What is the rarest shiny in S/V?

I need to know which Pokemon I should prepare for when filling out my shiny living dex.

There are 3 options for Rarest Shiny Pokemon (that isn’t shiny locked):

-> Maushold family of 3-> 3 segment Dudunsparce-> authentic Sinistea/Polteageist

The first 2 are both forms that have a 1% chance of occurring at the time of evolution. Whether they evolve into their more common form or the rarer form is completely out of the hands of the player – it’s based on hidden information that the player can’t even see, and nothing the player does can change it.

Sinistea/Ploteageist are a little different situation. The Pokemon is inhabiting an antique tea set, the originals of which are extremely rare and therefor valuable. But a multitude of knock-offs were created in an attempt by others to cash in. As a result, most Sinistea/Polteageist are the Phony form. The significantly rarer Authentic form can be determined by locating a tiny stamp of authenticity on the rim of the underside of the teacup/teapot. Unfortunately, there is no way to manipulate the camera in such a way as to locate the mark, when encountering them in battle or in the world. Your only option is to simply catch every one you come across, then check it’s summary and rotate the camera to examine the rim on the underside. Even worse, you can’t breed Authentic Form down – any offspring of an Authentic parent will automatically be Phony Form.
