First list and some thoughs:
I need effective multi-purpose units who can cover ground.
It will be 4'x4' tables, so deep strike may be more hazardous, and outflanking gets a bit more consistent.
I'm looking for early threats, MSU, and troop heavy....
I don't normally use SCs but Huron Blackheart really brings alot to the game for 160 pts, especially the Infiltrate Warlord trait (for up to all three CSM units, he'll hold the centre with the cultists)
Chaos Undivided - 999 points
