I have posted on a topic similar to this before, but with the provision of the Flying Tyrant Model, this is such a good model, I wanted tp see what folk thought of this list at 2000 points. In particular, I am yet to purchase the two Trygons, so if there would be a better way of making this list work I would be interested.
HQ - Flying Tyrant with Hive Commander
Elites - 9 Zoanthropes. (I have managed to get six more from E-Bay as metal models)
Troops - 4 squads of vanilla Gene stealers
Fast Attack - 2 squads of 15 Gargoyles with Adrenal Glands and Toxin Sacks. I love these guys too !!
Heavy Support - Two Trygon Primes.
Number of things to think about
1) I only need synapse for the Gargoyles, to begin with this is provided by the Zoanthropes and after that by the Montrous creatures.
2) With the Hive Tyrant OFF of the table in reserve for turn 1, I understand the Hive Tyrant's Hive Commander still works. It only fails if he dies, that way I should get two Montrous Creatures into play on turn 2 with Synapse Control for the Gargoyles
3) The Genestealers become more flexible coming onto the table after the first Trygon Prime arrives since they can use his "tunnel"
My view is that this will be an army that will be confusing for target priority for my opponent. There are very good reasons to want to shoot anything that is still on the table immediately.
Comments will be gratefully received.
