Rare Versions are harder to find versions of a Series' release. They may have different looks from a character's common looks such as variant skin tones and small "flair" such as tinsel in the hair or glittery accessories and clothing. There is no package differentiation such as unique backgrounds.
Rares are found in about every forty packages. They are marked with a diamond () on the Collector's Sheet and a ♦ on lists here.
