1000pt escalation league list

[wineburglar]

So some things I failed to mention in my last post which in hindsight would probably make a huge difference are that in the campaign I am playing in we were allowed to have a character outside of force org that was able to "level up" and gain some abilities. So my character has now evolved into a trygon prime that is a level 3 psyker and has a 2+ save. As for the campaign rules I am now allowed to take a free heavy support of up to six wounds with no point limit as well. For my 1000 point battle forged list I am thinking of running:
Free:Trygon prime w/ regen, toxin sacs, toxin spike
Dakka flyrant
tervigon w/ crushing claws
30 termagaunts
venomthrope
zoanthrope
dakkafex w/ AG
Exocrine
free heavy support: tyrannofex w/ regeneration, toxin sacs, ag, acid blood, dessicator larvae, acid spray
any thoughts or criticisms are greatly appreciated
