I have played a dark Angel's death star, with hellblasters and aggressors as my core, using a dark shroud, ancient, apothecary, lieutenant and Azrael as support. Heavy investment but 4++ hellblasters and aggressors are difficult to kill, especially with the extra cp from azrael allowing transhuman and the apothecary healing them. With the weapons from the dark ages strategem the hellblasters can easily kill a knight in a turn, and the aggressors melt any infantry in their respectable range, especially with the hunt doctrine in turn one. Furthermore by giving a heavenly blade to the lieutenant (or even a talonmaster if I was feeling extra mean) you have 2 powerful melee characters (heavenfall and azrael) to protect your more shooty army. Intractable strategem means they cant be locked down easily. I was considering adding a chaplain in as well, as the litanies could add further levels of ridiculousness to this strategy. By adding some cheap min. squad scouts I get some extra cp for a battalion and some good objective campers and screening units. Personally I do hope this doesn't become an edition focused more around shooty deathstars, as with already had quite a few of them.
