Yo Blunder, have you ever thought about doing a 'Guess that elo' type of series? Viewers can send in replays (and their elo under a spoiler tag if it's not in the replay) via Discord or so and then you can watch them and guess their elo based on what you saw in the replay. You could do it together with people like CTC, Sama or Joey and have a game with points awarded to the person who was closest to the correct elo.
