The Plaguebearers and Nurglings will tie enemy troops up, while the Great Unclean Ones, Daemon Princes, and the Beasts of Nurgle will destroy enemy Characters; and the Soul Grinder will take out Heavies. The only problem is that I have a lot of points left, and I don't know where to put them. Please, reply with any options.
Note: I want to keep it PURE so if its possible where should I look.

Thanks in advance!

I love Nurgle and all of its fluff, so I want to put my two cents in... There is a lot of commotion now regarding the release of the 5th edition. One of the topics are that only troop choices will be scoring units. With only 3 troop choices you might be in trouble. (thought other units can contest)

Another thing is speed. You have a fairly slow army, and even though you are DS in your whole army, you might suffer from that.

Why are you using two great unclean once?
