These are the rosters we provide for unscored Intermission matches.
Champions marked with a * are secondary: they are available to that faction unless the faction they’re up against has them as a primary (no *) Champion.
We’ve tried to err on the side of broad rather than narrow Intermission rosters. Players are free to agree to restrictions ahead of the match: e.g., “let’s do a Piltover vs. Zaun match, with Zaun getting Janna instead.” Or you could say “No * Champions.” to limit rosters more to their core lists. Just make sure that everyone agrees ahead of time.
Note: Discord is a hybrid faction of the Shadow Isles and the Void. It probably shouldn’t be matched against either SI or Void, as there’d be too much weird overlap.
If you don’t mind, please take a moment to submit Intermission match results. No screenshot is required; it just takes a few clicks, but it lets me know about the activity.
