The other one is a bit more out there into the dirty territory of soup (But done in a way to squeeze into ITC faction restrictions) consisting of a battalion of Slaaneshi Black Legion (of all the actual traitors they have the most versatility imo given the likely impending nerf to Alpha Legion) including 6 bikes a sorcerer on a steed of slaanesh and a prince, a flawless host supreme command with 3 disco lords and as many goodies as possible (Ultimate confidence, Intoxicating Elixar, Field Commander and either flawless cloak or mechatendrites) and a battalion of Slaanesh daemons with 50 daemonettes; 1x30 2x10 a rapturesss a herald on a steed and syll'esske with a few points left to dot here and there as needed.
Having tried this latter list last night the one take away from it is, the speed is breathtaking. The disco lords are quick, souldforged disco lords are very quick and getting the locus benefit from the herald means they're greased lightning even without Warp Time. Depending on deployment map and where things are dropped, they're easily capable of hitting combat turn one and what they hit will die. Playing against Blood Angels yesterday, the 5 Chainglaive attacks exploded into a further 15 (3 for Ultimate Confidence, 1 for DttFE and one for the Slaanesh locus) between that and the rest 2 impulsors died even with their 4++ which kicked off a further 2 D3 mortal wounds for spirit thief. If you can have the prince and Syll'esske keep pace with them to buff hits and wounds you won't go far wrong because this army will be across the board in the blink of an eye and there's enough nastyness in there to mince screening. I may try and trim down the daemonettes to include something harder hitting like a Scorpius. Bit of fine tuning and I think it'll be a decent list. Needs a lot of practicing though, very finesse type.
+++ I'm glad you had success with it. It is a good match up for that kind of list though too. It gives me hope that I could revisit my 3 Disco Lord list and have some success with it.
My personal issue is I like characters too much. The 3 Disco's cost a lot. I really, really like the Venom Crawlers but if I include them I have no points for other potent stuff. I had been using Oblits, and Masters of Possession to keep them buffed and healed. I really needed a Daemon Prince.
I usually play as Black Legion and take Abaddon a lot which probably hurts me too much. Abe is fun, but slow, and Flawless Host just seems to be the only way I see Disco's played now.
I think Abaddon and 3 Slaaneshi Oblits with a Master of Possesion and a Dark Apostle will be a premier shooting unit, but anyone with an ounce of brain activity will simply hide away anything nasty from them. Abaddon definitely has his uses, just a matter of careful consideration getting the best out of him. Big fearless blobs isn't a bad thing but then that needs some seriously huge hitters to take on big nasties on the opposite side of the table. I didn't find 3 discos too bad points wise tbh, certainly not when compared what they bring to the army. The real issue with them is board layout and keeping all 3 arrayed in such a way that their buffs all overlap and they can all make combat if required.
