Surprised this hasn't been mentioned.
I just got around to watching this and in one episode Wednesday and Morticia decide to settle a thing via a (UF-style) Rose Duel.

The show does call it something else, they're doing it _blindfolded_ and it features glass heart brooches instead of actual roses, but it's unmistakably a Rose Duel of the sort that Kate & Utena get up to in the later seasons of SoS.
