Lightwell is a great card here, and can hopefully keep you healthy. I found that putting Power Word: Shield on Thaurissan’s Wife is a good way to keep her alive. When going into turn 7 be on the look out for Flamestrike and consider healing yourself over a minion if it won’t get above 4 health. Cabal Shadow Priest and Shadow Word: Pain are great against Imp Gang boss.
