Ravager-3 Dissies
2x Ravagers-3 Lances
Razorwing-2 Dissies, Twin Rifle

Red Grief (The fast attack detachment)
Succubus-Splinter Pistol, Glaive
12 Reavers-2 Blasters, 2 Caltrops, 2 Heat Lances, 2 Grav Talons
10 Hellions-agonizer
5 Scourges-4 Heat Lances

2x Talos-Stinger Pod, Ichor Injector, Macro Scapel
Reaper

Basic Plan is to use a WWP to drop Drazhar, give him the Stratagem with the +1 PFP for the round so he can Assault Turn one and hopefully get turn 1 charges off with the Reavers and Hellions too while the Archon gives the Ravagers and Warriors the rerolls

I am not sure if Prophets is the way to go for the extra CP and giving the Talos +1 for their save or if I should go Dark Creed so my Reaper can snipe

Go Prophets, you'll need plenty of CP to do that little trick with Drazhar. If you fail that charge, though, you'll have lost plenty of CP and some hefty points.
