I hate machine gun derp priests soooo much. They literally always have raza by turn 5, or 4 with coin, dragonfire pot when it's perfect, and randuin by turn 8. And then kazakus pot comes to save the game if all else fails.
Forces me to play my mindbreaker + nerubian unraveler buff deck to block the hero power and greatly limit the spell choices. Works suprisingly well, especially if I bait out shadow words and pots, and play taunts before those main cards. It's also so funny against jade druids, as they can't even use ultimate lul with nerubian on board, protected by taunts.
