Difficulty setting in the save game (or possibly "current game") determines the thinking time avaliable to the AI, regardless of what is set in the .ini. This probably doesn't mean that the value is somehow overriden after initialisation, but one can hope.

Would it be possible to hook up a separate enemies.ini or script or something which would override the "will attack" , "will block" and other such values temporarily but for individual enemies? Because the big problem with the AI is that it's trying to use an universal/global model for enemies with different lives in different colors and with different decks which is just never going to work. A deck which starts at 4 life and a deck which starts at 24 are playing a different game, etc.

I suppose this depends on whether these numbers can be changed without restarting the game, but I do have to ask
