I'm looking for a novel where cards is major plot point or weapon. If I were to give an example, something similar to the Greed Island Arc of Hunter X Hunter.
Monster Paradise Summoning the Holy Sword Divine beast adventures (on Webnovel, not yet translated though)
Godly Model Creator They use the word card, but it’s not like playing cards, I think (read only like 150 ch or so, so not too sure)
Yu-Gi-OHHHHH~ please stop nya! NO! NO MORE NYA! I CANT TAKE IT NYA... Don't call anymore cards AYA!!! I CAN"T TAKE IT NYA!! I'm gonna die! I'm GONNA DI--- *eyes rolls backwards*
