The lesson
Put the end state of your story on the cover as a physical object, then spend the deck showing how it got there.
A Pitch Unfairly rebuild titled "RUNWAY". The cover shows a blue sweater tagged $12.99 FINAL SALE, with $148.00 and $59.99 struck through. Later slides argue "Blue is a category. Cerulean is a decision.", plot a five-step adoption curve with a falling price, and map an org chart: "Six rooms chose your sweater. You were in none of them."
Skip the fashion topic and the figures, which belong to the story. Keep the recurring object whose value changes from slide to slide, and the headline that states the thesis in one line.
