BREAKthrough (2015) marked a pivotal moment in the Pokémon TCG's modern era, introducing the BREAK mechanic that allowed players to evolve their Pokémon in entirely new ways. Released during a period of genuine competitive renewal, the set brought fresh strategic depth to tournament play while maintaining broad appeal to collectors. Its robust card pool and reprints of beloved Pokémon ensured lasting relevance across multiple player generations. Float Stone exemplifies the utility Trainer cards that formed the backbone of competitive decks throughout this period. As a tool card that granted free retreat ability to equipped Pokémon, it saw widespread play and remains instantly recognizable to anyone active during these years. Reverse holos from BREAKthrough are particularly valued by collectors seeking the set's complete subset variations.
