Ability: Reduces your available Plays to 1. This is one of the most challenging boss abilities, as you only get one attempt to hit the score requirement. Consistency is paramount.
Strategy: Your deck must be highly optimized to consistently draw a strong hand. Prioritize deck thinning (using 'The Hanged Man' Tarot) and card duplication ('The Fool') to increase the probability of drawing your key cards. Ensure you have Jokers that provide massive chip and multiplier bonuses, as you won't have many chances to accumulate score. If you have a strong hand in your opening draw, play it. Otherwise, use your single discard wisely to fish for a winning hand. Consider Jokers that provide a bonus for the first hand played.
