Just won a game against "BrownHound".
His deck had one card, but he discovered an Ignis weapon that made him draw three cards with each strike. He was playing the Astral Array Priest Standard Priest deck. He burned himself with fatigue.
Unlike the "AdjectiveNoun" bots from 2023, the new bots don't act immediately or mechanistically. They mouse over the cards in their hands before playing. I've also seen one concede when it was obviously going to lose. This AI even destroyed its own Ra-Den.
So, the AI is getting better quickly.
Edit: and my next opponent was "NavyBear", who also played Astral Array.
