Literally my last post was an experimental Shaddoll build, now I'll post one less experimental, Shaddoll Lightsworns.
Lightsworns help abuse Shaddoll graveyard effects, get out Construct for basically free, and since they're light and dark, you can splash in Chaos cards like Envoy the Beginning and Chaos Sorcerer. The only thing about this build that might be a bit iffy for people is the 1 Shaddoll Fusion with... way more than enough Fusion monsters to justify running 3 and you're probably right, but I find the current build works enough for me.
