A statement regarding the disqualification of a player from Pro Tour Modern Horizons 3.
Yeah this seems like an easy mistake to make. In fact, they were on coverage, which means they would have had a judge sitting there at the table with them, so the judge even missed it when it happened.
It's not like they don't know they're on camera, and on top of that, Van Etten was up a game already. Who would intentionally cheat in a situation where you're pretty much guaranteed to get caught, and you don't even need the advantage that badly anyway? The only thing I can think of is that Van Etten told the judges "Yeah, I realized it a couple of turns later but didn't say anything."
By the way, speaking as someone who's played my share of paper Magic and made more than my share of judge calls: call the judges when this happens. Their top priority is to fix the game state, not to punish you. Sometimes if the game has progressed too far to fix, they'll let the mistake stand. I don't know offhand how enforcement differs at a high-level event like this, but I think there's a real chance that Van Etten could have salvaged a match win out of this if he'd called the judges on himself in time.
@Evu @maino82 I mentioned this to my friend who grinds modern PTQs (or whatever they're called these days) and he said yeah that guy has a reputation for cheating.
Well, if he's cheated so much in the past that he can't get the benefit of the doubt from the judges now, he won't get a ton of sympathy from me either.
