Because the Strange Fake Jack the Ripper was summoned with a toy knife. Made a fake Servant that didn't have a proper form, but thought it was Jack

So from what I understand, a hokey half-assed summoning can create a hokey half-assed version of a Servant, that is still tangentially connected to the original.

Given how Musashi is apparently going to be summoned with a hokey half-assed ritual, it should sorta fit the bill, eh?
