Trying to work up an all comers 500 point list, and stay fluffy. The main armies that will be faced are Ork, Space Marines, Necrons, Tau, and Tyranids. Here is what I have came up with so far.

Daemon Prince
Mark of Slaanesh
Lash of Submission

Emperor's Children (6)
Sonic blaster (2)
Blastmaster (1)

Emperor's Children (6)
Sonic blaster (3)
Blastmaster (1)

Comes to 500 points exact.

The strategy if to keep them pinned, and to staying 20+ inches away. The prince moving to pull in firing lines armies, or if CC gets too close to move them so not in assault range. Will also help bust any armour, if the opponent takes it, and the blastmasters can kill it. Though I plan to keep it in range of the troops incase of outflanking. to move the flankers out of assault range.

Any comments and criticism is appreciated Thanks
