It's more about having the connections to pitch to the right investors. I think people see a pitch deck as the answer similarly to the mindset of presentations in business (powerpoint), often failing to realize the pitch is the pitch and the deck is a supplement. A well crafted deck is to support a well crafted pitch, not the other way around. A lot of want-reprenuers I've met haven't learned this and think flashy decks are the answer to good old fashion salesmanship.
