Generally 1 swarm unit in front of 2 horde units. If my opponent does not have shooting, the swarms back up the hordes (cheap support).
Flyers are each independant.
Cavalry is brigaded as 1 hound, 1 Cavalry and 1 Chariot. One brigade will have 2 chariots and 1 will have 2 cavalry. Hounds out front to draw missle fire.
When I played this game against Graymatterblues, I brigaded my infantry into two brigades of 1 swarm unit and 3 horde units. The leftover swarm unit was parked in the middle of the woods and left there.
No dispell scroll. I decide to go for a purely aggressive list. Wings are not needed on the characters because I have two units of flyers.
I found beasts to be too expensive. Same with the Greater Daemon. Although, if I had a dispell scroll, the beasts might be worth it. When I did have beasts, my Undead opponents would target them with Doom and Despair which made it hard to use them at all!
