I´m paying an action card that has '0' gold cost listed.
That '0' means 'zero' or 'no cost'?
If it´s zero, could I pay gold to make possible to use another card effect that can only be played after I pay the cost of an action?
For example, I play 'Draw Your Blade', and pay 2 gold even if it´s listed as '0'. Can I do that?

Zero. Yes, you can overpay.
