I found these Chinese MLP cards on Aliexpress & Taobao and my order finally came. Will be scanning and uploading them as I go.

This card is an “SSR” and you have a chance of getting one in every pack. These cards feature both foil as well as an iridescent crystal-texture over top. On this card, the musical notes, sparkles, and some outlines are foiled. The card number is F01-064

The back has no text but is different from the other kinds of cards. When I scan one, I will edit the description to link to it.
