Tyranid army list vs spacewolfs 2500

[thebugmaster]

Hello! I am playing against a space wolf army soon. The opponent is terminator heavy along with thunder wolves, and dreadnoughts. The following is my army list I will be playing against him. I am looking for any tips or critique. We will be playing with one victory requirement, which is to table the opponent. Thank you for any input.

HQ
dakka flyrant - haywire
Dakka flyrant - shred shard beetles

Elite
Zoanthrope
Venomthrope
Hive guard x2

Troop
20 hormagaunts + toxin
15 hormagaunts + toxin
30 termagants + toxin
Tervigon with shred shard beetles & cluster spines
Genestealers x6 + brood lord
3 warriors + barbed strangler

Heavy
Mawlock
2 dakka fex
"Crab fex" with adrenal glands and crushing claws
T fex with rupture cannon and haywire grubs
Biovore

Thank you for any replies
Also; I do not own an exorcine so I cannot use one.

This list will probably get shredded if your opponent has a hard list and a clue of how to play it.

I take it this is a friendly beer and chip game?

I'll just quickly chip in with:
Rupture Cannon is pants
Biovores and Hive Guard are best when taken in full broods of 3.
