Nemo and Ahab are playing in the second to last round of a GPT at which you are the only judge. Their game is near its end, with Ahab at 3 life and Nemo at 1. Ahab controls an Invisible Stalker and will be able to attack for the win on his next turn. During his own turn, Nemo is tapping lands in preparation to cast a spell when Moby, a player who is done with his match and is standing behind Ahab, says, “Wow, I didn’t know they made a textless Negate!” Moby then gets a horrified look on his face as he realizes his mistake, but the damage is done. As you assess the situation, you notice that Nemo has only two cards in his hand, Mountain and Demonfire, and that with the information he just gained, Nemo will know to play his land before the Demonfire and win the game.

What infractions have been committed, and by whom? What is the proper penalty for each of those infractions? And finally, how do you rectify the game state now that Moby’s comment has surely altered the outcome?

Judges, feel free to discuss this scenario here!
