My spine, who took it!?

Every time I design tournament lists, I end up wishing for a ranged list, and every time I design one, I end up wishing I had pDenny running it. Just this morning I thought about running this list:

Warwitch Deneghra

- Nightwretch

- Nightwretch

Skarlock Thrall

Croe's Cutthroats (Croe and 9 Grunts)

Cylena Raefyll & Nyss Hunters (Cylena and 9 Grunts)

Satyxis Raiders (Leader and 9 Grunts)

- Sea Witch

The Withershadow Combine

Gorman di Wulfe

Master Gunner Dougal MacNaile

Satyxis Raider Captain

Warwitch Siren

Warwitch Siren

It's disgusting, includes just about every model I really like, but it's run by a caster I stupidly swore never to play again (outside tournaments). The thing is, that the last few games at my club, have been exceedingly hard (much harder than my last couple of tournament games), so maybe I could go back to pDenny, but I fear I'm just making up excuses to get a fix :(

Edit: I've been asked to explain why it's disgusting. While every list can be beaten, this list has so many tools to work with, and so many ways of locking down an opponent, that you need something special to survive.

• More than thirty ranged attacks in a round.
• More than thirty models with some form of additional damage dice.
• Run by a caster that can debuff an entire army.
• The list is almost entirely stealth or defense 15+

The list can throw out thirty ranged attacks during the Withering, and then charge in the Satyxis Raiders with Power Swell (targeting the two major threats that received Parasite/Crippling), leaving a completely devastated opponent, unable to effectively retaliate.
