I put all the cards together into a deck and tried it out.
The first few iterations didn't work. Not enough creatures that could kill the opponent. I kept iterating until I got to this.
To deal damage to your own creatures use:
Pyromancer (this is the best one, try to save it for a good time)
Slam (I basically never use this on my own creatures)
The 2 minions Leeroy makes can trigger enrage and pump your guys.
Your opponent's creatures also deal damage of course.
To benefit from taking damage:
Acolyte of Pain
Commanding Shout + Pyromancer:
This combo can often deal 3-4 damage to all of your opponents creatures while yours all survive because of commanding shout.
If you have a frothing berserker out when all of this goes down he can sometimes be pumped up to 20 power.
If you have an Armorsmith out when this goes down you can sometimes get 5-10 armor from it.
Acolyte of Pain gives you 2 cards and survives to give you one more later. Note that if a creature is at 1 health and Commanding shout is preventing all damage to it then it will not trigger.
2 Battle Rage
2 Commanding Shout
2 Cruel Taskmaster
2 Fiery War Axe
2 Amani Berserker
2 Wild Pyromancer
2 Frothing Berserker
2 Warsong Commander
2 Acolyte of Pain
1 Arathi Weaponsmith
2 Raging Worgen
1 Leeroy Jenkins
2 Gurubashi Berserker
I tried a lot of other cards, there are the ones that I was surprised to cut because I thought they would be great in this deck:
Try it out, it is pretty tricky to play because there are so many cool interactions. Enjoy and let me know how it works out.
Edit: Added Leeroy Jenkins. You have lots of ways to kill his whelps with tremor or pyromancer. You can also attack them with an enrage creature or with Acolyte of Pain for value.
