Certainly not the best DE 1500 army, and I'm worried about anti-tank - here's hoping there's a lot of footsloggers - but it has a lot of units that I like both fluff wise and aesthetically so that makes me happy, and will motivate me to paint it. I'm wondering, should I drop the hekatrix with the venom blade to stick haywires with them? haywires are totally win these days.

I would also like a couple more incubi and perhaps an onslaught klaivex, but I suppose I still have 7 skimmers and 2 flyers that can really put the hurt on infantry so the incubi's job is basically to mess up marine troops units that get caught in the open. 6 is not usually enough to go right through a marine squad (they kill 1 marine each statistically on the charge) but enough that they are a pain that need dealt with

Also, dunno if i should mix razors and voidravens, or just take 2 of one or the other
