Quick Answers
Most boss losses come from missing one deck job: scaling, burst defense, potion coverage, or draw consistency. Boss preparation starts several nodes before the fight.
Start with Aeonglass and Skulking Colony because they expose slow setup, poor hand quality, and decks that cannot answer several problems in one turn.
