Read as a collector, that table is the set's personality: 10 Double Rare ex anchor the playable chase, 22 Ultra Rares carry the full-art treatments, and 34 Illustration-class and Hyper-class cards form the art-first tier that most collectors actually hunt. Read as a player, the same table is a shopping map — the Double Rare line is where the format's tools live.
