Earlier today I was watching a Magic streamer on twitch who said they are going to be going to a SCG/GP event this weekend, and that they had a bet with another streamer/Magic player who was going to this same event.

Being that these two people are friends, the wager was that the person with the worse record at the end of the event would have to buy dinner for the winner.

If a HJ heard about this wager would they be correct in disqualifying both competitors? Why or why not?

While this does seem like a corner case scenario I could believe it occurs more often than we would like it to.

Players have been DQ’d for almost this exact thing.

Generally, we never hear about these “friendly wagers” - but this does violate the rules.

Perhaps contact the streamer to let them know this behaviour is not OK. It would be even better if you would manage to convince them to publish the lesson learned and educate their subscribers (who are now thinking that wagering is OK).
