I got 6 big Monstrous Creatures, 2 flyrant is decent
AA, and lots of suprise with up to 10 units Flanking or Deepstriking.
Synapse is decent with a Tervigon on top of the two Flyrants especially since this list doesnt need synapse too much.
The opponents leadership will be sorely tested and weakened quite a bit with the Death leaper and the assassins, the Shadow in the warp and the amount of fear causing units I have (12), plus some decent shooting for pinning tests. Enemy psykers will have a really hard time casting
what do you think guys?
