A lot of people are going to look at this and scream at me for the cost of the transports. I know this. I realize why this is. but I swear, this actually works because of a few key aspects of what's going on in the play style and the unit synergy.

The key here is unit synergy, and setting out very specific purposes for my units at the start of every game. Infantry are killed by the Warriors, Razorwing, and if there are no more vehicles to shoot at by the Voidravens. Thanks to the 4 missiles each turn they do a spectacular amount of damage vs. hordes., and the 3+ poison on the warriors thins out monstrous creatures and high-toughness units rapidly.
The Wyches are generally a pair of suicide squads. It sounds strange but it's true. they go in, find the biggest, toughest thing available and hit it as hard as possible even if they can't typically win against it. Against a few things, the Hellions will assume this purpose but generally the Wyches and their 4+ invul in close combat makes a huge difference. Duke gives them options on the combat drug rolls, it's rare that I don't take them without the Pain token if it's available but S5 on those hellions is pretty sweet too. With the Pain Token, they typically go immediately on tank hunting duty where the FNP protects them from explosion results and where their haywire makes them threatening to units that might otherwise be out of danger. Hellions with S+1 are also amazing at that role, if they can get a pair of pain tokens quickly.
The real gamewinner here is the unit of 20 hellions mixed with the Baron. In missions where they are tasked with capturing an objective, I place objectives as high or deep in terrain as possible (preferably 2+ ruin levels above the ground) and use their superior mobility to place them out of harms way, where they can make the most use of the Baron's stealth. You need to pull 6 of these off in one round of shooting to successfully force a morale check, and if they are already on top of a covered objective going to ground for a 2+ cover is very useful.
