• Effect: Shivs Retain. The first Shiv you play each turn deals 12 additional damage.

A unique Power that gives every Shiv Retain and tacks +9–12 damage onto the first Shiv played each turn. Retain keeps Shivs in hand across turns, so unused Shivs accumulate indefinitely. The first-Shiv bonus fires guaranteed every turn, turning a 0-cost Shiv into a 12–15 (15–18 upgraded) damage spike. Stack Accuracy on top and the first Shiv explodes into even higher damage. Because Shivs stockpile in hand, dumping them right before a Finisher play is a natural kill-turn pattern. In long fights, the retained Shiv pile builds an overwhelming advantage.

• After playing Phantom Blade, hold Shivs in hand. Play only the first Shiv each turn for the bonus and let the rest accumulate.
• On the kill turn, dump every stockpiled Shiv, then close with Finisher for enormous damage.
• With Accuracy, the first Shiv gets both Accuracy's +4–6 and Phantom Blade's +9–12 for a high-damage opener.
• Infinite Blades feeds Shivs every turn; Phantom Blade keeps them in hand. The hand fills with Shivs rapidly.
• Upgrade bumps the bonus to 12 — the first Shiv each turn becomes 3 (base) + 12 = 15 damage minimum.

• Accuracy: +4–6 Shiv damage (Power). Combined with Phantom Blade's +9–12, the first Shiv hits for 13–18+ damage.
• Infinite Blades: generates a Shiv at turn start. Every generated Shiv Retains, flooding the hand fast.
• Finisher: damage per Attack played. Burn the stockpiled Shivs first, then close with Finisher for a monster swing.
• Tactician: retain at end of turn. Phantom Blade already retains Shivs, so Tactician layers on extra retention for stable hand shaping.
