Q: What does it mean on the ‘Oath’ objective cards when it says to reveal them?

A: If you wish, at the start of your first activation in the action phase, you can reveal any ‘Oath’ objective cards to your opponent. This means that you show those cards to your opponent – you should give them time to read the card or cards in their entirety if they wish. Once they are satisfied, return the card to your hand, concealing it once more from your opponent
