While resolving secret scripts, we have decided that you can’t do anything until the script is over. For example, if a secret script allows you to pay a shining gem to do something, but you don’t have it, then you are out of luck.
Is this right? Could you discard 3 cards to gain a gem? Or could you play a lightning bolt card to gain a gem? Or could you play a normal card to gain a gem? Use a mask?
