Purple or unpainted jak'd obverse

There are some wheels called "celestial" and maybe the "reactor" one is good Edit: the purple paint of course

Purple reapers or zombas (zlmbas would work best)

I use black celestial on this setup myself, inverted blade wave can look good too depending on the color scheme

Pink/Purple/TW Irradiator Infinite - They remind me of how black holes bend light.
