A list of every ladder with check boxes that you can toggle to add yourself to a backup queue. It would work like this:
If someone tries to search for a game and no one else is on the ladder, Showdown sends a notification to every player who is currently online, not in a match, and has that ladder toggled for backup queue, asking if they would like to join a game on that ladder. If they say yes but someone else has already joined the battle first, the notification could either just disappear or redirect you to searching for a game in the normal queue… whichever feels more intuitive.
Not only would this do a lot to combat the problem of dead ladders, but it would also encourage users to spend more time team building, so as to have reliable teams ready in their favorite ladders, as well as to experiment with formats they otherwise wouldn’t bother building for since it’s so hard to queue up a game.
