Hearthpwn

Budget friendly zoo deck without any legendaries and with only two epics in it. Cheap but very competitive deck! I have used this to climb platinum rank this week and it works great.

The biggest difference with this deck from other warlock zoo decks is the inclusion of Faceless Ragers and Midway Maniacs.

Use the Faceless Ragers together with Flesh Giants if possible. They sync really  well with Midway Maniacs as well. Maniac at turn 2 and Faceless Rager at turn 3 and you are set up for victory!

Fire Breather for clearing the board if you face all those pesky druids with their treants.

Use the Raise Dead to get your taunt minions back when you face Rogues. They get incredible annoyed when you keep putting a 1/5 taunt minions in the way of their Self-Sharpening Blade and their stealth minions :)

Mulligan for low cost minions, get early board presence and play as an aggro face deck mainly. With the exception of taking out the occasional extra powerful enemy minion if needed.
