There has been some discussion on The Mana Drain and other places about some of the on and off camera behavior of the winner of Eternal Weekend, Joseph Bogaard. I have cataloged the evidence in what I hope is an objective way, although I suspect that my conclusion is evident. Where possible, I have provided a timestamped link to Twitch VODs with a short explanation of what I am documenting.
From the Swiss:
Kurt Crane versus Jospeh Bogaard in Round 7:
Playing 2 lands in one turn and not announcing mana drain trigger:
Playing 2 lands in one turn:
9 cards in hand after forgetting to discard (this one requires a couple minutes of watching):
I am not 100% sure what is going on in the last link, but that is 3-4 GRVs in a single game.
One of Joseph's opponents during the Swiss called a judge. The complaint was that Joseph's sleeves were marked in a manner not consistent with normal play wear. The judge did not notice anything, but Joseph's opponent was not confident that the judge knew what he/she was looking for when inspecting the sleeves. An appeal was not made (presumably because his opponent was not aware of the pattern of behavior).
From the Top 8:
I was a firsthand witness to the events which I am documenting from the top 8.
Randy and Bob talking about the "sketchy guy" on live mic:
(I will delete this link if Randy, Bob, or Nick Coss think it is inappropriate.)
As Randy and Bob mention, Andy and Joseph were deck checked after presenting. Most of the way through Joseph's shuffling procedure, he performed a very strange looking 5 card pile shuffle, in which he did not place cards in a loop, but each time around put cards into piles in a different order.
Confirmation of 25 minute deck check:
After an extensive conversion with the judges, Joseph received a warning for insufficient randomization.
Appearance of warped foil sol ring, crucible of worlds:
After game one I noticed while they were sideboarding that Bogaard appeared to have only 4 foils in his deck: FTV Strip Mine, Judge Sol Ring, Non-Judge Foil Crucible of Worlds, and Snapcaster Mage. The first 3 foils are notable for being the versions with the most foiling which causes them to warp. They are also notable for being the 3 cards available as a foil that you want against shops.
Moreover, from what I could tell he was playing a single sleeved deck, which would make foil bending more apparent. A fellow spectator relayed this to the head judge. From what I could tell, the judging staff made Joseph take out his foil sol ring and crucible of worlds, but they waited until after he won against Andy.
If this is true, there is a dangerous lack of logical consistency. If the cards were marked, Joseph should habe received a game loss/DQ (much like people who had marked delvers in Champs two years ago). If they were not marked, he should not have been required to switch out his cards.
Evidence of Sol Ring being switched out in his semifinal match:
Joseph's method of pile shuffling here is roughly what I was talking about from his quarterfinals match. If I recall during the quarterfinals presentation he changed his method of deciding which stack to put cards in more:
When Joseph stops riffle shuffling his deck, he is receiving verbal instructions from the judge to adjust his shuffle technique. As pointed out below, the same few cards may be floating at the bottom of the deck after several shuffles because he is not riffling cards into the bottom:
Shortly after this game started I stopped watching due to frustration.
Taken in isolation, no single one of these incidents would lead me to conclude someone cheated at Eternal Weekend. Taken together, one might be lead to a different conclusion.
Note: I have omitted naming anyone other than as necessary.
Final Note: It was difficult for me to post this. I have the utmost appreciation for Nick Coss because of the time and care he puts in running these tournaments. I do not wish to harm his future Eternal Weekends with this thread.
