This card serves as a versatile tool within the game, providing essential utility that can shift the momentum of a match. As an Event card with a low cost of 1, "Weakness...Is an Unforgivable Sin." is designed to be played frequently and flexibly. Its primary function revolves around resource management and power boosts. By utilizing the DON!! Mechanic, players can return cards from their field to their DON!! Deck to activate a counter effect. This allows them to select one of their Leader or Character cards and grant it a +1000 power boost for the remainder of that turn. This sudden increase in power can be the deciding factor in overcoming an opponent's defense or securing a crucial battle. Furthermore, the card offers a trigger effect that aids in deck stability. When triggered, it allows the player to add up to one DON!! Card from their DON!! Deck directly to their active field. This ability helps maintain a steady flow of resources, ensuring that players have the necessary energy to continue their attacks or defend their position. For collectors and players alike, integrating this card into their One Piece Card Game collection adds a layer of strategic nuance, particularly for those building decks centered around the Baroque Works faction or The Seven Warlords of the Sea theme.
