I played a 1500 point game against Slaanesh. The Slaaneshi list was really bad, but I have proved something: Against any Daemon-oriented army, move forward as fast as possible. Take advantage of your number advantage early!
Anyway, I played this list:
Harlequin Army list
HQ:
Shadowseer
Psychic Powers: Veil of Tears, Impetuousness of Youth
Familiars: 4
Wargear: D-Field, Dread Mask, Powerblades
Weapons: Harlequin’s Kiss, Shuriken Pistol
216 points
Great Harlequin
Masque: Red Death
Wargear: Dread Mask, D-Field, Tanglefoot Grenades, Powerblades
Weapons: Harlequin’s Kiss, Shuriken Pistol
165 points
Elites:
Solitaire
Wargear: D-Field, Tanglefoot Grenades, Dread Mask, Powerblades
Weapons: Harlequin’s Kiss, Shuriken Pistol
165 points
Troops:
3X:
5 Harlequins
CC Weapons: 1 Harlequin’s Kiss, 1 Power Weapon
Pistol Weapons: 2 Plasma Pistols
Troupe Leader
Wargear: Powerblades, Tanglefoot Grenades, Dread Mask
Weapons: Harlequin’s Kiss, Shuriken Pistol
Venom
Holo-Field, Fusion Gun
317 points
1497 points
The only things I lost were 3 Harlequins and the Venoms (Defiler Reaper Autocannon is great against AV 10)
The Slaaneshi played:
10 Chosen w/ Bolt of Change, Lord too
Defiler w/ Indirect
27 Horrors
The Horrors got no chance to shoot, I was too fast.
Regarding playtesting:
The Shadowseer power Impetuousness of Youth is WAY too good. I mean, my Solitaire could go 38" a turn. This either needs to be toned down or raised in point cost.
You have very little incentive to use Mask of the Red Death. You should be able to kill them easily in two phases if you have good wargear, etc. Therefore, it doesn't really help that much. It is only good with DJs if they get in combat, but then again they should be separated and one DJ dying shouldn't really affect you.
Familiars are quite good. I believe that the Benthai however should give something like this:
1st:+1 WS
2nd: +1 WS, +1 A
3rd: +1 WS, +1 A, +1 S
Initiative isn't that good for a Shadowseer but S/A/WS are.
I hope this helped, Rasmus!
