Well. Apparently I'm going to have to field this list alongside the Daemonkin: Khorne codex, since that one gets "Blood Points" for every units I kill and that die, that can be used to summon new units. So since I've maximized my personal chance to lose units... wham! Free Bloodthirster!
A Strength D Bloodthirster sounds tempting, too, even if it is a I1.
What sphinx of plascrete and adamantium bashed open their skulls and ate up their brains and imagination? Imperator! Imperator!
