Halloween // “Magic” themed costumes?

Hello! Per title, I’m going to an event soon and the costume theme is “magic.” My boyfriend is going as a Magic 8 Ball, and I would love to go as a something similar, potentially fortune-telling adjacent? My brainstorming yielded an Ouija Board, a “cootie catcher” (apparently that’s the name of those little origami fortune tellers we’d make in elementary school?!), a fortune cookie, etc. Is there anything else obvious I’m missing? Or just a cute idea for “magic” that is unique would be great too (assuming there will be lots of fairies, witches, Harry Potter characters, etc.). Thanks in advance!!
