I'm glad to say that my Inter-Club losing streak has finally been broken; with the use of my very broken Tzeentch/Khorne list
Played a very nicely painted Slaanesh Daemon army:
Keeper of Secrets, Lvl2, 1 x Greater & 2 x Lesser gifts
Exalted Herald, Lvl1 with block of 29 Daemonettes
Exalted Herald on Steed with 9 Steeds of Slaanesh
20 strong Daemonette unit
3 Fiends
2 x 5 Furies
1 x Chariot of Slaanesh
1 x Soul Grinder of Slaanesh
Turn 1&2 - killed Soul Grinder with 2 hits from Skullcannons, Bolt of Tzeentch through the Chariot and Infernal Gateway to death Steeds from Lord of Change
Turn 3&4 - Keeper of Secrets and Fiends each kill a unit of Horrors, meanwhile both Skullcannons misfire and explode, my magic does minimal damage
Turn 5 - Flesh Hounds charge small Daemonettes and Fiends and destroy them, Lord of Change & Karanak charge the large unit of Deamonettes, but Herald cuts down Karanak
Lord of Change casts Infernal Gateway doing 8 Str10 hits on Keeper of Secrets destroying her.
Turn 6 - Flesh Hounds charge rear of Daemonette block while Lord of Change stomps all over Herald; end result 3 Daemonettes survive into his 6th turn at which point he concedes
2575pts vs 825pts Win to me.
