Custom formats now show a Scryfall link on their tile

Official Magic formats have always had a quick Scryfall link right on their tile in the Formats catalog, so you can jump straight to browsing the legal card pool. Custom formats now get the same shortcut. Every custom format's tile shows a Scryfall link built from its actual set pool and any individually added cards, so you can check what's legal before diving in, no need to open the format first.
