BREAKthrough Master Set Checklist & Cost

Variants in the BREAKthrough master set

Three families make up the BREAKthrough master set: Reverse Holo with 137 slots, Normal with 123 and Holo with 42. The reverse holo family exists because Common, Uncommon and Rare cards each have a reverse holo print alongside the regular one, so every card at those tiers takes two binder slots. Holo slots belong to the cards printed only with a foil finish. No stamped or special-edition families appear in this set, so a complete BREAKthrough master set is mostly a matter of finding every card in both of its standard finishes.

Where the BREAKthrough master set's cost sits

The BREAKthrough master set cost is heavily concentrated. Its ten most valuable slots hold 60 percent of the total value, and the holo finish alone carries 75 percent, with reverse holos at 20 percent and normal prints at 5 percent. The lower-value half of the priced slots adds up to just 3 percent. Of the 302 slots, 302 carry a price as of October 24, 2026. Condition matters a great deal here: an LP and up master set sits 39 percent below the Near Mint total, and an MP and up set sits 60 percent below it.

Hardest BREAKthrough master set slots

Five slots, all Mewtwo EX cards in holo, define the difficulty of the BREAKthrough master set. The two Secret Rare Mewtwo EX slots rank first and second by value, followed by the two Ultra Rare M Mewtwo EX slots and an Ultra Rare Mewtwo EX in fifth. None is a variant of a card's main print, so every one is a straightforward chase card rather than a hidden reverse holo surprise. Together these five hold 44 percent of the master set's total value, which means the rest of the checklist is comparatively quick work once they are in the binder.

How the BREAKthrough master set compares

At 302 slots, the BREAKthrough master set is about 1.4 times the XY era median of 209 slots. By master set value it ranks 7th among the 14 comparable sets of its era. The previous set, Ancient Origins, has 173 slots, yet its master set holds higher value than this one. The next set, BREAKpoint, has 222 slots and a master set of lower value. So BREAKthrough is a larger master set than either neighbor by slot count, while its value sits in the middle of the era.
