Staff members are drawn to the Magic Tournament as the locus of nerd-life at camp and they’re usually quite willing to help me with the fantastically menial tasks that dominate preparing my collection for sale. One particular staff member sprang to the opportunity to work with cards and I gave him the following directions: Create piles containing 12 unique cards of each color, 10 unique artifacts and 15 multicolor cards. Keep going until you run out of cards (he had a 5000 count box, which would take me almost a day to process).
I returned about 10 minutes later and he had make 12 piles each containing one card of each color, an artifact, and a multicolor card. He made 10 of these piles and when I asked him what he did he responded “I did exactly what you said”.
