• Cost: 0
• Effect: Add a copy of an Attack card from your hand to your hand.

An amplifier card that copies a strong Attack so it can be used twice. Copying a high-cost, high-damage Attack doubles burst damage in a single turn. Once Upgraded it becomes 0 cost, which makes it even easier to fit in.

The basic play is to target the strongest Attack in the deck and copy it. In boss fights, copying a high-damage Attack is an effective way to put up a huge damage turn. Upgraded, the 0-cost further improves Energy efficiency.

• High-cost, high-damage Attacks: Copying a heavy hitter doubles its output, raising the ceiling of a single turn.
• Strength buff cards: Strength applies to the copied Attack too, so the more hits there are, the larger the payoff.
• Energy generation: Helps secure the Energy needed to actually play both copies.
