I've been rearranging my list a lot lately (bored at school with no models to work on :( ) and I can't quite settle on the version I like the most right now. So, I'll post the core of the army (that I would prefer not to make major changes to) and then post some of the ideas I have for using the rest of the points. I'm also open to completely new ideas, and the only thing I won't really do is run a Defiler (I hate the model and want nothing to do with it). Here is the core:
Demon Prince: Mark of Slaanesh, Lash of Submission, Wings
155
Demon Prince: Mark of Slaanesh, Lash of Submission, Wings
155
7x Plague Marines: 2x Melta Gun, Personal Icon, 1x Champion: Power Fist
+Rhino
261
7x Plague Marines: 2x Melta Gun, Personal Icon, 1x Champion: Power Fist
+Rhino
261
7x Plague Marines: 2x Melta Gun, Personal Icon, 1x Champion: Power Fist
+Rhino
261
3x Obliterators
225
3x Obliterators
225
TOTAL: 1543
Depending on the options, I'm compeltely open and willing to drop things like Rhinos, Icons, Wings, etc to make some saucy looking units fit, so I have anywhere between 307-400 points to spend. Right now I'm leaning towards this for the rest of the points, if I drop a Rhino it fits perfect points wise:
Greater Daemon
100
Land Raider: Daemonic Possession
240
I like it because it gives me something that cna actually fight and kill things in close combat aside from the Princes. The
GD is just a beast and is fantastic for cleanup duty if anything lives through the standard lash together and plasma cannon routine. the Land Raider gives me a rolling fortress to stash a scoring unit in (
PMs are very resilient, but it increases a ton with the
LR making them so hard to remove its silly) as well as something that can hide a Daemon Prince completely, so its like a moving piece of terrain to help cut down the fire coming towards them. It also brings a cuple more Lascannons for mechanized lists (though 6 from the Oblits might already be enough) and things like scary
MCs. At this point, I get really worried about how tiny the army is though. It'll total a mere 34 models (yikes!). I would probably be switching some assault weapons over to Flamers at that point because that is just not enough to deal with horde style armies. I also really like this one:
Greater Daemon: 100
Dreadnought: 2x
DCCW, Heavy Flamer, Extra Armor
115
Dreadnought: 2x
DCCW, Heavy Flamer, Extra Armor
115
I get some very solid
CC ability here. If some combination of the
GD and Dreads charge the same thing it should be more or less dead. Dreads with 4 attacks each (5 on the charge) are just nutty. They hit almost as hard as the
GD does! They are perhaps not as survivable as the
GD though, and I don't get a Land Raider or other tank but I suppose the
DPs fit behind the Dreadnoughts pretty well for at least a cover safe.
Other options include:
307pts worth of Terminators in wahtever equipment seems awesome (Chainfists, combi meltas and combiflamers aplenty

). This seems neat as I can do a bunch of things with them like run small units that function similar to Tau Crisis Suits with Fusion Guns. Units of 3 Termies with combimeltas are 105pts each and are great for deepstiking next to scary opposing armor.
Drop icons and maybe wings to get a few termies and a Land Raider. This option has appealed to me for a while, but when it comes to it the Greater Daemon just seems so much more scary and for less points than a bunch of termies.
Vindicator and a small unit of chosen (3x Flamer, 2x Melta) in a rhino. I like this one because the Vindicator is nasty with Lash spam, but the Chosen don't seem to really do anything cool for me that the army doesn't already do well. Mostly it seems like more of the same.
anyone have thoughts or ideas for how to fill the remaining points?
