Mewtwo EX is the name that defines BREAKthrough, with Mewtwo EX and M Mewtwo EX together taking ten of the printings in the card list and holding the top spots by value. This English-language Pokémon TCG expansion belongs to the XY era and series and was released on November 4, 2015 under the set code BKT. It has an official count of 162, with 3 secret cards above that, for 165 catalog printings in all. Psychic, Water, Colorless and Grass are the Pokémon types it leans on, and Chespin, Axew and Brigette also appear in more than one version.

BREAKthrough is part of the XY era.
26 cards in BREAKthrough sit at one of its hit rarities. See this set's hits page for the full breakdown by rarity.
BREAKthrough's rarity ladder runs from commons and uncommons through rares to 26 chase-tier cards, made up of Ultra Rares and Secret Rares, with the secret cards numbered above the printed 162. The most valuable cards are two Secret Rare Mewtwo EX printings illustrated by Mitsuhiro Arita, followed by two Ultra Rare M Mewtwo EX cards from 5ban Graphics and an Ultra Rare Mewtwo EX by Ryo Ueda. The top five cards alone hold 56 percent of the set's total card value, so most of what makes these chase cards worth chasing sits in a handful of Mewtwo pulls.
As of October 2026, BREAKthrough holds the 7th highest total card value of the 14 comparable XY sets, about equal to the era median, and its top card ranks 8th among the era's most valuable single cards. It is 6th for trading activity in the era and 80th for total value across the whole game. At 162 printed cards it is larger than the era median of 113. It followed Ancient Origins, which holds more total value, and came before BREAKpoint, which holds less. Its cards first appeared in the Japanese sets XY8-Br: Red Flash and XY8-Bb: Blue Shock, released September 26, 2015.

A complete BREAKthrough run is 165 catalog printings, and all 165 are priced. Because the top five cards carry 56 percent of the set's total value, the cost of a full set is driven by the Mewtwo EX and M Mewtwo EX chase cards, while the large base of commons, uncommons and rares is a smaller share. The sealed line has 34 products, including a booster box, Elite Trainer Boxes, Premium Collections, blisters, decks and booster packs, so there are several ways to open the set.
