So it looks like in this build of the game: 2025.52.40.10089.1192642, Vivi is not counted as a wizard when interacting with effects. I noticed it with Cavern of Souls (Named Wizards) not making Vivi uncounterable. Additionally I cast Flame of Anor with Vivi on the field not granting me the choice of two of the modes. So it seems like Vivi is not being recognized as having the Wizard creature type.
