I Seal Worlds Into Cards

Dying to save another was supposed to be the end. Instead, he was reborn into a brutal interdimensional game where survival is the only prize. Thrown into shifting realms of magic and mayhem, he awakens a unique power: the ability to seal any creature, weapon, or skill into a mystical card. As he builds his deck, he must also build a team, battling rival players and monstrous threats. But he holds a deeper secret—he is the chosen vessel for the game's godlike architect, granting him access to a terrifying power that comes at a devastating cost. Now, he must master his cards and his fate, climbing the ranks to uncover the truth behind the celestial throne and find a way to protect those he holds dear in a contest designed to break him.
