While the poster above me has a point, i have a list which can hit kind of hard.
Be warned however, that stuff like FEC will still eat you alive before you can get a single attack out...
List goes as follows:
Blight Cyst:
Lord of Blights
4x 5 Blight kings
Harbinger of decay
The Glottkin
Pusgoyle blightlords
This will get you at 1760pts, so you can add some more Blightlords, a second caster, more blightkings , whatever you want/have.
The blightkings can do massive damage, buffed by the Glottkin's extra attack from his CA and the Harbinger will keep them alive a bit longer.
With the Nurgle wheel and trees you dont even have to be very slow.
Hope this gets you started
