What do you do when you have to seal cards when your influence deck is empty? Does this fall under lack of components, and as such, you skip it? Are you forced to shuffle your discard pile, but since it is out of the draw step, you don't have to suffer a distress or seal cards? Or is there another way this should be resolved?
And if it is my first suggestion and there is a choice (like when taking a shortcut on the dreamworld map), can you choose for sealing a card, even if you have none available?
