So, what I used now is kind of a mix of aggro and exploits to try to maximise consistency. Druid, Paladin and Warrior is quite consistent now, and Rogue, Shaman and Hunter is quite easy if you get the right mulligan.
Warlock, Priest, and Mage is really inconsistent for me, and looking for faster decks. I do Mage first because you need the Molten Giants in the mulligan, and it's better to just keep resetting until you get it, otherwise it is impossible.
Maybe murlocs are the way to go for Mage and Priest? Warlock is difficult because of the duplicate restriction but I guess you can take 20 damage at the start.
Hey! I'm new to this forum but long time lurker of r/speedrun and I was wondering if there is any interest to launch the category "Lich King All Classes". I feel like the difficulty is hard enough to justify a speedrun of it without it being too RNG-heavy, and there are already some exploits that you can do with some of the classes.
Tell me what you think and I can start making some ideas of decklists!
