Provoked by the article, I tried to make a Warlock deck and spotted the synergy between Duke of Below and Bat Mask. This deck relies on your opponent not having removal that can deal with that combo. Fortunately, a lot of classes don't as a lot of removal is damage-based now. Unfortunately, that's not every class. The deck doesn't have much going for it in terms of power but it has a few pairs that I would like to highlight and talk about.
Gemstone Hoarder normally is nothing spectacular, but it has a few extra quirks in this deck that make it special. Targeting Naralex lets you play Ysera on turn 7. Targeting Disposable Acolytes lets you get its effect without "using it up" as fodder for your Ocular Occultist. Targeting Mask and Duke lets you pull off the combo without Ysera. Finally, something this list doesn't do but it is possible, you can Mask your Hoarder to get up to 7 copies of a card (like Agamaggan). You could also run Earthen Drake to target with Mask.
The discard package forms an alright early game while also buffing your Duke of Below. Duke is also fine without Mask sometimes. You only need to discard 3 cards for it to deal with a Slitherdrake for example. It also works well with most Dark Gifts.
Like I said earlier, this deck is surely not good — I'm barely positive — but it's quite satisfying and funny when it works, so please entertain the idea.
edit: i forgot to post the code
