I don't have a name for it, but I really like this idea! Oscar's semblance seems to parallel Jaune's in that it'll likely be unlocked in his 5th volume in the series, so I think it might tie in in a really creative way to the fabled Wonderland Arc or "Other World" theme of volume 9. Gotta post this before the finale, so enjoy this little late-night theory, and sweet dreams ;)

Time for me to go to bed
