Looks good at 1500pts. Lots of units. Fast and furious.
A couple of alternatives:
Your Archons equipment is a bit of waste. Soultrap doesn't work really. Best use of him is with Blaster, Agonizer, Shadowfield and Webway Portal. But get pricey at that point. I like running him with just a Blaster. Cheap and dirty
I'd get Night Shields on your Raiders, they will Jink a lot and it makes a big difference with 3+
I like my scourge units a bit larger. And with Blasters. Hayewires just dont seem to do enough for me. I like that a Blaster can blow up something with a single shot and you can stay 18" away still... Try 8 man Scourges with 4 Blasters and a Solarite for LD. Incubi are fun but not that great at few numbers - Minimum 5 is needed. Preferrably more if you can find the points.
I would portal down a Raider with the Archon and either 5-6 Trueborn with Blasters and a Blast Pistol or a unit of 9 Warriors with Splinter Racks. The Trueborn unit is nice. 6 Blaster shot and a Dark Lance shot from a Raider with blow up most things!
This just making the list more effective maybe not more fun to play... Except the Webway Portal. It's fun and very useful.
