Strike
Strike (Silent) is the green version of the universal starter attack: 1 Energy, 6 damage (9 upgraded). Like all Strike variants, it forms the backbone of the starting deck but is typically replaced as quickly as possible. The Silent has better early attack options available than other characters — cards like Dagger Spray, Bane, and Poisoned Stab all offer more utility per Energy.
The Strike name does not interact with the Ironclad's Perfected Strike, so for the Silent it truly is just a vanilla attack. Thinning the deck of Strike copies frees you to cycle through your more powerful poison, shiv, and discard synergy cards more reliably. Replace these as soon as you can.
