19 points left over. Here is my list I am planning to start practicing with. After much help from you guys I have narrowed it down to this. Here are a couple thoughts I have on it...
-I know the more "competitive" core choice is to run Bloodletters however with the way my list is I think Siren Song + Nettes provide something my list is missing. I only have 2 real fast Warmachine/Mage in the Fiends. SS + Nettes lets me pull things around and out of position to try to make up for that.
-I've never used a GUO before but from all the greater daemon suggestions and help I've gotten it seems to be the most competitive choice. Going to try it out for a couple test games and hope he fills that other hole in my army like others suggested he did

-I'm kind of scared with just having 1 HoT however my second + 2 Flamers needed to be dropped for room for the GUO + Fiends.
What are you guys thoughts on the list? Anything that stands out that you would suggest changed before I start testing next week? Any idea on what to do with the extra 19 points lol..
Thanks!
