Vayls Flying Circus @ 750 points

OMG, ARGH, and OH CR@P.

Vayls Flying Circus is supposed to be one of the trickier armies to fight against. Not only is it Legion Of Everbroken, who ignore practically all kinds of defence, its a type of list that spams the tricksyist models in Legion as well - Seraphs, Harriers, and Angeli. Coupled with the feat of annoyingness, this could be a very hard match up - especially since I havent played it before.

Things I can expect - 2 Angelius, at least 2 Seraphs, multiple Harriers, archers/striders with Incubi, and of course, Vayl herself.

The list im thinking of taking is the glorious Old Witch of Khador with her personal favourite, the Behemoth.

Zevanna Agha, Old Witch of Khador
> Scrapjack
> Behemoth
Gudrun the Wanderer
Kell Bailoch
Man-O-War Drakhun
> Man-O-War Drakhun (Dismounted)
Manhunter
Battle Mechaniks [4]
Great Bears of Gallowswood [3]
Greylord Ternion [3]
Iron Fang Pikemen [10]
> Iron Fang Officer and Standard Bearer
Winterguard Mortar Crew

Long range attacks to force squishy Everblight to come forward - Mortars and Augury Bombards to make him come to me. IFP with Weald Secrets and the GBs to pummel anyone hiding in forests and behind cloud effects (granting me some kind of eyeless sight) Drakhun - because hes awesome and countercharge might help with movement, Gudrun for tarpit and the Old Witch for her feat, which SHOULD stop Vayls feat from having much effect (they take damage when they move with OW feat up)

Thats the plan anyway - im open to suggestion + comments, ESPECIALLY if people have had experience with this type of army before. Id like to swap Kell out for something, like Alten Ashley, but I havent got his stats to do so. I also considered dropping some of the other stuff for a Koldun Lord with a Destroyer, but I would have to take a lot out of the list to do so.
