This is my first go at a CD army list :
1 Bloodthirster 250pts
1 Masque 100pts
1 Herald of Khorne on Juggernaut 105pts

5 Bloodcrushers, Icon of Chaos 225pts
6 Fiends of Slaanesh, Icon of Chaos 205pts
5 Fiends of Slaanesh, 150pts

9 Bloodletters, Icon of Chaos 169pts
9 Bloodletters, 144pts
9 Bloodletters, 144pts

My idea is the Bloodthirster, Masque, Bloodcrushers, Fiends without Icon and Bloodletters with Icon come down first. The Bloodthirster is there as a fire magnet : if it survives great, it can go after Carni's, Land Raiders etc. The Bloodcrushers are hopfully 2nd fire magnet. The Masque is there to firstly push enemy units into less favourable firing positions in the first turn, and in later turns pull them out of cover for the Bloodthirsters to attack. But it seems to me CD are more vulnerable than most to the dice gods, and there's only so much planning can be done

Advice appreciated.
