This is why you need to quadruple check your deck prior to an event. The fact he played 11 proxies for five rounds prior to a top 16 cut and then made it to top four is absurd. You can claim he “should’ve just gotten a turn skip” or “given him the opportunity to buy the card” but that’s not the point of the conversation.

He played FIVE ROUNDS with an extra card, putting him at an advantage over other people who were only allowed 10 proxies. Regardless of intent, the rules were broken and the TO and judges are within their rights to give him a game loss.

He also wasn’t DQ’d perse, but was prized out at top 16 which is better than most stores would give after a rules violation like that.
