Silent rewards planning. She often looks weak for one turn, then wins because poison, draw, and defense line up at the right time.
Do not ignore front-loaded damage
Poison is excellent in long fights, but Act 1 still asks you to kill enemies quickly. Add immediate damage before taking too many slow cards.
Draw turns good cards into consistency
Silent can support more situational cards once she has enough draw and discard. Without draw, those same cards clog the hand.
Block plans need scaling too
Dexterity, weak, discard defense, or repeatable block engines help Silent survive while poison finishes the fight.
