Mewtwo EX and M Mewtwo EX headline BREAKthrough, the XY-era expansion of the English-language Pokémon TCG that released on November 4, 2015 under the set code BKT. It carries 162 official cards plus 3 secret cards, for 165 printings in total. Mewtwo EX is printed six times and M Mewtwo EX four, which gives the set a clear identity built around that one Pokémon, with Chespin, Axew and the trainer Brigette each appearing in more than one version. Psychic, Water, Colorless and Grass are the types it leans on most.
The pull ladder runs from commons and uncommons through rares to 24 Ultra Rares, with 2 Secret Rares sitting above the printed 162 and 26 chase-tier cards overall. The two Secret Rare Mewtwo EX cards, both illustrated by Mitsuhiro Arita, hold the top two spots by value, followed by two M Mewtwo EX Ultra Rares by 5ban Graphics, who also leads the set with 23 cards. A Mewtwo EX Ultra Rare by Ryo Ueda ranks 5th. The top five cards alone hold 56 percent of the set's total card value.
