A: The game goes until either “side” needs to draw a card, and can’t. So if the Rule deck draws and plays its last card, that’s fine, the game continues. If the player can draw ALL of the cards they need to, they can start their turn.

It’s possible that something they do will require them to draw more cards mid-turn, of course, so they might not be able to complete their turn, but they might still get something done before that happens.

So hold off on that D3P2 if it’s going to end the game but you still have things you could accomplish!
