Some cards are tentative;

Commanding Shout

Arathi Weaponsmith

Spellbreaker

Try to mulligan for Fiery War Axe and Amani Berserker/Harvest Golemat start.

Late game is pain in the ass if you don't have your Gurubashi Berserkers and enrages up.

WARSONG COMMANDER!

Always keep Warsong Commanders alive! Because most of your minions have 3 attack and charge is a great opportunity when combined with cards like; Raging Worgen and Gurubashi Berserker.

Use Shattered Sun Cleric, Defender of Argus andInner Rage + Rampage

FINISHER!

Save one of the Inner Rages for Grommash Hellscream. This is a MUST to do if you are playing this deck, else playing grommash and trying to enrage by trading is worthless.

Second option; trust your Gurubashi Berserkers.

Try to have Warsong Commander in your board. Then; drop Grubashi Berserker + an enraged( Inner Rage or Cruel Taskmaster ) + Rampage = Easy 10 damage!

It is also possible to save up for this combo if you have card & board advantage since Warsong Commander is not that deadly itself and your opponent may not be smart enough to remove it.

IMPORTANT

Watch out for board clearers since this deck has 2 guaranteed and 2 situational card drawls. Specially do not have more than 2 minions when fighting vs a mage in his 7th turn.
