Lyssa is associated with beauty and is the patron of many artists, especially actors, so I THINK the sisters could improv almost anything and would be most likely win. Plus as a bonus Lyss and Ilya could use each other as dance partners. Balthazar would probably do something like an NFL touchdown dance, Dwayna would be a graceful dancer but Grenth would probably leave soon after because MOM DANCING, Melandru is a tree and Kormir would just be ????? is this how we solve disagreements really this is what we go to what i have i gotten myself into??????
Though serious answer: Abaddon returns and serves everyone
