Riftbound players, lessons from a longtime MTG player; do not do this when cheaters are exposed, do not give them any grace, ostracize them. They are trying to steal hundreds of thousands of dollars in prizes from people, it was not a "coincidence" he did this in other rounds.
Lost vs this guy the round before, he had his hands under the table briefly. I didn't say anything as it didn't seem malicious, but to see this the round after sucks. Not accusing of anything, but he did come back from a very doomed game state. Hoping it's a coincidence :(
