Supreme Victors marked the final main set of the Diamond & Pearl era, arriving in 2009 as a celebration of powerful Pokémon across multiple generations. The set captured collectors' attention with its focus on Level X cards—the format's answer to competitive evolution—and represented the last major release before the HeartGold & SoulSilver transition. It remains a nostalgic touchstone for players who experienced the mid-2000s competitive scene. Rayquaza C lv. X stands as one of the set's marquee attractions, featuring the legendary sky guardian in its most formidable form. The Level X mechanic allowed this Pokémon's raw power to shine through, and the holo treatment brings dramatic presence to the card's dynamic artwork. Collectors seek this card for its iconic subject matter, competitive significance during its era, and visual impact.
