Hearthpwn

"Trash" they called him. "The worst legendary"... "1-star card".. Those words were the only thing on Knuckles mind as he downed another beer in a bar on a mean street in Gadgetzan. Only very rarely had he fought on the battlefields of Hearthstone. But one day he would show them.. Show them they were wrong.. Show them he were not just a meme card. And that day was much closer than he would have ever guessed. 

Knuckles was about to leave the bar, when a courier ran in carrying a message. "The great gods at Blizzard HQ just revealed a new card," shouted the courier for everyone in the bar to hear. "Join the Rumble of Rastakhan and you shall embrace the power of this new card." Then the courier disappeared with a quiet poof. Knuckles  looked out the window towards the Zandalari Empire were Rastakhan ruled and saw it. He saw the new card descending in a blaze of glory. He read the name of it. The Beast Within. As he started to read the effect a wave happiness rolled through his body. He had been given a purpose. He was to join Rastakhan's Rumble and claim the power of this card for himself, so that he could become the lowkey OP legendary, he had always wanted to be.

Alright after that poetic and not at all cringy little prologue, I'll explain what this deck is about. Your gameplan is to buff Knuckles attack, so that you can one-turn-kill your opponent with the help of Leeroy Jenkins for a combo, which deals a total of 31 damage.

It works like this:

Buff Knuckles twice with Smuggler's Crate. Knuckles is the only beast starting in your deck, so this should be rather easy. You then need all pieces of the combo which is: Knuckles, Leeroy Jenkins, 2x Beastial Wrath and 2x The Beast Within. Emperor Thaurissan has to hit 4 of the 6 combo pieces for it to work.

Then when you have the combo you play Leeroy Jenkins and attack the opponents face for 6 damage. Leeroy Jenkins' battlecry is very important, as your opponent has to have some low attack minions on their side of the field which Knuckles can attack when you use The Beast Within on him. It's is not certain that your opponent has minions on the board, when you want to execute the combo, so Leeroy Jenkins makes up for that and adds just enough damage to kill the opponent. The target of The Beast Within only attacks other minions and not the opponents face. (wtf Blizz it's a hunter card) This is why we use Knuckles, so that whenever and opposing minion is attacked, the opponent's face takes damage too.

After playing and attacking with Leeroy Jenkins, you play Knuckles which is buffed up by 2x Smuggler's Crate. Then you use 2x Beastial Wrath on Knuckles, giving him a total of 11 attack. Then you use the first The Beast Within making Knuckles attack an opposing minion and deal 12 damage to the opponents face. You then use the second The Beast Within making Knuckles again attack an opposing minion and deal 13 damage to the opponents face. Considering you attacked face with Leeroy Jenkins, this is a total of 31 damage. Just enough to kill your opponent.

This version of the deck is not optimized but to explain the other card; we run a lot of card draw to reach our combo pieces quicker. Some classes also likes to gain a lot of armor and play a long control game. To counter this we run Deathstalker Rexxar and Alexstraza. We run Master's Call over Stitched Tracker due to the fact that I believe Master's Call draws the card that you discover rather than just giving you a copy. This is much better than the 2/2 body.

Tech Choices could be Harrison Jones if you face a lot of weapons or Saronite Taskmaster to make Big Priest more inconsistent.

Enjoy!
