hehe seriusly cant wait to get my first planeswalkers, just gotta wait until may 2nd!!!!!

Should I go to my LGS's prerelease?

I would say yes. Prerelease tournaments are often intended to be beginner-friendly, and it's a good way to play with new cards.

Someone has constructed a Magic: the Gathering Turing Machine with only mandatory actions

Previous Turing machines constructed in Magic required multiple players to make specific choices for it to work

This one just requires one player to make specific choices during setup, and then it runs on its own

ok cool thanks

I am confused what is a turing machine?

A Turing machine is a mathematical abstraction that represents a computer

It is commonly believed that a Turing machine can compute anything that is intuitively "computable", or in other words that a Turing machine is at least as "computationally powerful" as any other computer

So, if you can make a Turing machine using the game of Magic, certain results in math and computer science can now be applied to Magic itself

The most practical implication of this is that some game states are impossible to shortcut because you can't know how it will end without playing it out, and that playing it out can take effectively an arbitrarily long time
