(Edit: Un'goro Lost City expansion patch on July 2025 have also changed the AI, and this Chess boss now works properly and is beatable)
I was planning to do Heroic Karazhan runs, but recent AI update made Chess very hard to beat. I only won 1 out of 10 attempts. So I'll probably postpone the Heroic Karazhan runs until a future AI update.
My decklists are available here, if you guys want to see what's the latest strats are for Heroic Karazhan bosses.

Turn-6 kill in Scarvash, never had it this quick before. Happened on one of my recent resetless runs.

Turn 2 kill with infinite Antonidas Fireballs. Happened during a full-run attempt, was hesitating a bit at the start cause I wasnt sure if I do got the combo already.

(Edit: Turns out this trick doesnt work on Nazra + Malchezaar too, probably something to do with the recent change in interaction rules.)
Turns out you have to resummon the Horsemen for the trick to work, which isnt necessary for the Free Medivh fight. Can anyone explain this?
Maybe in the Free Medivh fight, it works because the game ends your turn immediately after Nazra is killed.
Anyway, I still win this game two turns later because my Beardo is still alive. I was testing Uther DK to be used on Heroic Rafaam Unleashed, which will be significantly faster than my old Druid deck if it can be consistent.")
