I agree that's suspicious but again it's one persons word against another's. If it makes somebody feel better to cheat in order to win a casual wall game of magic then so be it. I honestly feel sorry for them if that's the case. I have my integrity in check and really bare no ill will towards the sad little people who need to cheat in order to feel accomplished.
I doubt milo or anyone else cheated. Like this wise man said ^, why would someone cheat on a wall game with no prizes? What gain would anyone ever feel from that?
"wow I just nailed someone hard online because I made a fake deck and picked my opening hand. Yep...I'm such a bosser!"
Just doesn't sound right. that doesn't mean cheating didn't happen. Nobody can prove it. But don't accuse. Just don't play that person if you think he or she cheats. Honestly if I cheated at a wall game I would say to myself at the end: "hmm, I just wasted my own time. I didn't get any better, abd I wasted someone else's time too. I'm such a loser!"
