I think that you can shave quite a few points from your new list which could give you the potential for a second team of genestealers (this is suppose to be a broodlord heavy list)
if you have less infiltrators then the Swarmlord would be better as a flyrant instead.
I prefer the trygon over the carny since he is much tougher and ends up being cheaper, sure they dont shoot as much but they are much stronger in close combat and very scary so the psychological effect of them coming into your line is pretty nasty.
list could look like this
HQ
Flyrant w/dual
BL devourers=260
Swarmlord with guard = 340
Elite
Doom of malantai in
spod = 130
Troops
5 genestealers with Broodlord
Scything talons on
BL=132
4 genestealers with Broodlord
Scything talons on
BL=118
10 Termagants=50
10 Termagants=50
Tervigon
Catalyst , cluster spines, toxin sacs=185
Tervigon
Catalyst, cluster spines, toxins sacs=185
Heavy support
Trygon=200
Trygon=200
Total 1850
only 2 powers on tervigons keep Catalyst for the
FnP and less dice roling to figure out powers for speedier gameplay.
took out the
TS on genestealer since those are wasted on meatshields. (yes I know it helps get more rending hits but not if they dont reach
CC)
maybe a flyrant with hive comander could be good too instead of Swarmy but I felt you wanted the Lord of Swarms in your list
