What are the benefits of having a large number of slides in a deck?

Apart from using superb slides, other ways to present in front of a high-stakes audience include: practicing your speech thoroughly, understanding your audience's needs and expectations, using compelling storytelling, incorporating relevant data and statistics, using appropriate body language, and engaging with the audience through questions or interactive elements.

There are several other slide decks that have a sophisticated feel. Some of them include the 'Business Pro' deck, 'Corporate Overview' deck, and 'Annual Report' deck. These decks are designed with a professional and sophisticated aesthetic, making them suitable for high-stakes presentations. However, it's important to note that the sophistication of a slide deck also depends on the content and how it's presented.
