Zen and the Art of Ignoring Luck

Let’s envision a world where there is no such definition as luck and everyone understands and accepts the natural randomness of Magic. The local area hosts ten Magic players with skill levels that should assure a regular seat in the top 8 of any given PTQ that hosts approximately sixty people. If one were to trend the performance of these individuals over the course of several PTQs, the number of appearances of each individual in the top 8 should be approximately equal, with the occasional debut of a less talented player. Compare this with what you see in your local community. You’ve ascertained ten players to be of top 8 caliber. However, only four of those ten seem to follow your assessment and regularly star in the top 8. The other six are only special guests. What differentiates these two groups of players if it isn’t skill?
