Tip: Dont use your 1/2 flame elementals just to use up the rest of your mana! only use when you haven't played an elemental that turn, or to combo with battle rage and frothering beserker.
Tip: Keep ravenging ghoul in the opening hand vs Hunter or Warrior. also keep servant of kalimos in your hand if you go second because you will often be able to easily play the card on curve. but do not keep it against aggressive decks. This deck losses to quest rogue hard!
Replacements for Grommash: A good replacement for Grommash would be another late game card or burst card such as Leeroy. Grommash is not a key player in the deck. ask me if you don't know what could replace a card that is in this deck.
Update!: swapped fire fly for sleep with she fishes.
I encourage you to also experiment with this deck! you don't have to copy this deck exactly!
