hehehe, apparently I messed something up. So I gave the players some cards in their decks, moved 10 of them in their hand, and I was waiting anxiously for the AI to show me how smart it is, and the AI went through the motions of the finite states, got to the point where it evaluated and chose a tactic as ‘MINIMAL WIN’ as expected because it’s the first hand in the game, and then proudly spit out the creature card with the maximum value in its hand ( a 10) instead of the expected creature card with a minimum value (a 1). but… But… What just happened? 
Anyways, I think I have to shift the polarity of my sorting, hopefully this would turn the AI from Forrest Gump into an Einstein hehehe
