>>38846721The real pattern is
>is the box Mon fire or water? Fire is "red", water is "blue"
This sets Blue, Sapphire, and Pearl in the "Blue" categories, and Red, Gold, and White in the "Red" categories. Anything that wasn't fire or water type ended up getting defaulted as the "other version" such as Silver and black being blue since Gold and white were red, and Diamond defaulting to red since pearl was blue
Everything before X and Y fit that theme. Then after X and Y they went by colors,
So X and Moon were blue, and Y was red.
