I've had two ideas: one with his tier list and one using the pact list.
Tier 1 list:
Bloody barnabas(6*)
Bull Snapper (3)
Ironback Spitter (8)
Gatorman Posse, min unit (6)
Gatorman Posse, min unit (6)
Gatorman Posse, min unit (6)
Gatorman Posse, min unit (6)
Gatorman Posse, min unit (6)
Because Gatomen spam!
Pact list:
Bloody Barnabas(6*)
Blackhide Wratler (9)
Bull Snapper (3)
Gatormen Posse, full unit (9)
Gatormen Posse, full unit (9)
Gatorman Witch Doctor (3)
Gatorman Witch Doctor (3)
Gatorman Witch Doctor (3)
Feralgeist (1)
The idea here is to have the doctors get as safely as possible to the enemy, make something undead and abuse it! Twice.
I'd like some ideas and critiques to improve my lists, so please don't be shy!
