Possible Cheating Scenario
For those advocating DQ for fraud, what rule did he break? He failed to utilize an optional trigger. He was not going to get the effect of that trigger after the time the trigger was supposed to occur.
I agree, his intention was to cheat. However, he did not commit a violation. He called a judge, and he had hoped/planned that he could get the trigger effect at that point. If the rules supported this (which they haven't for a very long time (ever?), due to the ‘may’ clause in the Tamiyo emblem), then we would absolutely have a DQ situation on our hands.
So we have a player who called a judge, hoping for an outcome that would be cheating. However, that outcome could not occur under the rules, so the cheating does not occur. Basically, he thought he was violating a rule, but did not actually do so. I don't think we can consider administer a DQ here, as much as we'd like to.
I would recommend a USC-Minor penalty, as his actions (attempting to cheat, resulting in an investigation) were disruptive to the tournament, and this also documents his behavior in the penalty database.
