Grand Challengers Cup: format, rules and results

A store-level Bushiroad tournament series. Each official tournament store may run it once during October 2026, and entries go through Bushi Navi. It is for players with a ready-built deck, not a Sealed or Draft format. Always confirm details with the organiser before you travel.
