Adrenaline

Adrenaline is a 0-cost rare Skill card for the Silent that gains 1 energy, draws 2 cards, and Exhausts. At zero cost with energy gain, it effectively pays for itself while providing card draw, making it a pure value card. The Exhaust means it only fires once per fight, but the impact is immediate.

Adrenaline enables expensive plays like Wraith Form and Bullet Time by providing bonus energy. The 2 cards drawn help find combo pieces alongside Backflip and Acrobatics. Nightmare can copy Adrenaline for 3 free energy and 6 card draws next turn. Well-Laid Plans can Retain Adrenaline for the turn when you need the energy and cards most.

Silent players should pick Adrenaline in virtually any deck, as free energy and card draw is universally valuable. It is exceptional in combo-heavy decks that need to align specific cards on a single turn. The card shines against bosses like Kaiser Crab and Doormaker where the extra energy and cards can mean the difference between survival and defeat.
