Night Widow: All melee claws, Soul mastery ninja build?

I think Night widows look very ninja stealthy.
Looking foward for a twist for my widow, turning her into a deadly stealthy ninja with only claws attacks and some Soul powers.
Any build that fits into this?

This is mine, which fits your concept more or less - no promises about quality however. If you wanted to drop Eviscerate then you could take another Soul power and have plenty of slots to throw around; you could also drop Elude and take a 3rd Soul power but I kept it for the "I don't care how many Def debuffs you've thrown at me you're still not going to hit me with any attacks" ability.

It's softcapped to Melee and Ranged without Mind Link and Perma-Mind Link without hasten, so there's a lot of headroom and you don't need a bunch of Purples (just a bunch of LoTGs). Though if you can afford the purples you can make it perma-hasten as well pretty easily.
