Ok, since the tactic is officially dead competetive wise, its best time to start using it

Here is my 2k attempt for Bash brother's concept, that includes 3 detachments,
TS supreme command, Death guard super heavy auxiliary, and daemons patrol.
Ahriman on disc 166pts
Daemon Prince of tzeentch, Wings, Talons 195 pts
Daemon Prince of tzeentch, Wings, Talons 195 pts
8 Scarab Occult Terminator (7+ 1 sorcerer) 268 pts
Magnus 445 pts
Mortarion 470 pts
The Contorded Epitome, Warlord, Celerity of slaneesh, The forbidden Gem 195 pts
10 Daemonetts 60 pts
1994 Total points, 4
CP Ok, lets start with explanation
The contorded epitome in pure slaneesh detachment allows me to advance and charge both in the same turn, which means that I have 15"+
3d6 to reach my opponent turn 1.
If i manage to hit my opponent screen turn 1, they will be locked in combat without fall back, which is goin to give my big dudes survivability.
I use forbidden gem to turn off characters that either have best
CC to counter me up, or give best buff (via magic or abilities) to the opponent army.
Mortarion warp-timed by ahriman/magnus have 12"+12""
2d6" to reach my opponent turn 1 and lock himself in combat close to the epitome so no fall backing allowed.
Depends on deployment of my opponent and mission that we play I sometimes just rush up Magnus and try to charge turn 1 with 16"+
2d6 The rest of the army moves to the middleground, I use 1
cp to give one of the demon prince DMC, which allows me to teleport my scarab occult terminators in front of my character blob (ahriman & 2xdp). They also dish out quite a nice
dmg.
There is not much room for changes, but I see 2 that I could possibly consider:
First swapping 1 daemon prince for exalted sorcerer on disc, which would gave me points to change daemon patrol of Epitome+10 daemonetts to a daemon vanguard with Epitome+3x1 Fiend of slaneesh
This change gives me 1 additional command point, and also 3 units to leave back on objectives rather than 1.
The other change I could possibly think of, is cutting up wings from both daemon princes to add up 2 more scarab occult terminators (both with soulreaper cannon).
That would give me a little less mobility on my hero blob, but more resistance to the shooting as well as a little extra firepower (they gonna be most likely one of only legal targets for my opponents)
Please, let me know in the comments what you think of this list, is locking up people in combat realiable way of protecting primarchs, can I clean up board fast enough to not loose badly on missions, and last but not least what you think of "changing options" suggested by me.
