I always make it a thing to make sure the arcana can match the Persona's lore.

For instance, Susano'o is actually both Fool and Magician, so a Persona from one arcana can in fact work for another arcana if the lore fits.

I'm just not so hung up on it here (unless I was head GM and original creator, but I'm only co-GM).

Also am still taking requests to design Personas.
