Yes, it's a secret rare, and is the extra sparkly kind, where the whole card has the little stars on it.
I'm quite interested in both your Magnezone Prime, and full art Resheriam.
I also have a JPN Dialga Lv.X and Mesprit Lv.x (both 1st edition), as well as a JPN Regigigas lv.x that I could through in to make it a fair trade if you would be interested.
