Heres my radical sm 1000pts army lsit

Hq Epislotory w/ term armor, storm bolter, fear of darkness
ordo maellus Inquisitor lord w/ power weapon bolt pistol, and scourging
Retinue: 2 acolytes and 1 familiar

Elite 2 Daemon hosts

Troops 2 X 10 spacemarines w/ meltagun, missile launcher, and termie honours for vets each

Heavy support 2 whirlwinds

the idea is to have the sm slowly advance while whirlwinds allow me to take control of the field, the librarian might tp in or just use fear whenever he gets near the enemy, and the deamonhosts will just destroy as many enemy things as possible. Any Suggestions would be much appreciated.
