This is a pretty basic flask api that returns older yugioh banlists in JSON format (since I needed such thing but didn't find so I made this), the banlists data was scraped from yugipedia then stored in MongoDB
The most challenging part is that I made this in my phone (the only hardware I have), that prevented me from making a UI and improving the project in general
I think there wouldn't be so much yugioh players here, if you are I hope you like it and find it useful, otherwise you can give me feedback about the technical parts and stuff...
