Here a list that I have been toiling around with for a while now.
1 Daemon Prince @ 200 Pts
Close Combat Weapon; Fearless; Wings; Bolt of Change (x1); Mark of Tzeentch; Warptime (x1)
1 Daemon Prince @ 200 Pts
Close Combat Weapon; Fearless; Wings; Bolt of Change (x1); Mark of Tzeentch; Warptime (x1)
3x 9 Thousand Sons @ 292 Pts
Bolter; Fearless; Slow and Purposeful; Inferno Bolts; Mark of Tzeentch
1 Aspiring Sorceror @ [85] Pts
Bolt Pistol; Force Weapon; Fearless; Inferno Bolts; Warptime; Mark of Tzeentch
3x 1 Obliterators @ 75 Pts
Power Fist
Total Roster Cost: 1501
Should I have my daemon princes with a nurgle mark instead? I would then add a few warriors thousand sons squads to make up the difference in points. Is the t6 really that much of an improvement?
