I played Magic: the Gathering for years, about 2013-17, and got good enough to go to tournaments at my local stores and larger events. I learned a ton about mathematical concepts that hadn't been touched in school (deterministic systems, expected value, hypergeometric calculations, game theory, probability distributions) and logical systems. When I started studying computer programming, a lot of the mental models I'd built in my mind were reused almost word for word with programming concepts such as for-loops, while-loops, if-then-else statements, event handling, event-driven coding vs object-oriented coding, and all the algorithmic ways they could be combined.
It genuinely made me much more intelligent and let me meet a lot of people, and the fun of preparing for and enduring big events improved my mental stamina a lot: 8 hour-long rounds of Swiss in an open format with 20 different decks to consider is a hell of an experience.
It's a shame the game has deteriorated into a crossover cash grab slushpile.
