A unique Skill that plays every Knife accumulated in the exhaust pile. Knives are cost-0 Attacks, so simply playing them deals damage. The core tactic: use Knife-generating cards like Blade Dance, Trump Card, or Infinite Blades to pile Knives into exhaust, then unleash them all with Knife Trap. With 10 Knives exhausted, you get 10 Attack hits for 1 Energy (upgraded). With Accuracy active, each Knife gains +4 damage, so 10 Knives = +40 damage. Upgraded cost 1 leaves Energy for other cards — major utility boost.

• Requires Knives in the exhaust pile. Pile them up with Blade Dance, Trump Card, or Infinite Blades first.
• Blade Dance is Exhaust, putting Knives straight into exhaust. Combined with Knife Trap, you fire all Blade Dance's Knives later.
• With Accuracy active, every Knife played from exhaust gains +4 damage, hugely boosting total damage.
• Trump Card (cost drops each use) lets you cheaply generate Knives → use → exhaust → Knife Trap loop.
• Upgraded cost 1 allows pairing with a 2-cost card on a 3-Energy turn.

• Blade Dance: Exhaust Skill generating 3-4 Knives. Core combo: Blade Dance pipes Knives into exhaust, Knife Trap fires them.
• Accuracy: +4 damage per Knife Power. Mass-playing Knives from exhaust via Knife Trap multiplies damage dramatically.
• Trump Card: Cost-reducing Knife generator. 0-cost Trump Card floods Knives → exhaust → Knife Trap re-fires them.
• Infinite Blades: Power generating 1 Knife each turn. Accumulate exhausted Knives for a massive Knife Trap volley.
