I'm pretty sure the missing Cephalic Carnage from your set is Divination and Volition from Xenosapien.
I'm glad Exhumed did a good job. I had to leave early. I was tired, and I start work at 4:30 in the morning. But I saw them at MDF and I'm going up for this tour today (Friday) in Des Moines, so I'll see them there. Origin was essential for me to see, though, and they did NOT disappoint. Fucking awesome.
