Well, hard to say out of Shaman or the Hudsons who'll be the happy one holding things together on the dead side. Living side I'd say Sasquatch or Snowbird.
So if the 'devil' is the Great Beasts, Shaman won't be happy about being alive, and Snowbird won't. Sasquatch will have to hold the living team together. Heather/Mac will be happy to be alive and keep the 'dead' in it.
Remember, he said they fight on 3 fronts, maybe Puck in Hell, Sasquatch, Guardian, Vindicator, and Marrina fighting the Chaos King minions, Snowbird, Shaman and the twins fighting the Great Beasts.
