I've had an idea for a fun chaos list to use before I succumb to the vanilla marines codex. Basic idea is to use two level 3 sorcerer's, one with the burning brand and termie armour and the other with mark of nurgle and a sigil. The troops would be two squads of 8 marines with mark of nurgle and the standard of vengeance and a rhino each. The ubiquitous double heldrake and vindicators and a squad of 4 termies with mark of nurgle and a landraider. Then a nurgle level 2 psyker demon prince, and a squad of 10 demonnettes. I used something similar in a thousand two fifty game which was an absolute blast to play. Anything I've potentially missed, need to tweak? There is a hint of cheese but I don't mind
