Delta Species Master Set Checklist & Cost

Variants in the Delta Species master set

The biggest family in the Delta Species master set is the plain Normal print, followed by the Reverse Holo family, which reaches Uncommon, Common and Rare cards alike. Holo prints form a third family, with Holo Set Logo and Normal Set Logo versions adding a stamped layer on top of the regular finishes. The smallest groups are Normal prints tied to named artists, including Miska Saari, Jun Hasebe and Akira Miyazaki. A reverse holo means the card art carries the foil pattern across the frame instead of the artwork window, so each one is its own binder slot.

Where the Delta Species master set's cost sits

As of October 24, 2026, 220 of the Delta Species master set's 258 slots carry a price. Value is heavily concentrated: the ten most valuable slots hold 47 percent of the master set cost, while the lower-value half of the priced slots adds up to only 2 percent. By finish, holos hold 60 percent of the total, reverse holos 31 percent and normal prints just 9 percent, even though normal prints are the largest group by slot count. The master set cost is therefore decided by a small cluster of holo slots, and the long tail of commons and uncommons barely moves it.

Hardest Delta Species master set slots

The hardest slots in the Delta Species master set are all Rare holos: Groudon Star, Metagross Star, Mewtwo δ, Umbreon δ and Flareon ex, listed in value order. None of them is a variant; each is the card's main holo print, so the difficulty here is the cards themselves rather than a hidden stamped version. Together these five slots hold 34 percent of the master set's total value, which means about a third of the cost rests on five binder pockets out of 258.
