Disciple

When played, the no-op option button displayed reads "Don't Throne"

[Ingix]

That's intentional, though debatable if ultimately a good idea.

Since Throne Room is the "play a card twice" card that most players are familiar with, "Don't Throne" is meant to tell you "Do not use the 'play a card twice' feature" in a short form.
