FWIW, I usually go to like rank 15 and am not great at this game, but maybe something to start with.
Heres my control lock deck. I recently cut a doom but that might be an ok substitute for 2nd nether. Would definitely add it back if meta goes all 10 drop again. Shadow flame is not the best global when you are not running power overwhelming, as this list has many fat buts and 4 mana + creature for 2-3 damage is not comparable to trade into spreading. Sacking 'can you hear his calllll' sucks as obviously as well. Hopefully earth ring hits beaconer or void after they have 1/2 traded, but he is great healing to the face as well, many times I will have two or combo with portal on turn 6 for portal+2 earth ring. Voodoo doctor wasn't as good for a lot of reasons. I bet there is probably a better 1 drop than flame imp somewhere.
If I had starseeker I would definitely run her, so i suspect a reno version would work. I could not fit a dreadstead as that card does not provide enough board presense against aggro, even though it is quite clutch against mage comboaggro.
The real star is the usher ritual combo and you should definitely run ritual in cthun warlock. If you are playing 2nd, situationally it is often correct to play ritual on turns 1-3 for even 1 mana on turn 3. Once you see you are against zoo lock you should just use it a mana sync immediately as the 1 mana bodies like villager, ritual, imp void are the only way to survive this meta. If you can keep enough board control that trades + 2-3 damage will wipe the board then your midgame can dominate them.
You crush the mirror unless a lot of bad **** happens or they mana ramp faster and cthun you. You ritual into usher. You portal into cthun. You have much early drops strong midgame and just need to hope cthun isn't on the bottom of the deck if they stabilize. Pyroblast is a v bad matchup but for a cthun list this is probably as good as it will get. Use ritual as a tempo play and try to keep his weak ass creature off the board. Always heal to the face and dont hero power. Arch mage is a gg every time unless you are way ahead on the board.
Feedback very welcome.
