Well hey there all. Getting into my daemons now, so I decided to write up the list I have put together, to get it looked over, and why I picked what I did. Here goes.
HQ Epidemius (Tally tally tally, my gosh I love my tally)
Great Unclean one with flies, breath, and aura of decay. (Kugath costs too much, for a super-tough suicide attacker, which Is what I use this guy as.)
Troops
10 Plaguebearers with instrument (Instrument actually works really well with these guy's, who often draw with standard infantry)
10 Plaguebearers with instrument (Dejavu)
9 Nurgling bases (Basically joined with Epidemius, to give him an extra wound per 4 points spent

)
9 more Nurgling bases (For wave 2, when the tally is high, these things kill -anything- that isn't a vehicle, heavy hitters sent in first to crack open vehicles, then nurglings to gobble up the peeps inside ;D )
9 More MORE nurgling bases (These things are so damn cheap, that it's just worth taking this many, even if epidemius dies.)
Elites:
6 Flamers of Tzeentch (Painted up as "Bile-spewers", these are literally just for cracking open vehicles my standard units can't, or softening up really scary infantry)
4 Beasts of Nurgle (Yes, I know people say they suck, but honestly, these things actually lawnmower most anything, and when the tally is up, my good god. xD)
4 Beasts of Nurgle
Heavy support
1 Nurgle Daemon prince, breath, aura of decay, flies. (These things die -way- too fast for my liking, so I have taken only one, to try and rush me some tally turn 1 with my unclean one.
So, I use them like this.
(Hopefully) First wave
Epidemius with nurgling bodyguards (To hide away somewhere)
Great unclean one (Wreak big things early)
Daemon prince (Same as avove)
4 Beasts of Nurgle
6 Flamers of Tzeentch
Wave 2
10 Plaguebearers
10 Plaguebearers
4 beasts
9 Nurgling bases
9 Nurgling bases
Deepstriking, monsters, swarms, and a plaguetally. Lovely.
Not as much "Huge and scary" as most daemons list, but it can really chew up some armies. Only weakness I have found, is that I really cannot hurt flyer's in the air, at all. But, hey, Nurgle unit's can just grin and bear it, get into assault to stop being shot at.
And who need's fast attack units, when you can deepstrike and spread across the whole area
