Future IsoDom tournaments, should they happen, will officially bar use of DrHeld's point counter by all players. Use of the addon for tournament games, or refusal to turn the addon off, will be grounds for disqualification.
Specifics:
1. This includes matches between two players both using the addon, though I'll admit this is difficult to control. At least such a game is equal.
2. It does not matter if the point counter is set such that it can be disabled.
3. A screenshot showing the counter addon in use by the other player at the start of the first game shall be sufficient to disqualify the user. However, goodwill dictates that you assume the addon user simply forgot to turn it off, and the non-user is expected to request it be fully turned off, and start a second game. The user will be expected to resign from that first, erroneous game, so as not to adversely affect the rating of the non-user.
4. I won't change the rules mid-tournament for obvious reasons; this will only apply to future tournaments.
Edit: 5 is gone.
Edit: If the card counter is broken at some point in the future, all of the above will be rescinded, for what I feel are obvious reasons. I think it's necessary to clarify, though. As IsoDom originally was MMM's, he'll be given authority to use or not use these rules as he wishes.
You have been warned. Don't like it? Run your own tournament.
