Personally i found this the impossible couse i didn't have much od those cards, i build this and it worked really good i did it in 4 to 5 tries, all games had same mechanic, get the [card]Frothing Berserker [/card] buffed, and make him just have 1/1 dishes and be patient.

wasn't so easy for me cause i would get enough for the win with Frothing Berserker but then the Knife comes out and i don't have any more damage to deal, even if i did berserker would only have 1 health and would be killed.

I replaced Cruel Taskmaster with Cleave

Took out Death's Bite for Explosive Sheep

Took out Flame Juggler for Commanding Shout

Eventually i got the win, but it took a while.

i think there are some changes can happen but actually i dont want to work on this deck again.

I don't have Revenge. Is there anything I can do to replace it?

I'm so confused how this was 'easy' for everyone. I'm only missing like 2 cards ( 1 death's bite and an unstable ghoul), replaced with a grim patron and a fierce monkey. But, even in the games I don't draw either of those, it feels like I'm just barely keeping up with the opponent. I never get ahead enough to get any real damage in. I had one game where frothing got up to 12 power, but his health got so low they eventually just suicide'd a plate into it and he was still over 20 health. If I had drawn both protect the kings in a row after getting the frothing that high, it might have worked.. but that seems such a low chance. 

I did finally get it, but it took about a dozen tries and I got almost a perfect draw with frothing and grim patron followed by enough whirlwind effects and taunts.. went all the way to 1 health to do it too. If the computer had drawn another fork at the wrong time, would have lost. 

What should I mulligan for?

any low-cost deal 1 damage like tentacle of nzoth or unstable ghoul

It took a few tries and revisions as I kept stalling out but Protect the king seemed to do the trick with the Frothing berserker out.

i think frothing berserker is the most important card of the deck but in some versions you can play grim patron or protect the king as you say

It worked for me ez win
