I thought I had a list posted on here, but I appear to be mistaken. Here is a rough version of the last list I used:
Khorne Coven 490
11 Mutants, Daemon Prince, Icon Bearer, Daemonic Pact
7 Chimeras
Khorne Coven 385
Demagogue, Mutants, Icon Bearer, 6 Big Mutants, Daemonic Pact
Khorne Coven 385
As above, except 5 Cultists
Tzeentch Coven 555
Arch Heretic, 2 Mutants, 3 Cultists, 6 Big Mutants, Daemonic Pact, Chaos Altar, 4 extra Cultists
Tzeentch Coven 445
Demagoguse, 5 Cultists, 6 Big Mutants, Daemonic Pact,
2 Hydras
Lord of Battles 400
Khorne Daemonic Assault Engines 300
Khorne Daemonic Assault Engines 300
Tzeentch Doom Wings 150
Traitor Rough Rider Platoon 150
Daemon Pool: 12 Lesser Daemons 240, 2 Greater Daemons 200
Total: 4000
There may be some mistakes, as I've typed it in a hurry, but you get the general idea. As you can see, this list is quite daemon heavy, but it does include Traitor Guard elements, and may well include more in the future, as I felt that the list as a whole lacked fire support. The flexibility of the army is why I like the way it's currently structured on the whole
