Not that I've really tried DT lately, but I'd imagine that you have to use the special summons as much as you can, and get your death gem production up as high as you can.
I can't even remember what the available living units are, but other than mages and priests I'd not bother much with the rest of them after say turn 20 (or whenever you convert to more of a summons based economy). Its not like the standard C'tis units are all that hot anyway, especially since you don't get the Dancers (do you?). Maybe you can use the slingers to better advantage though... bah, I can't remember what you get and don't get in DT anyway
