It’s possible to build a Turing machine within Magic: The Gathering
It may be a highly unlikely scenario, but a recent paper posted on the physics arXiv proves that it’s possible in principle to build a simple computer within this massively popular tabletop game using just the right combination of Magic cards. While the inputs must be pre-programmed, “Literally any function that can be computed by any computer can be computed within a game of Magic,” said co-author Alex Churchill, a longtime Magic fan who has been working on the problem for several years.
