Kyle Hill of Because Science explains and demonstrates, using real cards, how Magic: The Gathering can be used to build a Turing machine, a computer inside the card game.

HN links it as the accessible, hands-on demo behind the claim that Magic is Turing complete.

Here's a demo: ▶ this video Didn't realize this before watching, but it's interesting that there's an incredibly complicated board state but the game state / actions are deterministic, e.g. the players don't have any choices about what to do once the machine is set up.
