I'm not quite sure what this army is trying to achieve. You lack numbers to control the board and objectives, you lack staying power because your units are so small, and your damage is meh at best. Revenants on the charge might do some damage, but anything that survives to hit them back will just evaporate them.
Chainghasts and Spirit Torments are good, but at this points value I think you're netting diminishing returns because they're only really buffing 10 Revenants.
Here are a couple options I'd probably consider at 1000 pts:
Allegiance: Nighthaunt
Mortal Realm: Hysh
Leaders
Dreadblade Harrow (90)
- General
- Trait: Ruler of the Spirit Hosts
- Artefact: Midnight Tome - Soul Cage
Dreadblade Harrow (90)
- Artefact: Aetherquartz Brooch
Battleline
10 x Hexwraiths (280)
5 x Hexwraiths (140)
Behemoths
Black Coach (260)
Battalions
Deathriders (130)
Total: 990 / 1000
Extra Command Points: 1
Allies: 0 / 200
Wounds: 52
Fast, and you have a block of 10 Hexwraiths are should be nigh unkillable. Use
CP to give them free mystic shield, and you're ressing 2D3 bodies every turn into them with the Coach and RotSH. The goal of this list is to use your speed to play the objectives, charging support pieces and units and using the charge move plus pile-in as extra movement towards objectives or board positioning.
Soul Cage to help you win your combats, and +1 to charge plus Wave of Terror on 9+ are all just pros.
I would say the Brooch to help farm
CP back, but you could swap for Pendant of the Fell Wind if you just want ludicrous speed (unnecessary
IMO).

This one is less speedy, but still objective focused. Reikenor and the Briar Queen control and debuff, while your Revenants omnom relevant threats. Dreadblade helps to farm
CP and uses his mobility to pull units to where they need to be, and 36 Chainrasps will give you solid board control at this points level.
You could drop 10 Chainrasps and take 2 Chainghasts to make your Revenants a bit fightier, but
IMO I'd go with more bodies.
