Walpurgisnacht is a particularly tough enemy from the Madoka Magica collab. This is because her falling building attack can destroy lots of cats at once and slow down any survivors. Her area of effect is tremendously wide as well. Also keep in mind that she is not a Floating enemy despite being in the air.
Surprisingly, this enemy becomes very easy to beat if you have unlocked both Li'l Madoka and Li'l Homura and use them in battle. The Cat Combo called My Very Best Friend involving these cats will further improve the effect of their Witch Killer ability by a massive factor. You can use also any of the Uber Rares from the collab (Madoka, Homura, Sayaka, Mami, Kyoko, Bebe) since they have the same ability.
Without Witch Killers, the battle becomes more challenging, as weak or low-leveled cats will die in the process before being able to deal significant damage.

Trivia
Walpurgisnacht is tied with Homulilly for the 2nd place of most abilities out of all enemies. The only other enemies with more abilities are Variety Bears and Awakened Eva Unit-13, both of which are also tied.
Walpurgisnacht is also the name of a German holiday. Walpurgis is a celebration commemorating Saint Walpurga starting on April 30th and ending on the 1st of May, while Nacht means night in German. Walpurgis is commonly associated with religion and celebrations and, like many things that are associated with religions, also with witchcraft.
Walpurgisnacht was far more powerful during the original run of the Madoka Magica collab in the Japanese version, boasting tremendous attack power.
