The Great Enemy, Slaanesh!

So with the points circulating slaanesh daemons seem a lot cheaper and the new Infernal Enchantress looks great! Anyone know a great deal about them? How does this list look;

Batallion +5cp

(WL) Infernal Enchantress Celerity of Slaanesh

Masque of Slaanesh

Keeper of Secrets 

2×30 Daemonettes

1×20 Daemonettes

2×3 Fiends

Spearhead +1cp

Slaanesh Daemon Prince; double malefic talons, wings

Herald of Slaanesh on Seeker Chariot

3× Seeker Chariot

Outrider +1cp

Slaanesh Daemon Prince; double malefic talons, wings

Herald of Slaanesh on Seeker Chariot

3× Hellflayer Chariot

I've left 90 or so points aside for the Enchantress. Had an idea of her sprinting up the board And summoning the Keeper turn 2 to stop the Keeper being blasted off the board and depending on how that comes off summon the 20 daemonettes with the stratagem. The two chariot heralds make sure everyone maintains their +1S buff before joining the fray so it's quite a mobile force.
