Champions League 2027 Yokohama, one of Japan's flagship official Pokémon Card Game tournaments, ran September 20-22, 2026 at Pacifico Yokohama, played in the current MEGA-series Standard format — the same format anchoring the September 16, 2026 worldwide launch of the 30th-anniversary set "30th CELEBRATION."

This Pokémon Center deck shield features Gwynn and Mega Chandelure from that same MEGA-series lineup, via CDJapan's Proxy Shopping Service.
