While Others Make Cards, I Seek Core Fragments: One Card Shocks the World

A genius falls from grace, abandoned by everyone, all because I awakened the strongest profession yet spend every day crafting “trash cards.”

My childhood sweetheart left me for the upper class.

My family was utterly disappointed in me; only my younger sister secretly helped me out.

Everyone called me crazy, but I knew I was waiting for an opportunity.

When millions of cards came together to form a special deck-building logic

[Ding! Core card [Joker] activated!]

[Ding! [Multiplication] effect triggered. All attributes have increased exponentially!]

From this moment on, the tables have turned!

You'll pay back everything you took from me, with interest!

Those who looked down on me will kneel and look up at me!

They grow stronger by relying on the rules, but I am the rules themselves!
