Affectionate Parody: Net Movie Kamen Rider Wizard in Magica!? Land, a series of Web Videos created to promote the film. Parodies Wizard, it's characters, and the entire Kamen Rider franchise.
Alternate Self: The Land of Magic contains versions of all of Haruto's friends, and some of his Phantom enemies. At the end of the film, Shiina and Maya the Great are seen in the real world with their families.
False Utopia: Initially the Land of Magic seems like a better world; there are plenty of other Kamen Riders who can fight Phantoms, and even Beast doesn't need to eat Phantoms to survive. The entire reality was constructed just so Kamen Rider Sorcerer could tear it all down and turn every human into a Phantom.
Funny Background Event: There are quite a few scenes with some magic-related event going on in the background.
Gadgeteer Genius: Magic Land's Nitou deserves credit, since in this reality he invented the Beast Driver rather than simply finding it.
Grows on Trees: At one point Haruto finds Nitou fishing...for mayonnaise. When he expresses shock, Nitou asks "What, does it grow on trees where you come from?" complete with Imagine Spot.
Laser-Guided Amnesia: Only Haruto and Koyomi remember the old world, and their friends don't remember them.
Living Battery: Kamen Rider Sorcerer abducts victims in order to create a battery that can store magic - specifically, the magic used as currency. By reversing the polarity, the battery can also be used to turn mages into Phantoms.
Mundane Utility: Magic in the Land of Magic. For example, a mother uses the Connect spell to grab her unruly child.
