For more than 15 years now, one of my main GMing strategies when I run a D&D or Pathfinder campaign has gone something like this:
- Give the PCs the deck of many things.
- Wait for them to draw from it.
- Have fun with the results.
If I ever doubted that the deck of many things is the greatest magic item in the game, those doubts were dispelled at my last Pathfinder session.
