BREAKthrough checklist

BREAKthrough lived up to its name in late 2015 by introducing a whole new card type: the Pokémon BREAK, printed sideways in shimmering gold as a new way for Pokémon to evolve. It's a huge set, over 160 cards, and its biggest chase is the Mega Mewtwo-EX, one of the most powerful and collectible Megas of the era. Between the new BREAK mechanic and the sheer size, it's a landmark XY set and a big one to complete. See how close you are below.
