Ok trying to expand on my Nurgle army.

[Xaric]

Ok so I want to take a allied detachment of CSM Using cultists with mark of nurgle as my ranged unit with a daemon prince of nurgle with wings but what else to add? Has to be nurgle themed plague marines are a option. But I need some more advice on people who have more information about the fluff of nurgle to find units that could be acceptable.

Chaos bikers would be good having T6 same as Chaos Spawn Could get some havocs T5 making them almost immune to S9 weapons.

Could i use the space marines from the DV starter set as Chosen.
