Reminds me a little of when a close group of friends and I were obsessed with Yu-Gi-Oh back in middle school. At sleepovers, we'd constantly duel each other for hours and refine our decks to no end.

To make it "more fun" (at least, from our perspectives), we'd do a limited kind of sorting on our decks before each game and stack the decks in the pattern "monster, monster, non-monster" so that even after our opponents shuffled our decks for us, they'd still be in a relatively optimal configuration.
