The promotional card attached to Moon One is available as a loose card in the 24-pack boxes. It is MLPE-PR-002, a reprint of its Chinese counterpart, YH-PR-050.

This exclusive promotional card was available by swinging by the Kayou booth set up at NYCC Comic Con 2025, the official launch of North American Kayou products. Unfortunately, the sticker on the card is only on top of the sleeve the card is in - if taken out of the sleeve, the card becomes no different than the card you may pull from the box. The owner of this website actually removed the sticker from the sleeve and slapped it on the back of the card to solve that problem.
