Played couple of similar lists, first was with 6 horrors instead of arkhan, doppelganger cloak (before nerf) on ZD (general, majestic horror) and miasmatic blade on TG, won a local tournament pretty confidently
Second was for 2250 tournament with arkhan, more ghouls, courtier and some CPs, doppelganger cloak (again, before nerf) on TG general with magestic horror and flayed pennant on patrol's courtier for summon flank charge
Then, yesterday got my ass kicked, used this list: Allegiance: Flesh Eater Courts- Delusion: Crusading ArmyMortal Realm: UlguLeadersAbhorrant Ghoul King on Terrorgheist (400)- General- Trait: Magestic Horror - Artefact: Miasmatic Blade Abhorrant Ghoul King on Zombie Dragon (440)Crypt Ghast Courtier (80)- Artefact: The Flayed Pennant Crypt Ghast Courtier (80)Battleline20 x Crypt Ghouls (200)20 x Crypt Ghouls (200)10 x Crypt Ghouls (100)Units6 x Crypt Horrors (320)BattalionsGhoul Patrol (180)Total: 2000 / 2000Extra Command Points: 1Allies: 0 / 400Wounds: 114
So what I can tell - arkhan is very good to have an upperhand in magic play going to use him more, and ghouls in units of 20 are having big troubles surviving during the game when hit hard because you don't really have CPs to spare for passing bravery early in the game, if you get alpha striked hard enough say good bye to your expensive 200 points unit that is supposed to win you mission so I will be tweaking some things until I find whats the most optimal.
