Dueling Club?

Can "magic duel" please be added as an available activity for clubs? I want my club of spellcasters to duel each other at club meetings. Making "cast spells" a club activity isn't the same - I don't want them setting fire to my house or burgliating my stuff. We can ban mischief social interactions, but not mischief in general, so I don't know how to set it up to encourage normal friendly spellcasting like scruberoo without encouraging mischief magic. Actually being able to ban all mischief and not just mischief socials would be great, but that still wouldn't get them dueling, so I need "magic duel" as something to add as a club activity anyway.

If I had a club of vampires, "vampiric sparring" would be the equivalent there.

Thank you!
