When I design gameplay rules I often use comic strips to capture the essence of the rule. By 'essence' I mean, the important element of the rule. For example this comic strip shows the rule of metamorphosis. When the three monsters (Brown, Orange, and Gray) step on a certain metamorphosis-box, they will shape-shift. One of them will shape-shift to be Antler Ancestor and the other two will be little flies. They follow Antler Ancestor around, wherever he goes. When all three are close enough to each other the transformation goes back to three monsters. See, it's so much easier to convey all this information in a comic strip.
