Shader help, looking to emulate a certain look.

I guessed a toon edge shader with black or white outlining. But an emissive shader that pumps either black or white and still accepts shadows? And I think there's some Ambient occlusion going on to? Using the new Shader graph if anyone can point me in the right direction, I cant code in HLSL yet, hoping I don't have to.​
