I also thought up of another something that I will not edit into my other post.
Let us assume that the Tournament Organizer himself is participating in the tournament. I am not saying that the Tournament Organizer is cheating or anything, but, a completely different thing.
TO is in the quarter finals (Not that hard to do with the low amount of people in tournaments these days.).
TO won his match, checked his (?) and his opponent deck.
The player B in the same blockside of his brackets won his tournament.
Player B will fight TO in Semi-finals.
Is it fair to make Player B send his decks to TO before they fight?
If Player B used an illegal deck against player C ( The one that lost before TO and player B fought), that is, again, unfair.
If player B sends his deck to the TO before they fight, it is common sense to assume the TO is going to tweak his deck so that he does not lose. Not changing your deck and going with the losing one would be an impractical option in this case; therefore giving TO's an unfair advantage.
This means that, as to avoid even further disruption by these rules, the TO must not participate in the tournament.
This rule is really not needed and has several exploiting points. It seems, I.M.O, to be a poorly handled rule when in practical action and easily avoidable either way. There is no way to know if someone is unintentional or not. I would also like to add that, if a player used an illegal deck the whole tournament ( blarp... ) to a point that he won, it is obvious that it is a disruption of the tournament as several people will be angry they lost to an illegal deck and don't have a way back. I'm still surprised blarp received his 2nd place code and, worse, didn't even get a ban from the next week tournament from "cheating" (unintentionally) and disruption... which are also stated in the rules -- Much more clearly than our current 3.7 rule.
