If you're going for super assault, drop the shrikes and give the Tyrant wings. He'll withstand much more punishment than the shrikes will and gives off a nice synapse field himself.
The primary problems your army faces are, like you said, armour and flame throwers. To counter armour i'd honestly pick up a base trygon with poison. These things are killing machines when they get their chance in small points games. She will act as a diversion as well and draw fire from your Hive Tyrant who will more than likely be absorbing all the fire power being thrown at you.
I know you want numbers, but hows does 7/8 (depending if the Trygon fails it's synapse check) hits with both re-roll to hit and re-roll to wound with another hammer of wrath attack thrown in on top sound?
Make you're Tyrant much more lean as well, drop toxic miasma and regeneration. Roll on Biomancy, with luck you'll pick up number three which will give you "It will not die" as well as "Feel No Pain!" You might even get Iron Arm, and thats where the fun begins with MC's. If you want a monster in close combat drop the devourer's and use the base talons to save you a few points, spend 10 of the 15 points you saved from the devourers on toxin sacs which will give you re-rolls to wound. Combine that with acid blood and you're more than likely going to get quite a few kills in squads.
The recommended build for a tyrant in this kind of army is:
Tyrant, Wings, LW/BS, ScyTal, Acid Blood, Tox and Old Ad (260pts) * Im a dumbass...
This will give you 40 points spare, dropping the shrikes entirely will give you 205 points in total, drop a gargoyle and even up the squads then you have enough room for a poison wielding Trygon.
This is just my advice. Take from it what you like. This list is incredibly squishy and the flying across the board might get a load of units killed. You need to be careful with your spore placements as well. The units tend to get hosed down as soon as they appear from the pod and with no shooting attacks they cant really do much till the next turn.
Even though you walk through the valley of the shadow of death, I'm there waiting... and your not coming out alive!
