Puzzle Time: Retrograde Analysis


You are a judge in a sealed deck tournament. Two players come up to you and complain that the other is cheating. they say that the other player drew one extra card. They each say that their opponent took a mulligan. However, they both agree on their life-totals and everything else about the board state. Since graveyard order doesn’t matter, both players have rearranged their graveyards. How can you tell which one is the cheating scumbag?

You quickly realize that it’s not possible to determine who drew an extra card from just that, so you ask a couple of players who were watching the match. One always lies, One always tells the truth, and the third one alternates between the truth and lies. You ask them all what 1 + 1 is , ban two people(Tina and Richard) for lying to a judge, and move on to your truthful man.

Honest Abe: I remember that Jake has never attacked Thomas, and neither player has ever discarded a card or shuffled their library. Oh, and one of the players mulliganned to 5 on the play, I just can’t remember who.

Now, everything becomes clear.

Who do you DQ ?
