… The rules say I can choose not to change the Silver Dragon color (as long as this isn’t the first Action played in the game) by putting it on the bottom of the discard pile. It also says I can choose not to use the Action’s power. Can I do neither?

A: You may not play an Action card to no effect whatsoever. Passing is an option if you don’t want to do anything, but you can’t waste an Action card. If you play it, at least one of the actions it provides must occur.
