This is a world where Soul Card Masters control Soul Cards in battle.
At first, everyone dutifully built decks based on card abilities and summoned higher-ranked creatures. Then Yu Cang awakened the Keyword Recorder, and the whole world's vibe got weird.
From high-tier decks and dangerous secret realms to a dream or an event, anything can yield a unique keyword, which can then be used to build Soul Cards!
Your Jedi won't take any healing? Just slap on a “Firefly Grass” keyword to trigger a chain effect and slowly restore its health.
You got a top-tier fire dragon card, but your main deck is water-element? Easy. How about trying this “Water Storage” keyword?
What? The summoning requirements for the Alien Star Radiant Dragon are so demanding that it's nearly impossible to use in a solo fight, making it a Soul Card meant only for war?
Well... how about Ritual Magic? Or just extract the “Alien Star” keyword and build a deck specifically for it!
Your spell Soul Cards can't establish a board and can't defend against enemies right in your face? The “Eternal” keyword turns them into cannons in an instant. Blast them to bits with an endless stream of fireballs!
Facing a swarm of monsters and can't break through? Just add the “Echo” keyword and show them textbook Profanation!
“I've never seen a card maker like Yu Cang. Have you ever seen a Soul Card whose ability description alone takes three pages? His whole hand is full of cards like that!”
And it all began when Yu Cang was bullied in academia.
