Deck quality scores is a huge problem, but you're absolutely right, it quickly bubbles out into exponential problem spaces. For example, even among a given Commander deck selected for a given matchup of `x` players, that deck list could have changed each of the last `n` games.

For this reason, the "assume a sphere with no friction" joke here is that deck selection, lock-in / mulligan processes, information asymmetry, and turn order, all being assumed to be equal and at that player's local maximum.
