Took me a moment - AL= Army List
I suppose you could use the Archon Claw Agoniser and the Sybarite Claw agoniser to theme your minis. Convert with these for Reaver/Wych Succubi.
I'm guessing the Bronze Hands would prefer close combat, since theat lets them use their hands to kill directly. A close combat raider army might fit your needs well and be effective.
Use lots of Bronze and tin bits in your painting...
As for AL, well, it's traditional for you to start somewhere and us to direct you along, make fluff suggestions whatever. The point we need something to work with. Theres some great sample armies already on KeirAriq's great article at the top of the page. Perhaps there's some units you already really like and want to include in your army?Tell us, so we can help you build an army you'd like. If you want sample army lists, theres plenty in the thread. Right now at tournies I tend to use a raider heavy army with Wyches and Warriors led by a lone Archon with Reavers, Hellions, warp Beasts and a 3-Dis Ravager backing it up. But I like to mix it up a bit, Hellions in particular are not a traditionally easy to use DE unit at all. I enjoy them, which is why I take them. ALs are a reflection of personal taste, IMHO.
