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 a "UR" and you have a chance of getting one in every pack. The card has rainbow foil on outlines and has a metallic effect all over. The listing also calls these kinds of cards "Dream Rainbow Cards". This card is number UR-002.

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.

There is indeed a small amount of text on the bottom right, which just has her name in Chinese. See my other card scans to see it more clearly.
