well, something to think about is the ability of chaos armies to place very accurate deepstrikers thanks to the rules for icons. any unit DSing with in 6" of one don't scatter so you can place them exactly where you need them, couple this with the fact that daemons can assult the turn they come in and a lot of options open up.
i'm having some good success with a variation of the old daemon bomb tactic. turbo boost some bikes up to a vulnerable part of your opponents battleline and use their icon to bring down daemons, termies and obliterators. the daemons charge straight in, supported by the bikers, and save the heavier stuff from getting shot at point blank, and the turn after the termies make their presence felt.
if you find youself with 140pts to spare and already have a solid HQ consider a khorne lord with a bloodfeeder daemon weapon. i've taken one in my last few games and he rarely fails to preform. sure, by the end of the game he's always dead having axed himself in the face repeatedly with the daemon weapon, i fact i 3 games the only wounds he's taken came from his own weapon
, but not til after he's killed at least 3 times his own points in enemy. the potential to roll 18 attacks for a single model on the charge is just too good to pass up
