Oh yeah, I think it's clear there was zero intent to cheat. He just filled his deck list out wrong and followed it to the letter. But as it flipped over and Nick just kind of motions over to it had to be hilarious in person. I guess add that to the reasons not to just scoop to Griseloath.
#2 Deck Reg Error
DFR and Coss are friends, with David frequenting the monthly Vintage events at Nick's store, so I'm sure they were able to laugh about it together. Dave had mentioned to me the day prior that he never wins his on-camera matches, so he was probably ready to do more of the same. Funny enough, the turn he won during game 3 the stream cut out, so afterwards I went over and told DFR that he still hasn't won on stream, which he got a kick out of.
Northeast Vintage really is getting paired against your friends every round, which can still be true even when the event is 95 players deep.
