I think the AI has gotten a little smarter with the new update (?)
However, it is still doing things that make absolutely no sense. For example:
Stealing/destroying an hourglass when getting rid of my shield would have won the game.
Playing a SoP when it has enough damage out to kill in one turn.
Using the dive ability when my shield will block the creature.
Playing fractal before playing all other cards it can play.
Fractalling and playing Ball Lightning when my shield will block it.
