The deck leverages Jace's passive to protect him from attacks by taxing opponents, buying time to repeatedly use his +1 for card selection and hand sculpting while ticking up his loyalty. The -3 ability is the engine's payoff, exiling a creature or planeswalker you control to cheat a more powerful creature or planeswalker directly from the library onto the battlefield, rewarding a deck packed with high-impact permanents. The strategy revolves around protecting Jace long enough to chain multiple -3 activations, cycling through the library to deploy an overwhelming succession of threats.
