Knights of the Frozen Throne has suddenly made the Taunt Druid archetype viable on the ladder. This is the budget version of the deck that is still very potent, and includes the most key card -- Strongshell Scavenger that buffs all of your Taunt minions.
The rest consists of effective early threats and mid-game winners, such as Saronite Chain Gang and Spreading Plague that can fill up your entire board. If you manage to do so, then finish your opponents with the help of Savage Roar, or use it to remove their threats.
It’s a very flexible and easy-to-play deck that can be both offensive and defensive.
