The rules can't do anything about it! I myself twice ended up in situations where I used 2 Dimension Doors in important tournament games "in the heat of battle," so to speak (once on Jebe and once on 8MM6, where only one Dimension Door was allowed). Such restrictions must be implemented functionally, at the code or text file level. A player very often breaks rules without suspecting it and without any intent. And these violations are not the players' fault—it is all due to what was rendered on the map with bugs. If I see a passage and can go there, then I go there, regardless of whether there should be guards or not... spare me from these reflections by rendering the map correctly. Make it so that I cannot break the rules, but only play. Because players' responsibility should be adequate—and not at the cost of the match (for example, introduce a point-based result system, 0.7 to 0.3 instead of 1-0, or introduce "-0.1" for no-shows).
