Kaku-San-Sei Million Arthur

About

Kaku-San-Sei Million Arthur is a deck-building RPG where players select a hero and gather cards to strengthen their team. Progress involves battling bosses and rivals, earning new cards and resources to upgrade or merge units. Each card can level up or evolve through combinations, unlocking stronger abilities called Limit Breaks. The goal is to craft a powerful deck to dominate competitive battles and rank as the top Arthur. Available on Android, iOS, Vita, and 3DS since 2012, the game’s servers have closed on most platforms leaving only offline play. Despite its age, the card mechanics and progression systems remain a focus for strategy fans. The mix of single-player challenges and old-school multiplayer options shows its roots in early 2010s mobile design.
