Can you port the openETG AI to this?
A problem I see is that oetg-vanilla only has the game rules. It is doable though (involves a good amount of work), as the oetg AI no longer uses specific checks for situations or cards, but rather uses whatever the rules are (iirc).
It would take longer to simulate, as the AI is much heavier, but the results would be more accurate, as the AI is fairly competent.
