How can I play with custom MTG format with a shared card pool to check for legality?

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?
