i would suggest dropping the sorceror and adding a vindicator with daemonic possession for 145 pts and maybe defiler with close combat arm, or another vindicator.
cause ur versing nids ur going to want to have lots of pie plates floating round.

drop the daemonic possession and havoc off the rhino, r u going to use the rhino to get them into cc early?? and replace the heavy bolter with a flamer (u want templates).

i would take a vindicator over the havocs, though a 5 man havoc squad with 4 auto cannons does sound menacing (5 marines, + 4x auto cannons + IoCG= 165pts), they will take down any of there bigger MC's and do alright if u play them well, but will get railed if they ever get into close combat.

EDIT: the possessed squad only costs 170 as stated by fallen.

hahaha yeh i know hey!!!!!!! cant believe someone worked it out!

another thing u could do then is change the sorcerer for another DP, with same stats as above. that will work well.
