Hugo Thomel's team introduces ANA (A Normal Adversary), an action model for Magic: The Gathering that mimics human play. With only 5M parameters, it runs on CPU, making decisions in 12ms and predicting human picks with 90% accuracy. The team sees this as a step towards people-shaped policies, with future applications in robotics. Try it now.
