Alright, due to Aduitore7 I going to make a list of possible do's and don'ts.

Permanently irreversible laws=No God or Death. That's a given.

Proposals made by Auditore7:

1) No Archangels or Horsemen (which would extend to mean NO usage of any of their rings, as they're intertwined).

2) No Jesse Turner, as he's increasingly powerful.

So, what should be the strongest character allowed to be used? Cas, while wielding all of Purgatory's souls?

Cause if we do this, we'll be left will flimsy characters, like monsters, ghosts, Leviathans. Which makes it no fun.
