Hearthpwn

Lakkari Sacrifice: This is the quest that the deck revolves around

Malchezaar's Imp: Very important to the deck because it allows you to refill your hand after you've discarded cards.

Soulfire: Great for burst damage and removal, also adds another discard for the quest.

Clutchmother Zavas: This is a great card for this deck because it gets buffed after every discard and also is an endless discard.

Corrupting Mist: This card could rotate out of the deck, however, I think it is important for controlling the early game against aggro.

Darkshire Librarian: This card is great because it has discards for the quest and card draw for the rest of the game, also the deck needed a strong 2 drop to implement.

Bloodfury Potion: This card is great for two reasons, buffing the attack of smaller minions for trades or a shadow flame, or buffing a large demon for board control.

Sense Demons: This card is probably gawked and laughed at however I believe it is strong in this deck for two reasons. It allows you either to draw Malchezaar's Imp, Doomguard, or Lakkari Felhound all important cards for the deck. And number two, for the memes, the memes bro.

Shadow Bolt: Great for minion removal and could change out for another card but I think it's a strong tool for early board control.

Silverware Golem: Great synergy with everything in the deck and rewards you for a discard.

Crystalweaver: Great in this deck because it buffs the already strong demons, and because of its good stats is still not bad to play on board without any demons.

Lakkari Felhound: This card is really good in this deck for a few reasons, great stat line, discards for the quest, and can be buffed by all demon things.

Shadowflame: This card could arguably be replaced with a better option, however, I think the attack increase with Bloodfury Potion and the already big minions give this card a lot of value.

Doomguard: Awesome card, discards get more value, and great stat line, charge allows for value trades as well.

Felfire Potion: This card could be replaced but I think it will help with overwhelming situations

Kabal Trafficker: This is a great card in the deck because it is a strong six drop which generates either more possible cards to discard or more demons to buff.

Siphon Soul: Good removal for those pesky quest rewards / big minions

Fire Fly: Good one drop and creates a discard, could be removed but I think it's a good addition

Cult Apothecary: Fills two needs, healing and a five drop

Deathwing: Good for a desperate situation or just straight up finishing you quest instantly.
