Seems a pretty terrible list to me, not sure why you have that farseer either... for Doom? That's a lot of points to reroll some wounds if that's the case.
I assume you had the wytches in a raider with 2 succubi and the archon, that's a lot of eggs in one very thin basket.
5 troops with warriors and a single blaster in a venom is also a pretty sub par way of running those, 3 mandatory troops is fine but then go for trueborn and some more firepower.
Again, not so sure what the Skyrunners can do for you either, in this list.
If you could explain a little more on how you actually ran them or what you were trying to achieve then we could definitely give you some feedback.
