Just make a custom dead faction, and add in the Resoln ability that allows them to cast Corruption (turn a shard in your control to a Death shard). Then always choose locations that can have at least 1 enchantment.
By late game you will have better growth in all your cities than a non-dead faction.
This would suck badly if it's a low magic map......
The other thing to notice about the dead team is, they pay NO wages. Which means, always always go to war. pump out millions of units. take over cities, and raze them afterward.
Abuse terror in tactical combat! you can take out 1 or 2 REALLY powerful enemies without casualties.
If you get a good production start, design your units to have the sprit trait (expnsive but 50% normal damage reduction). and also give them the trait that lets them grow to a group of 6 makes for a really powerful early to mid game units
I find this team, slow start, but really powerful mid-late game.
