Funny that you posted this thread. Yesterday I played probably my last 7th edition game with my DE.
Here is my list :
Realspace Raiders 2000 points
HQ
Yvraine
Lelith
ELITE
5 Incubi with klaivex in an aethersail raider
5 Mandrakes
Troops
2 x 5 Kabalites with blaster in a Venom
8 Wyches with power sword on the champ in an aethersail raider
8 Wyches with agonizer on the champ in a aethersail raider
Fast
Razorwing Jetfighter
10 Khymera + Beastmaster
3 Clawed Fiends + Beastmaster
5 Scourges with Haywire
6 Reavers with heat lances and caltrops
Heavy
Ravager with lances
Ravager with Dissis
It was great fun. I won the game against Emperors children. Yvraine was insane with cleansing flame in the middle of a chaos horde, as was her instant death sword against 4+ or even 3+ FNP. Lelith was a true champion of the arenas, she killed two of bravest souls in the galaxy (cultist champion
), a noise marine sarge, and finally a chaos warlord.
