Clefable's wish came true!
I assume you are asking about this site? https://www.smogon.com/cap/pokemon/Why is the Chromera sprite and Venonomicon sprites missing from the smogon website?
I don't believe anyone has access to it which is why it hasn't been updated since Kerfluffle's project. At this point, you can find all the information that would've been there between the strategy dex and the showdown pokedex.
