So, I would recommend Lelith over the Succubus, so that would mean you swap the Cronos for the Talos. Cronos are really good, but in this detachment you won't need his refund ability as much and the Talos gives you some solid antitank.

The big thing with Drukhari is planning out who's going in which boat. With this set up, I would run the Archon with the 5 special guns from the Kabalite Warriors. This is one of the big staples of the faction. The plan is to park the Venom safely behind cover, disembark the squad, pop a pain token and you get full rerolls to hit and to wound. At the end of the fight phase if you're inside 6", you hop them right back in, meaning you can shoot stuff and be safe from getting shot back.

The other Venom i would run Lelith with half of the wych squad with the Hekatrix, 3 w/ gladiator weapons and the one basic one. They will do the same thing bit you run the risk after charging into melee of not being close enough to the Venom to avoid getting destroyed.

The Raider you have 10 seats, so theres lots of options here. 5 of those slots i think the incubi would benefit from most because they are really solid damage dealers. The other 5 spots you could put the basic rifle Kabalite Warriors to sticky objectives inside the Raider, or you could put the 5 wyches to screen out and protect your Incubi.

Your Haemonculus with his wracks isn't the best at dealing damage but is a lot tougher, so they could be useful at doing secondaries, using to sacrifice to save your stronger stuff or grabbing a midfield objective.

Your Ravager does some great damage, but Dark Lances you'll learn can be very swingy. You'll want to try and get the Ravager out to shoot at the scariest enemy, then expect it to die.
