Im not Sure with zilliax yet. Imho in lower ranks, Vulgar Homunculus is a lot better against Odd Rogue. The Geist is very strong against Druidm but also very situational. Godfrey is a Key Player, if you dont have him, do not play this deck. 

what can i swap tunneler with?

I would go for Vulgar Homunculus!

Really fun deck, it's always funny when you get to use Howlfiend well +1. It's nice that it also has room for tech cards that you can switch out depending on what matchups you are getting. I made a video if anyone is interested, had a great game with a Odd Rogue who had pretty much the god hand, thanks.

 While I'm not a control player at heart, this deck is a tonne of fun! Played a few games with it, check them out;

(Games start at 6:11)

While the deck can feel clunky when you're holding reactive cards, the power of those cards in the right situation/match-up is well worth it.

Thanks for chucking the deck up here, I really appreciate it!

what is tunneler 's role???

It buffs your spellstone and you get an extra spell.

if u discover spellstone, does it get buffed? is the order same as kobold librarian where it gets buffed if drawn by it?

I think it should be but have not confirmed it yet.

Yes! I just discovered the Lesser Amethyst Spellstone and it got buffed. 

How i can replace Zilliax? I have all cards exept this legendary. :(

I also don't have Zilliax so I'm currently replacing him with a 2nd Despicable Dreadlord to help against Aggro. I could imagine that a 2nd Demonic Project could be worthwhile if you are facing alot of control decks. You could also run weapon removal (such as Gluttonous Ooze) as the deck doesn't have this.
