Aquapolis Master Set Checklist & Cost

Variants in the Aquapolis master set

The Aquapolis master set is built mostly from two large families, 152 reverse holo slots and 151 normal slots, with 35 holo slots on top. Reverse holos are not limited to the commons: they appear across Common, Uncommon, Rare and Holo Rare cards, which is why the reverse holo family sits so close to the normal one. The remaining slots are small and specialised: 5 Reverse Holo Jumbo versions and a handful of normal prints carrying the names Kevin Nguyen, Chris Fulop and Reed Weichler, each a separate binder slot.

Where the Aquapolis master set's cost sits

The Aquapolis master set cost is spread more evenly than the holo-heavy checklist suggests. The ten most valuable slots hold 27 percent of the total, while the lower-value half of the priced slots adds up to only 9 percent. By finish, holos carry 44 percent of the value, reverse holos 40 percent and normal prints 17 percent, so the reverse holo run matters almost as much as the holos. As of October 24, 2026, 343 of the 349 slots carry a price. Totals for LP and up sit 29 percent below Near Mint, and MP and up sit 28 percent below.

Hardest Aquapolis master set slots

The hardest slots in the Aquapolis master set are led by the holo Houndoom and holo Umbreon, both Holo Rare cards, followed by the holo Nidoking, a Rare, and the holo Tyranitar, a Holo Rare. The surprise sits in 4th place: the Reverse Holo Psyduck, a Common, which outranks holos of far higher rarity. It is a variant slot rather than the card's main print, so the plain Psyduck tells nothing about what the reverse holo asks. Together the five hardest slots hold 19 percent of the master set's total value.

How the Aquapolis master set compares

At 349 slots, the Aquapolis master set runs about 1.5 times the era median of 226 slots among WOTC sets. By master set value it ranks 3rd of 16 comparable sets in its era, so it is a larger and higher-value job than most. Its neighbours are close in size: Expedition Base Set needs 344 slots and holds lower master set value, while Skyridge needs 343 slots and holds higher value. Of the three, Aquapolis asks for the most slots.
