So, you live in a world with magic. That's got to be pretty awesome, right? Wait, what?
Yes, you might be the one guy who doesn't have magic powers in this setting and have to find some way to make up for the disadvantage, you might not have developed your wizarding powers yet but know some killer sleight of hand that will put you up with the best for whatever deceptive reason you choose, or you might be that bastard of a con-man who needs to use stage tricks for part of a certain plan to achieve something that magic just couldn't do. Presenting the trope: there's real magic here, but illusion is being used.
Reasons for this can vary wildly, but usually it's done to either intimidate opponents into backing off or as part of some elaborate scam or con scheme. One particular scene which seems to be the favourite for Fake Wizardry employment is the climactic scene where the heroes scare off the big bad through elaborately-prepared stunts that make it look as if they have some insanely powerful form of magic (which they don't even though it exists).
Other times, a certain feat of über-powerful magic may be some big rumour that it's possible for the most studious or powerful of wizards to achieve. Naturally, some guy is going to either fake this to show off or for the more practical purpose of scaring his enemies/friends either away or into treating him like royalty. That super magic might even be legendary or prophetic, and the wizard fakes having it so that he will become The Chosen One.
If it's not done for benevolent means, expect it to be followed-up by the plot where everyone discovers that the wizard is a fake and the Aesop that they shouldn't fake advanced magic powers... except for those times when you should. (These times being when you're The Hero and... well, you're the hero, or if you're a slightly shady member of the good side who gets away with ends-justifying-means actions.)
Contrast Magicians Are Wizards, where someone with actual magical powers presents them as stage trickery.

- On one episode of Ojamajo Doremi the girls had a magic exam, during which they had to defeat other witches who obviously had many years of experience and vast numbers of spells in their arsenals. What did they do to impress them and win the competition? STAGE MAGIC TRICKS of course, and since the witches were so used to using real magic they didn't question if the magic was real. They assumed they were rare tricks even for them (like Doremi rotating her head many times).
- Played for Laughs in Miss Kobayashi's Dragon Maid when Tohru and Kanna mistake a spoon bending illusion on the TV for actual magic. They spend the rest of the chapter trying to learn how to do it (with a stereotypical martial arts training montage). It's not that it's more powerful than their own magic (Tohru is practically a full blown Reality Warper) but their pride as dragons doesn't let them accept that humans can do something that they can't.
- While Agent Esmerelda in The Big Four Cjupsher Series does know real magic and can be considered a member of the magical community, most of her magic are parlor tricks effective out of misdirection, something PH saw through instantly.
- In The Prince of Egypt, Pharaoh's priests rely on magic tricks to simulate magic powers. Obviously, Moses (via God) was able to do what they pretend to do and more.
- Willow: Willow is seen early on doing conjuring tricks for his friends. During the climactic confrontation with the evil sorceress Bavmorda, Willow claims to have magic powers beyond her comprehension and makes the MacGuffin disappear with one of his conjuring tricks.
- In Hocus Pocus Max is able to scare the witches long enough to flee with his friends by convincing them them that he has powerful magic. He does this by setting off the sprinkler system with a lighter, neither of which the witches have ever seen.
- Oz: The Great and Powerful: In the climax of the movie, Oscar "Oz" Diggs devises a plan that centers on making a big stage trick that the Wicked Witches will confuse for real magic. During the "final battle", he creates a fake apparition of himself with smoke makers and a projector (helped by the friendly tinkers) while claiming that "Oscar Diggs died so the great Oz could be free". Its scare tactic works greatly as, when the witches shoot fireballs at it, he appears to vanish but then reappears himself (because the tinkers turn the projector on and off by his command).
- Zig-Zagged in the Land of Oz. Magic is real, but the Wizard gets by on stage magic until Glinda the Good teaches him some real magic.
- Discussed in Magicians of Gor. Tarl and his friend Marcus hire a stage magician to steal a McGuffin; Marcus, like those of Gor generally, believes in magic and that the stage magician can do real magic. The stage magician assures Marcus that he will use mundane stage magic to steal the McGuffin rather than real magic, since it will be more humiliating for those from whom the McGuffin is stolen.
- There was a funny variant on this in the Dragon Lance series... during Raistlin's time-traveling tutelage under the Great Big Bad Evil Wizard Fistandantilus. At one point, he and several other apprentices are asked to demonstrate their magical proficiency in a room heavily warded with anti-magic - allowing them to rattle off the right incantations without actually blowing anything up.
That is, until Raistlin shows off by producing an actual fireball along with his incantations. Everyone is terribly impressed, since it seems like he's managed to break through wards set up by Fistandantilus himself, but as it turns out, it was all just sleigh of hand - he palmed a small alchemical firecracker and threw it to coincide with his spell. A skill hailing back to before he learned actual magic, when he practiced stage-magic for kicks. (Those skills also turn out to be very, very important later on, but that's another story.)
- In A Song of Ice and Fire the sorceress Melisandre definitely has magical powers, but they are weaker than she lets on, and so to maintain her image, she uses colorful powders, chemicals and the like. Making the stage magician connection is the fact that she literally keeps her "supplements" up her sleeves.
- In The Darksword Trilogy, not being a wizard is punishable by (sorta) death. Joram is taught sleight of hand as a child to escape this.
- The Second Apocalypse: Faking sorcery would be very difficult and dangerous, since the practice of magic is clearly visible to actual sorcerers, but that doesn't stop Anasûrimbor Kellhus from faking non-sorcerous "miracles". He regularly uses his analytical super-intelligence to appear to read minds or to prophesize future events. One of his more spectacular "miracles" comes when, in the middle of a vast desert, he points to a spot in the sand and tells his followers to dig there. When they do, they find a wellspring that saves the entire Holy War from almost certain death by exposure. Presumably he was able to detect the presence of an underground spring by some subtle cue, but to his followers it's obvious proof that he's favored by the God. (Of course, he becomes less reliant on deceptive tricks when he learns how to use actual magic.)
- Not stage magic proper, but at one point in The Malloreon a Grolim sorcerer uses a fake demon invocation plus an illusion spell as Step One in taking over a Karand kingdom. Belgarath counters with a fake invocation of his own and a far scarier illusion that sends the Karands fleeing for their lives.
- In the book Blood and Honor by Simon R. Green the protagonist is a down on his luck stage actor who uses stage fire magic to good effect against his opponents while posing as a mage prince with elemental fire powers.
- In one of The Tales of Beedle the Bard, a con artist poses as a wizard to fool a rather gullible king. And then a real witch shows up...
- Dragon introduced a Prestige Class for Dungeons & Dragons called the "Charlatan", which gains various abilities to fake magical powers, either through making spells cast through items appear to be cast by you personally, faking the results with alchemical items, or placebo effect.
- The Gates Of Hell: The game describes a devil named Byzine, who has several undercover identities, including a necromancer serving Orcus. Since he doesn't have a lot of necromantic magic at his disposal, he mostly relies on scrolls and such to create the impression.
- In Quest for Glory I, a large group of brigands are terrorizing the countryside, aided in part by a strange wizard. Hints are dropped throughout the game, however, that said wizard isn't really using magic, and in the end the "wizard" turns out to be the local baron's old jester, who has been using a mixture of intelligence, stage magic, blinding powders, and the rudimentary magic that even a non magic user can wield by knowing the right words or ingredients to mix together.
- Rise of the Tomb Raider: Lara encounters someone pretending to be Baba Yaga in the Wicked Vale level. Her apparent possession of sorcerous powers is made possible through the use of hallucinogenic spores that grow in the area and ransacked leftover technology.
- On Avatar: The Last Airbender we have the elemental benders, people who can manipulate one of the four classical elements (and the Avatar who can control all of them) and use them for Combat or everyday uses. However, not all people are benders, including Sokka, the Badass Normal of the Gaang. He has used some tricks to recreate similar effects, like bombs as fake firebending or using air pressure (provided by airbending, but the witnesses didn't knew that) to make rocks float on the air and pretend it's earthbending.
- My Little Pony: Friendship is Magic: Played with in the episode "Magic Duel". Twilight Sparkle, a magical unicorn prodigy, defeats her rival, Trixie (who currently was using an Amplifier Artifact of Doom to cast more powerful magic spells), by using a useless Magic Feather trinket and stage magic tricks to simulate even more powerful magic that Trixie was unable to do and fool her into taking off the Artifact to get the Magic Feather (and therefore removing her powerful magic amplifier).
- Thundarr the Barbarian: In the episode "Master of the Stolen Sunsword", Thundarr battles Yondo, a "wizard" whose powers turn out to all be fake and based on stage magic. Despite this, Yondo is a formidable opponent for Thundarr and company, giving them more trouble than many real wizards they battled.
- Young Justice: The first season episode "Denial" confirms the existence of real magic in the show's universe. The villain Abra Kadabra, however, uses advanced technology from the future to fake magical powers. Kadabra joins forces with Klarion, a genuine magic user, in hopes of getting bona fide supernatural abilities.
- The Amazing Randi is an accomplished Stage Magician who turned in his career to debunking charlatans who claimed to have paranormal abilities or psychic powers. Randi would show how their feats could be easily replicated using stage illusions, and challenge them to perform them in a way that would not allow for trickery, which, of course, they couldn't do.
- Harry Houdini similarly used his expertise in illusionism to expose phony mediums who used magic tricks to fake the manifestations of spirits at their seances. Houdini in fact believed (or wanted to believe) that communication with spirits was possible, but he was disgusted by frauds who used fakery to deceive vulnerable people.
- Uri Geller was a self-proclaimed psychic who gained fame for demonstrating telekinetic feats such as bending spoons on television. Skeptics such as Martin Gardner and the abovementioned James Randi observed that none of Geller's feats were ones that couldn't be replicated by magic tricks. When Johnny Carson (himself a trained Stage Magician) invited Geller onto The Tonight Show to demonstrate his "powers", but provided his own props that Geller wasn't allowed to have access to before the show, Geller demurred and said "I'm not feeling strong tonight."
