As someone who does not play Magic The Gathering, how exactly is having a board state which depends on a prime conjecture advantageous? And if it is, how does one extend this to Monopoly?
MtG is a deck-building game, rather than a board game. They keep issuing new kinds of cards, with new capabilities. You can make your deck out of any cards you like (depending on who is running the game).
The number of possible interactions is vast, and people delight in discovering clever combinations. Sometimes those combinations can even break the game (like, winning before your opponent even begins). They're so powerful that they're made illegal.
A key element of the game is that you will draw your cards in random order, so even if you have a super-powered combination, you need to draw it before your opponent draws their own.
This particular combination of moves requires a lot of very specific cards. Even if you put all of then in your deck, it will take you a very long time to get them out. Meantime, your opponent is likely to kill you in a more conventional way.
This isn't realistic. It's more akin to a chess problem, a thought exercise in what you could do.
Similarly, you can arrange your deck to form a Turing-complete computer:
I am not sure that arranging a deck to form a turing complete computer is an impressive feature. It would be much more impressive if you couldn't ubder any circumstance :)
