I want to play a custom MTG format where the card pool is defined by a Scryfall search and updated twice a year. For example, my search might be f:standard f:penny usd<=1.
How can I export, share, and import the list of legal cards with other people so that we can all check card legality and use a deck builder with the same pool of cards?
If you do a Scryfall search the URL will match the parameters of the search. So you can just copy and share the link.
Scryfall will update Standard/Penny Dreadful rotation and price as it changes, so the list will always be current.
The list needs to be static. How can you create decks for a format that is constantly changing? What I need is a way to share a consistent list of legal cards so that everyone can search within the same list, rather than each person having a different version.
