Are you looking to play a new twist on an old deck archetype? Zoo Warlock is an archetype that has been around ever since the beginning of Hearthstone and has seen play in many different forms, even in the Wild format. Zoo warlock was outclassed by other aggressive decks ever since the release of Patches and the existence of pirate warrior. With the recent nerfs to Innervate and Fiery War Axe (which saw play in aggro druid and pirate warrior respectively), Zoo Warlock now has more of a fighting chance or even favorable against other aggressive decks. In this article, I will discuss the Demon Zoo archetype, a subarchetype that aims to exploit the power of demon synergy cards like Voidcaller, Mal'Ganis, and Bloodreaver Gul'dan.
