Frank Karsten has been playing competitive Magic for over half his life, and he was inducted into the Pro Tour Hall of Fame in 2009. Synergy-driven aggro decks like Modern Affinity are his favorite. Frank holds a PhD in cooperative game theory and stochastic operations research, so when he's not traveling the world, he enjoys applying his mathematical background to Magic-related problems.
