I disagree with double Faceless Manipulator, 2 is too many in my experience, for a while, I didn't run any because it was too slow against aggro decks and was pretty much a dead card in my hand, since aggro has somewhat died down, I run a single Faceless now.

I don't own Leeroy Jenkins tho and wish I did, tho I've been playing handlock fine without him
I run Lord Jaraxxus who serves as a good finisher and is great for those longer games such as control vs control and games when your opponent tries to burst you down over 2 turns 

Running Sylvanas Windrunner is also very viable too, it forces removal cards that could be better used on a giant or Twilight Drake
sacrificing your own Sylvanas Windrunner with Power Overwhelming and taking a big enemy minion is very satisfying and can open up nice plays and favourable trades, same goes for Shadowflame and Sylvanas Windrunner

I also run a single Shadow Bolt and Bloodmage Thalnos
Bloodmage Thalnos provides some much needed spell power plus card draw is nice, 2 damageMortal Coil, 5 damage Soulfire, 4 damageHellfire <---- Spell power helps out so much
the spell power boost is amazing to have and wins me games occasionaly
having a single Shadow Bolt has proven useful, sometimes not discarding a card is preferred or acts as 3rd answer if you haven't drawn Soulfire in hand,
I find that Shadow Bolt also help in mirror, Shadow Bolt coupled with Soulfire acts as another removal option for an enemy giant

Am currently running double Hellfire and single Shadowflame instead of vice versa
Shadowflame on anAncient Watcher kills a stealthed Gadgetzan Auctioneer but honestly I haven't seen many miracle rogues around, and sometimes it's hard to set up a turn where you can successfully Shadowflame

Used to only play a  single Twilight Drake too because of the high amount of shamans before tho having a 2nd one is great in other match ups, and better overall, (plus, you might get lucky sometimes and shaman might not draw Earth Shock) 

I'd obviously use Leeroy Jenkins if I had him but my handlock deck has been performing well without him, went from rank 14 to rank 9 and only lost once (to some bs Rng), and I've reached rank 5 twice with this deck, then hadn't bothered to play any further

Leeroy Jenkins is used as burst and finisher, if you're looking for a replacement that fills the same role as Leeroy Jenkins, then your best option is Arcane Golem (I don't run this)

 other good replacements include Sludge Belcher,Sunwalker, Sylvanas Windrunner, Ragnaros the Firelord, The Black Knight, Loatheb

it depends on what you need and what you feel is best against the decks you play against, so it's hard to say 1 particular card that i used to replace Leeroy Jenkins as it always changes for me

but I recommend using Sludge Belcher or Sunwalker 

hoped that helped a bit :)

Great deck, and relatively cheap too, thanks to the current meta. Although I run two hellfires and actually have two sunwalkers in mine, which sort of helps me not getting overwhelmed by zoo. 

Thank you! :) And I often switch between 2x hellfire or 2x shadowflame. Kolento actually runs a deck similar to this with both 2x shadowflames and 2x hellfires but minus one faceless manipulator. What do you run the two sunwalkers for?

I dropped BGH because 80% it lied dead in my hand. SS seems more than enough for the biggies, and if push comes to shove, you can trade giants. Although this season I don't play much and still linger between ranks 8-6, so maybe it'll be different on higher ranks. I also only run 1 facemanip, so that's two free spots it the deck. Alexstraza is too slow, so I wasn't quite sure, what to add. But then time and time again I found myself on turn 7 with cards like leeroy, different removals and sunfury/argus, so, essentially, nothing efficient to play. So it really felt like i need another creature. Sunwalkers are quite difficult to deal with, and it's an additional taunt, so overall, I'm really digging them at this point.

I'm very interested in trying handlock, but I have a question. Would Pit Lord work with this deck? Seems like he would be a great turn 4 play (or turn 3 with coin), or even a great minion to drop a turn before Lord Jaraxxus or Alexstrasza. In an ideal situation, you could even drop a Pit Lord to get you down to 12 (or less) health on turn 8, along with 2 inexpensive Molten Giants followed by a legendary on turn 9 to bump yourself back up to 15. I understand that you would *really* need a taunt to go with it if you wanted to survive against an opponent's board, but I still think it could work. Am I crazy, or would you just consider this a "win more" type play? I know Pit Lords aren't supposed to be very good in ranked play, but it seems to me like this deck might be one of the few where you could get away with (and possibly even benefit from) the 5 damage to your face.

In theory that works, but the problem is so many decks focus on bursting you down that you will not have enough time/health to do that. You can pull your combo off of dropping the Pit Lord and the molten giants but get bursted down by spells (or sap/leeroy step combo from miracle rogues). I've had problems trying to survive as warlock just because the burst(of decks like druid, fon+savage roar, rogue leeroy+shadowstep is so strong against it. It seems like you cant survive even being below 20 health in this meta.

But aside from all that, try it! I think it sounds like a good idea. Pit Lord isn't a card that I really like but your theory crafting makes sense. Good luck.

I got to rank 4 with this deck and I found Jaraxxus too slow, most of the games end by turn 8, hence too slow for what it does. It is AMAZING for control matches but thats it. 
I'm using Twilight Drakes, terrible against shaman, but better over all. Silence is not as common as you can imagine (mirror match and druid mostly, but we already have a good match vs druid). 

The worst match up I is miracle rogue, what a nightmare. I'm considering a second Shadowflame just for that but still wouldn't help much without something to use it on IN TIME.

I think a second Shadowflame is better then 2 Hellfires as Synab suggested here in the comments. I'm really glad you got to rank 4 :).

What did you replace Jaraxxus with? Did you still run Alex? I'd love to see your deck list.

And Yes, I just happen to really dread Twilight Drakes in the shaman match up, maybe I am paranoid. (Was going against a ton of shamans when i initially wrote the guide so you can see where my frustration stemmed from) I really like the yeti I guess. I think having twilight forces you to keep your hand full which can be restricting. But I do see how Twilight can be very strong.

As for miracle, with my experience at least (Playing this deck a little lower then you around the 9-7 mark) You just have to be more aggressive. The turn 4 mountain giant is not viable against miracle decks if you can get an ancient watcher out and silence it to start pounding their face early game. Or at least that's what I've seen in my game-play. Maybe you have a different opinion about it? 
And thanks for the insightful comment, again I'm glad you were able to get to rank 4 with this! Good job!

Don't take my word for granted, I don't always make the right choices. I still suck at this game but this deck took me straight to rank 6 without any loss. After that I had to tweak it for ranks 5 to 3, handlock is very hated here. LOTS of Big Game Hunters, even from classes that don't need them. At some point on saturday I had to switch to Druid because I was facing shaman every 1 out of 3 games.

I don't play either Jar nor Alex, too slow, I tend to end games by turn 8 (win or lose). I'm currently testing Sylvanas , decent results so far. If she gets hex/silenced means one less silence on a taunted giant or drake (which could cost you the game). The whole idea of "omg, I don't want sylvanas to steal my minions, must sacrifice them all into her" is a thing I love to see, they should just ignore it and develope/deal more damage instead but the silly guys won't learn :D
She also works as a pseudo mind control if done right. 

I have never been dissapointed from Hellfire nor Shadowflame, I would use 2 of each if I had more space.

Hmm interesting, would you mind posting a deck list? I'm very interested in seeing what you're running. I may try it myself. I am running Sylvanas Windrunner in some other decks and can definitely agree people have a "Sylvanas Syndrome" haha.

It is very OTK based, a friend gave me the idea. It works very well againts miracle rogue [I guess I exaggerated this match up, but I've been so unlucky with them] and other rushy decks. 
You can change 1 power and 1 faceless for Sylvanas Windrunner and something else, like Bloodmage Thalnos, Shadowflame.

 

Nice, I like it. I just got to rank 5 playing zoo and decided to switch it up and run something like this. The only difference is I'm using a black knight instead of a faceless. Honestly making me rethink jaraxxus as a whole haha.

You don't really need black knight, you will mostly use it vs druid and we already have good matchup against them. If you want it vs mirror, BGH is way cheaper for the cost. 

I'm stuck at rank 4 and half with my sylvanas version, I will test with the bursty version [2 faceless, 2 poweroverwhelming]. 
I don't have thalnos, but I think it could be good. 

What's your battle tag? I'm at about rank 5 right now running into all sorts of random things haha.

You're right, Hellfire handicaps a bit too much. One may be just enough. I'll try playing with 2 shadowflames and get back to you.

I still run two of them, just so i have more chance of drawing one when i need it.

Whats the game play of this deck sorry im a newbie

I'll add a section about that but generally for the first few turns you want to tap up and get cards. Actual turn 1 through turn 4 plays vary based on your mulligan. But getting a turn 4 mountain giant is a consistent strategy that has worked for me, it forces your enemy to dump a lot of cards into removing an early 8/8.

or you try and drop a yeti/twilight drake by turn 4 so they waste cards on them.
