MTG turing machine, lol Show more
Never have I had to reference the halting problem and Scryfall (former magiccards.info) to understand a preprint.
From the discussion: the set up with a legacy legal deck
"Once everything is set up, Steely Resolve is cast, and then Karn Liberated and Capsize are used to exile all setup permanents and all cards from Bob’s hand, eventually exiling Capsize and Karn Liberated themselves. Now no player has any remaining choices except to let the Turing machine execute."
