Majo no Atsumari is pretty succinct as-is imo. Although looking at it atsumari is a bit... odd. As in it looks like a verb as opposed to a known. You could try 集会 shūkai, so Majo no Shūkai, or even just Majo Shūkai would work.

"Majo" (魔女) is literally just the kanji for "devil" and "women" taken together as one word, so you could also play around with the actual "witch" meaning. 魔術師, majutsu-shi "conjurer," 妖術者 Yōjutsusha "sorcerer", 手品師 "tejinaji" (more for slight of hand card trick "magic"). There is also 巫師 miko-shi and 祈祷師 kitō-shi, "shrine maiden" and "master excorcist" respt., which is what I got for "shaman"
