I've never smelled a pitch deck but I'd say absolutely yes. The team section isn't just a rundown of precious startups - it's you. What have you done, built or hacked that shows these people you're someone who gets things done/they can trust with their money. It's all part of the story - what can you tell them that they'll remember & be impressed with that ties into why this idea, why you, why now.

If you're thinking about not including it due to lack of confidence, that's a mistake.
