Woah! Such insane feedback! Since I have uploaded this deck I've been grinding to reach my new personal best rank, Rank 5. It took a while, but I managed to push through.

You may have noticed I dropped two Darkshire Librarians for a Argent Squire and a Succubus. This is because, as some of the comments suggested, too many discard mechanic cards can be quite hazardous so by adding these cards the deck becomes a little more consistent and you also get an extra demon for Bloodfury Potion and Demonfire

First off I'll start by telling you why Demonfire and Bloodfury Potion are in the deck because I know its a little odd. And the reason why they're in the deck is because if you are going against Pirate Warrior you could end up with a Voidwalker on turn one and be able to curve out and buff it by +2/+2 to increase survivablity against Fiery War Axe and Small-Time Buccaneer. It also works as a great early game small minion removal. As for Bloodfury Potion it is just an excellent buff to help kill Ancient of War and both just work great on Imp Gang Boss.

THE MULLIGAN & STRATEGY

Jade Druid

Against Jade Druid your goal is to gain as much tempo as possible in the shortest amount of time possible. In my experience going second tends to work best due to being able to coin out multiple one drops.

So for the mulligan you are going to want to look for Flame Imp, Voidwalker, Dark Peddler, and of course Imp Gang Boss. Possessed Villager isn't that great of a start against druid but can do work if they useLiving Roots for two Saplings and can kill a 1/1 Jade Golem with ease. Only keep Soulfire if you have Silverware Golem in hand as well.

Miracle/Pirate Rogue

These are by far one of the worst match ups for this deck because of the cheap removal of small minions the Rogue has at their disposal, but if you're lucky you can win.

The mulligan cards you're going to want to look for are Voidwalker, Dark Peddler, Imp Gang Boss, Silverware Golem(only if you have Soulfire in hand), Soulfire (this is for Tomb Pillager), and Malchezaar's Imp.

Pirate Warrior

This match up isn't too terrible as long as you get Voidwalker early and can manage the board along with curving out nicely.

The mulligan cards you're looking for in this match up are Voidwalker, Malchezaar's Imp (this is because it is able to kill Patches the Pirate and Southsea Deckhand with relative ease), Soulfire (this is for a buffed up Bloodsail Raider or a Frothing Berserker), Flame Imp, and Imp Gang Boss.

Aggro Shaman

Believe it or not I haven't run into this deck all that often so I don't know much of what to do against it, just curve out and try to maintain as much tempo as possible.

The mulligan cards probably best for this are Soulfire (for that great card Totem Golem), Flame Imp, Voidwalker, Dark Peddler, and Imp Gang Boss.

All Reno Decks & Dragon Priest

These decks are ones where you have to just destroy their face as quickly as possible in hopes they don't have a board clear or Reno Jackson.

The cards you're going to want most in your mulligan are Flame Imp, Voidwalker, Imp Gang Boss, Dark Peddler, and Possessed Villager
