If you activate Lazav, the Multifarious to become a copy of a creature in your graveyard with Grandeur like Korlash, Heir to Blackblade, then return the creature in your graveyard to your hand somehow like with Phyrexian Reclamation, can you then discard the creature with Grandeur to Lazav's new Grandeur ability? I think so because of rule 201.4:
What's tripping me up is the use of "another" in the Grandeur ability itself.201.4 Text that refers to the object it's on by name means just that particular object and not any other objects with that name, regardless of any name changes caused by game effects.
