Well you have 4 Big Bugs, so you have some
MC action...
I've been doodling around with an "enhanced" Endless Swarm"
Winged Dakka'rant
Winged Assassin/ or Dakka'rant
Warrior Brood: Death spitters x2, Cannon
Warrior Brood: as above
Trygon Prime
Trygon Prime
Total cost~ 1140?
Endless Swarm Formation (~ 710? )
Warrior Brood: as above
Hormagaunt Brood x15, Toxic, x3 ~ 360ish?
Termigant Brood, x10 spine/vanilla, +5 Devilgaunts, x3 ~ 240ish?
That should run 1850, or so. The idea is to take advantage of the "return as was" effect of Endless. That should give a noticeble boost to the
striking power of the Gaunts. That is 9 Troops, 6 of which can re-spawn (4+) 2 Big Wormeys, and Two Winged Tyrants give plenty of
MC power as well.
Sorry about the "?" but this is off the top of my head...so the numbers need checking
Late entry: Well this does have a glaring lack of Venothropes, but I'd just use the Hormies as a bullet screen, just like the fluff

If they don't come back it will be bad....but thats the issue with die roll effects.

If you really can't do without....you can drop the Deathspitters, and a Hormie or three, and buy one that way....

You can also drop Big Wormey, back to Wormey, and get 80 points, drop two Hormies, buy two Venos
Sad little bump...Hey, please let me know how this goes (and what sort of list you ended up with...)
