Actually, Yu-Gi- Oh! was originally intended to be a puzzle , or rather, a toy , like the Millennium Puzzle ...
But I think it's clear that what made Yu-Gi-Oh successful was the trading cards ... 😟
I think the key to its success is that it didn't set out to be a manga about puzzles right from the start .
In other words , without deciding on a specific direction for the story from the beginning , there are only characters and a vague ,
Also, incorporating the latest topics at the time, and a loose, tightrope- walking kind of manga might be better suited to serialization.
Also, inflationary battle manga , where ever stronger enemies appear , can go on forever .
Just when you think the universe will be destroyed and the end will come , a new Big Bang occurs and another world is created .
New characters will be available, and it should be possible to revamp Motorhead beyond just Gothic Maid ...
