I've decided on a experimenting with a hybrid list involving good amounts of stealers and monstrous creatures. It won't be fully zilla or stealer rush, but trying to mold the positive aspects of both. I will try to use scuttlers to improve my overall speed and get everything into close combat on turn two. The monstrous creatures will give me my anti-vehicle and be targets themselves.
List:
Hive Tyrant - Wings, Toxin Sac, and 2 Scything Talons
Hive Tyrant - Enhanced Senses, Toxin Sacs, Venom Cannon, and TL-Devourer
2 Tyrant Guard
Carnifex - Enhanced Senses and 2 TL-Devourers
6 Genestealers - Extended Carapace and Scuttlers
6 Genestealers - Extended Carapace and Scuttlers
6 Genestealers - Scuttlers
6 Genestealers - Scuttlers
12 Spinegaunts - Scuttlers
12 Spinegaunts - Scuttlers
3 Raveners - Rending/Scything in 3 FA slots
1 Zoanthrope - Warp Blast and Synapse
1 Carnifex - Enhanced Senses, Venom Cannon, and Barbed Strangler
Total: 1500
The TMC's should be able to handle vehicles pretty well with the elite fex best against light vehicles, tyrant against medium, and heavy fex against heavy. Hopefully, I have enough synapse with the three creatures with one being very durable. The stealers with carapace will scuttle into the open if needed and hopefully carapace gives the protection needed. The other stealers scuttle behind cover. Spineguants are meant to tie up units so they can be dealt with later.
By looking at their respective movements: flying tyrant, stealers, spinegaunts, and raveners all move at the same pace of around 30 inches on turn 2. That way, everything hits at once. Not sure how well the list does at escalation. The zoanthrope provides synapse for the gaunts, but at the same time they have to hide. The monstrous creatures are fairly effective coming on the board with guns/speed, but seperation between the units deployed first moving forward on the table and the newly arrived units could be problematic. Pretty small list that depends on speed and coordinating assaults/shooting.
