I'd love an optional field on a card that allows you to provide a prompt. After the description, you have an italics/bold text that says something like:

When you use this card, you must describe how your overpowering strength helps you, but also some way in which you cause collateral damage.

This in combination with strong and weak outcomes would allow ppl to flavor their stories to taste. It is a way to use prompts to enforce style and tropes.
