The point of my last post is that most rulings are investigations. It’s not because you think one of the players might be cheating that you investigate – it’s the other way around. You investigate in order to fix the game, and occasionally you might stumble across a hint that a player is cheating. But the vast majority of investigations are just that – finding out what happened.
The Mystical Tutor team made a very interesting presentation on this topic that I encourage you to study. Credit goes to Dustin Jones, JP Adams, Jeff Emery, and Jared Sylva for this seminar, thanks a lot!
