Why these cards lead the set
Gardevoir EX Secret Rare (#116) at ~$83 leads, with M Gardevoir EX (#112) behind it — Gardevoir’s collector base grew enormously after the XY era ended. Volcanion EX (#115), the set’s mascot, holds the #3 slot. XY-era secret rares had genuinely low print runs compared to Sun & Moon onward; clean copies are scarcer than the prices suggest.
