What this is
Where new card rarities first appear in Japan: all three new rarities since 2022 debuted in premium packs priced 1.5 to 1.67 times the standard pack per card.
How it’s built
- Official product pages name the pack each new rarity first appears in.
- Price per card is the list price divided by cards per pack, compared with the standard pack on sale at the same time.
What we assumed
- Three cases are enough to show a pattern.Every new rarity in the period followed it, but three is a small sample; the research grades it B for that reason.
Sanity check
The prices are list prices, not what buyers paid. In English, the Mega rarity also debuted in a special set, which is consistent.
The value
- Share debuting in premium tier: 3 of 3
