It has a lot to do with the other civs that are in your game and what their alignment is.
Basically, you get Angels for units that are killed belonging to civs that are Good.
There's always been some question on what happens when a unit from a Neutral civ or a barb unit is killed. Does Hyborem get a Mane (if he is in the game), does it become an Angel or nothing happens?
I tried to view your save, but couldn't get it to work. If you have civs that are Good in the game and they have units being killed, you should be getting Angels.
You could always build cannon fodder yourself, send them out to be killed and you will get some Angels spawned in return.
I do remember playing the Mercurians once and this whole mechanism was not working very well, so you might be on to something. I just haven't played them in a long time.
