A concise one-page move/procedure slottable into any game. The reverse side of the page gives background & summarises the main points of the linked pamphlet.
While I generally prefer some randomiser element, this is a great framework that lets magic be powerful & impactful, "balancing" it against player consensus (two other players have to be on board with your proposed effect) and against possible consequences for your character and the world.
Really nice job. Would work equally well in a game where everything is freeform and negotiated, or in a game where everything else "mundane" is handled by hard rules. e.g. a Star Wars game where the Force retains a sense of mystery, rather than being a laundry list of superhero powers.
