Came back after a long time away since some of the new cards looked like fun, playing around a lot with control warlock, feels a bit janky and im probably not playing it properly.
I based my list off the one here previously, and some deck some guy used to get high legend with.
Some problems:
Whether to include giants and drakes or not: I feel like the deck is definitely stronger with them in, quite a few games were complete steamrolls on my side and when climbing its nice to have that potential instead of every game being a long drawn out game, and with the aggro removal cards I don't get run over too hard and I feel like its stronger than trying more of a tempo based start though the healing from the 1 drop guys would be nice.
Hellfires x2: I just can't seem to find hellfires useful ever. I also found this in original handlock, its just so expensive to play both in terms of life and mana, and often the board would be refilled insantly and I had gained absolutely nothing except lose a lot of health, it never seemed to gave me the upper hand. Right now Im experimenting just using one.
Doomsayer: I find it hard to get value from it also, again a lot of time its a dead card for me (maybe Im just playing it all wrong). Again trying with just one.
My main problem with the deck was that I was finding that by the time I got to midrange with the deck itself I was getting outvalued by quite a bit by many of the decks I was facing. the 6 mana infernals arent that great, the abyssal enforcers would bring me quite low, or any board I had low, and I had to play at least some of these to make guldan have somewhat of an impact (though he does feel quite low impact to me still). I tried the variants with Lich King but the cards I got were total duds and he always got removed very quickly, and there would be this time where LK was dead, I didn't have many cards to play from guldan, my opponents board needed cleared but he had the potential to refill, and if I played guldan his impact was quite low with his 10 mana cost.
Basically Ive settled on this list atm:
Its a bit all over the place, but I tried to take out some of the more excessive board clears, i think it fares quite well midgame now. Eater of secrets is tech for mages because I faced so many today and its probably just a rage-pick to piss them off, can be swapped for druid tech card when necessary. Black Knight getting really good value from the 7 mana give minion taunt+stats card that a lot of my opponents run, from killing stegs, lich king etc. Alexstraza is an experiment of trying one less hellfire to give me some heals or some offensive game closing power before guldan drops. Ysera is a sub for lich king to actually give some good value at that point in the game, and its helped a lot against the priest decks/late game.
All in all im not sure how I feel about gul'dan yet.
