This Reno Jackson deck is very powerful because of the clearing and lasting power.
Greater Healing Potion gives you more lasting power when your opponent can burst you down next turn.
Kazakus is combo of both of the above. Craft a 10 mana spell and try and go for Gain 10 Armor ( Stonescale Oil ) and Deal 6 Damage to All minions ( Felbloom ). This will keep you alive and remove aggro Shamans and Jade boards.
Deathwing is the topper against boards that will be filling with buffed minions from Warrior and Paladin and Jade decks.
