We have a VERY HARD Co-op tavern brawl this week, where you are at the mercy of your opponent to play optimally to kill the 95 hp Mechazod.
TIPS: 1. Favour healing the druid slightly as he has a zombie chow to heal you 2. Save Millhouse manastorm for a later turn where your opponent has a lot of spells and mana to play them. Similar to lorewalker cho where you want to play him later to maximise value.
3. DRUID MULLIGAN AND PRIORITISE RAMP and Mage prioritise card draw early!
4. NEVER have more than 6 minions on your side as mechazod will destroy them all.
5. Get a wide board of 6 for savage roar.
6. Generally you dont want to waste minions on mechzod as they are more valuable as diversions for his "use attack damage on 3 random enemies" and the more minions the less likely a face is hit.
Hope that helps!
