Winning in Magic takes a lot: creativity, problem solving, and psychology, all of which also help winning in life. A relatively new summer program called SPARC (http://sparc-camp.org/) targets quantitatively talented high schoolers to improving decision-making, both for humans and for computers (e.g. Bayesian statistics, machine learning, game-playing, and *practical* cognitive science). The program has been around 2 years, and has a highly competitive selection process that may be a good fit for Magic players with some quantitative background. SPARC seeks to take goal-oriented, mathematically talented problem solvers (possibly like you!) to approach life in general with a winning mindset -- it may even improve your Magic game.
The application is at http://sparc-camp.org/apply/ and the second-round interviews start April 15th (completing the first-round applications early gives more time and information for the part 2 of the process).
