1500 Marines to play MC heavy nids

I have a game sometime within the next week that will be against nids, and they will quite probably include:
A hive tyrant, broodlord and retinue, 2 fexes and 3 zoanthropes, all rounded off with a healthy number of stealers.

so onto the list:

Chapter Master - 180
- Artificer Armour, Relic Blade and Hellfire rounds

10 Man Tactical Squad - 170
- Flamer and Missile Launcher

10 Man Tactical Squad - 170
- Flamer and Missile Launcher

Dreadnought - 125
- Heavy Flamer and Assault Cannon

Dreadnought - 125
- Heavy Flamer and Assault Cannon

6 Assault Terminators - 240
4 Thunder Hammer and Stormshields, 2 Twin Lightening Claws

10 Devastators - 300
Plasma Cannon and 3 Lascannons

Land Raider Redeemer - 240

total: 1500

- Im working on the principle that things work better in pairs, which i have picked up from various places. hence 2 dreadnoughts.

- Hellfire Rounds on the Chapter Master are there as the last time I killed a fex, it was a Captain with that wargear combo that did it, putting a bolter shell in its brain.

- Devastators will hopefully at least put wounds on the expected MCs, and if the tactical squads are split into combat squads, thats 2 squads to flame stealers, 2 squads to put missiles into zoanthropes.

- Land Raider Redeemer for its lovely flamestorm cannons, with its cargo of CC Termies to hopefully take down any remaining MCs

Because Nids struggle vs Armour, I'd suggest DakkaPreds over Devvys.

If you MUST, then ML all round.
