## Description

The Gamma Knife card, identified by the catalog number OP05-077, is a distinctive purple Event card from the One Piece Card Game OP-05 set released in 2023. As a member of the Heart Pirates trait, this card offers players a unique strategic tool for managing board control and resource management during gameplay. With a cost of 2 DON!!, the card provides two distinct effects that can shift the momentum of a match.

During the Main phase, players can activate the card to reduce an opponent's Character power by 5000 for that turn. This effect requires returning one DON!! card from the field to the DON!! deck, making it a tactical decision that balances immediate power reduction with resource preservation. This mechanic allows collectors and players to build decks that can effectively neutralize key threats without depleting their entire board state.

Additionally, the Gamma Knife features a Trigger effect that activates upon being played. This effect allows the player to add up to one DON!! card from their DON!! deck directly to their active field. This resource recovery option helps maintain board presence and supports further plays, making the card a versatile addition to any Heart Pirates strategy. The combination of power reduction and resource recovery makes the OP05-077 Gamma Knife a valuable piece for enthusiasts of the One Piece Card Game.

Collectors often seek out cards like the Gamma Knife for their unique gameplay mechanics and their place within the broader OP-05 set narrative. Whether building a competitive deck or expanding a personal collection, this card represents a key interaction point for Heart Pirates strategies. The One Piece Card Game continues to grow in popularity, and cards like OP05-077 are essential for understanding the diverse strategies available to players.

For those looking to complete their OP-05 collection or add a functional Event card to their arsenal, the Gamma Knife offers both strategic depth and collectible value. Its purple color and Heart Pirates trait align it with specific deck archetypes, making it a sought-after component for dedicated players.
