- This format features the first (and thus far only) early rotation in the Pokémon Trading Card Game's history. This likely came about in response to the heavy controversy surrounding Black & White's first-turn rule in the previous format, with cards like Sableye creating a metagame that many players felt was too unbalanced and luck-based to be at all enjoyable.
