I play:
T Banshe general hatred for live (first command trait)
Spirit Torment with Midnight Tome
Knight of Shrouds with Sword of Judgement of ulgu
Guardian of Souls.
30 chainrasp
10 chainrasp
30 grimghast
20 dreadscythe
5 dreadscythe
8 Myrmourn
4 Myrmourn.
I dividethe army in 4 different departments, which I will send to attack or defend on 4 different objectives.
The reapers are accompanied by the guardian and 4 Myrmourn, the idea here is to have a unit that hits 4+ by rerol the failed and towounds at 2, with the Banshees canceling the opponent's shock tests.
The 20 dreadscythe are accompanied by 10 chainrasp and the spirit of torment, they target the opposing unit with the lowest bravery, the spirit also launches suffocating Gravetide for a further -1, chainrasp screen to avoid being charged and then they protect the hero.
5 Dreadscythe and the banshee usually remain in defense of the objective in my territory, along with 30 chianrasp that so repeat the 1 to hit and hurt, the dreadscythe give a -1 to hit the opponent, lined up just behind the chainrasp.
The Kos and the 8 Myrmourn instead hit heroes and small armored units, the idea is to bring save throws from 3 + / 4 + to 5 + / 6 +, and hope to make 5+ with the Knight of Shrouds and inflict some d6 of mortal wounds to enemy heroes.
It is not a simple list to manage, indeed, but I love the BG of the shrieker Host and banshee so I want to run a list focused on them, this is the one that from field tests seems more balanced, but the success and defeat are linked to many different factors. For example, against the demons or death the dreadscythe have no way of giving the -1 to hit, but they too must repeat the 1 on the shock tests and if they suffer 15 20 wounds will have to lose other models for the failed test.
I have never faced the order draconis, but it seems to me on paper an army that deploys few models, in that case I would try to take control of the field, but without facing them I can not tell you more.
Sorry again for Long post
