This setup allows you to create a legality checker for any custom Magic: The Gathering format, validate decks, and integrate seamlessly with Moxfield.

Hey everyone!

I just finished building a web tool to help validate Magic: The Gathering decklists in any custom format. It fetches card data from Scryfall, checks for banned or illegal cards, and gives instant feedback right in your browser.

It’s perfect for experimenting with niche formats, casual play, or even building decks for some existing formats like Standard Penny Dreadful, 2015 Modern, Classic Legacy, Pre Fire Modern, Pre Horizons Modern, Pre Modern. It can also integrate with Moxfield for deck building.

I’d love to hear your thoughts, suggestions, or ideas for improving it. Hope it helps deckbuilders and casual players alike!
