I've recently stumbled into 'whimsy cards' on several occasions and I have a growing curiousity about them. That I don't know much about them only goes to show that I'm a newbie who've only been around since 3rd edition.. Now I know that they can be found on various subpages to the Redcap and I know Tuura once did a fine introduction to them (here). But I'm really curious to hear more about the whimsies! Anyone using them? What's you experience and attitude toward them?
And while we're at it I would really love to know about other forms of 'formulaic' narrative tools that anyone are using!
