i used my fluffy khorne list VS a shooty deamon tzeentch list the results was a loss but thats not important.
firstly the chaos book is great my main problem is too much choice i think this is phill kellys best codex yet!!!
as for the units hell drakes are great although against a full infantry list they didnt do as much as id hoped
the forgefiend was pretty gd again i reccon against more vehicles it would do better
same for the hell brutes
the deamon prince i could easily write an article on these by them selves he was great he lost 2 wounds turn 2 to a herald but after that right up 2 turn 6 ish he chopped his way thru allsorts of little deamons
the berzerkers im still struggling to get to grips with disembarking theturn before i want 2 charge. the rhino wall kinda helps bit more foresight shud help well see over the next few games
