I am a tourney goer and I played
DE all through 5e. I disagree with Atlati Jones; this list won't do much.
DE either shoot a hella lot ... or they used to hit with wyches, grotesques & wracks, and Talos & Cronos.
This list doesn't have enough of either.
My 5e list had 21 Dark Lances/blasters (or 24). Yours has 15.
My same list had nearly 30 wyches. Your h2h is 9 girls, Leli & Drazhar, and 8 incs.
Not even a full 20 elves.
Lelith will wound most things on 5+. No character on a 25
mm base wrecks units anymore. Most 32
mm based characters (they were on 25s) have suffered an 8e generalized nerf, with 4 to 5 smacks per phase. It takes Bobby-Billy, a
DP or Morty to single handedly wallop a 10 man
MEq down to 1 or 2 left, likely to die to Morale.
That awful bit of critiquing over, let's tool up your crew:
a. Truborn ought to carry blasters.
b. The 15 Dark Lances wiill make short work of Mortarion or Magnus.
c. For Troops, go whole hog with all Kabalites for shooting. The 9 wyches are wounding most of 8e on 5s (splinter pistols aside) and won't hold up. Shelve them. Again, sadness.
d. demote Lelith to a Succubus. I know you're already flush with extra points, but there's not too much point in spending so heavily on Lelith (I have a pro-painted model of her ... shelved since an 0-3 tourney last summer.
Tears. Tears.
e. Points left? buy a 3rd Ravager for more
DLs.
f. gear upgrades - Dark Lances with the Kabs, and usually take the upgrade best toy for Incubi sergeants and hekatrix leaders.
And bring Preperation H to your next tourney. You have a long up hill road ahead.
Thoughts and Prayers.
srsly, good luck and study up on enemy strategems.
