Due to the lack of responses for my first list, I'm assuming it's either a turd or it's perfect. I tried it out a couple times and wasn't a real big fan. As a result of that, I tried a bunch of new lists. After walking down that road, here's what I'm currently looking at:
CSM - Primary
Daemon Prince - 275
Tz, Black Mace, Wings, Armour, Gift of Mutation
Daemon Prince - 265
Khorne, Blinding Axe, Wings, Armour, Gift of Mutation
Cultist @10 - 50
Cultist @10 - 50
Heldrake w/BF - 170
Heldrake w/BF - 170
Daemons - Secondary
Keeper of Secrets -225
Exhaulted Reward, ML x2
Horrors @16 - 144
Horrors @16 - 144
Daemon Prince - 255
Slaanesh, 2xGR, Wings, Armour
Defense Line - 100
Quad Gun
This comes in at 1848 and should be fast playing, but still have some shooting. Skipping a phase wasn't working out very well for me.
Here's the plan: Take the portal glyph on the Keeper and let it gin out Horrors to throw at the opponent. Then sit the Keeper on the defense line to shoot that quad gun. Drop the units of horrors back there with the Keeper and have them shoot it up and shamble forward if the opponent tries to keep 24" away. The cultist are pure objective holders to be put behind the defense line.
The two CSM Princes are to push forward and whomp with. The khorne one is better against armour, while the tzeetnch one is an infantry slayer. The black mace is one of the most filthy weapons in the game. The last DP is more of the swiss army knife. It can take the lash to hit flyers, or tool up to fight in hand to hand. Finally, the heldrakes just come on and burn infantry down. I'm still torn on whether to run two flamers on them or put the cannon on one. The low BS is just a killer on the cannon.
I'm going to give this a try this week and think it will fair pretty well. I still feel like I might need a soul grinder and a Nurgle Daemon Prince, but you just can't have it all. What are others thoughts?
