It would be interesting if it could make balanced cards. I wonder what kind of crazy op decks these generated cards allows for

Humans aren't exactly great at this either; cards needing to be banned has only gotten more frequent over time, although it looks like this year has been the first one in a while not to require a lot[1]

  • I'd argue that humans are actually pretty fucking good at this. After all, it's humans who are exploiting the weaknesses WOTC build into the game via new card releases. Balance testing is a numbers game though. If you test your software you can be reasonably confident if you release it to 10 people, it'll perform pretty much as expected. If that software is installed by millions of people, you're going to start experiencing every edge case that can only occur in extremely rare circumstances.

    Or another example, the software released to ten customers can be insecure with little repercussions. But insecure software released to millions is going to be zero-day'd in no time. The MTG community absolutely has hackers that are just waiting for the latest vulnerability to be released.

    The latest set released by WOTC this week has an infinite mana loop that you can get on turn four. I don't think this stuff will ever stop, and I honestly hope it doesn't. Bans / restrictions can mitigate the damage to certain formats, and it really stirs up the creativity of folks in the meantime.

    • This seems like a question of linguistic semantics, but I'd argue that groups of humans are only good at this at the scale where its not so much a skill of the individual humans but a property of the larger system itself. Millions of humans individually trying to figure out how to exploit some new cards aren't going to be anywhere close to as good as millions of people playing games against each other to try things out, and at that point, it's not obvious to me that humans even scale as well compared to what might be possible with a computer program.

  • There has been a paper on using genetic algorithms for deckbuilding in magic[0]

    I'm working on at least partially reproducing and improving upon the paper but the reality is that MTG as a game is really hard to implement (and a shitload of work) so i'm building my own MTG inspired game to try and balance it using genetic deck building.

    • Interesting! Is there a way I can keep up with this?

      edit: I mistakenly thought you authored the paper, but if you do make progress on your game definitely update us

  • You’d expect that to happen as potential interactions increase, I assume. I’ve always wanted to learn how to use a modelling tool like TLA+ or something to find breaking issues in games - like first turn wins (that isn’t just Exodia in Yugioh)

    • Many of the recent bannings haven’t been accidental combos though, they’ve just been power creep. Wizards is in a tough spot these days because Commander players and people playing cube want a constant stream of new cards that have to be usable in an eternal format.

      One good result of this power creep, if anything, has been that Wizards is increasingly willing to _unban_ cards which are no longer overpowered.

    • Read up on the Power Nine sometime. They mostly look innocent but would lead to first turn win decks.
