First list ever 3k

So this is my 3k list its suppose to be awesome sauce because the people at the place I play are supper elitist (lots of slanns chosen star ect....)

Kairos (spells im a lil unsure but im thinking)
Pha's protection, Briona's timewarp, Final transmutation, speed of light
Wyssan's wildform, transformation of Kadon, Flaming sword, Purple Sun(so scary to use)

HoK Armor of Khorne Firestorm blade
HoK Armor of Khorne BSB Greater icon of despair
HoT (life or light i think) spell breaker
The masque

10 netters banner of ecstasy (do I need a musician?)
39 bloodletters FC icon of endless war
34 bloodletters FC

5 flammers
5 flammers
5 flammers

Fiend
Fiend

Odd choices are I guess the netters I think being able to march 12 then basically make sure even if i lose the first round of combat they'l be there for another round seems invaluable (especially for setting up my hoards.)

Other thing I thought for 165 points to be able to LD bomb my opponents scariest unit was to good to resist. I think the spells for kairos could be better I just have a hard time picking(I want dwellers pretty bad as it heals + kills 1/2 to 1/3 a unit.)

Last thing the HoT lore is so hard to choose because I feel like he needs to be back up if kairos gets Psunned or brass orbed off the table. Life is good all around since my guys are strong but fragile and he can heal kairos when hes starting to feel the pain. while light is just freaking amazing for daemons in general.

Honestly any help would be greatly appreciated

Also on a side note I know kairos is pretty okay looking down 2-3 cannon shots a turn but....... how do you deal with that with other greater daemons.

BTW i just got all these models +

3 crushers
a great unclean one
keeper of secrets
30 plaguebearers
(have 10 harpies from dark elves to use as furies if needed)

You employ the good old-fashioned 'Fiend-catcher'!

Works with Bloodcrushers (or Beasts of Nurgle) too.

Deploy the Greater Daemon with a unit of Monstrious Beasts/Cavalry right infront of it - making it nigh impossible for anyone to hit the greater Daemon without first having to KILL at least one of those MB/MC models..

Remember that if the cannon-ball fails to kill something Monstrous it's stopped dead in its tracks!
