Okay, so I'm 99% sure this is a silly question, BUT I feel like I played this game where the starting Deputy Mayor card starts in your Village, that is, built in your tableau.
However, the rules seem to be pretty clear that it starts in your hand. That is, you have to build it (and I'm assuming most people will tend to build it on their first turn).
So yeah. I'm pretty sure I understand the situation, but I can't shake a funny feeling that I should double check. So here I am.
It starts in your hand.
