Planning a Strange Druid Through Mid-Levels

[wayfare]

Hey all:

I'm playing a druid that is also something of a duelist (he uses 2 weapon fighting with the spell Flameblade as an off hand weapon). I was just wondering if there is a PrC that could give me a melee boost while (mostly) preserving spellcasting?

Daggerspell Shaper (CAdv) is a TWF rogue/druid mix prestige class that advances spellcasting, wildshape, and sneak attack.
