## Description

ST21-04 Zudomon, a Level 5 Ultimate Digimon from the HERO OF HOPE [ST-21] release, stands as a formidable presence in the Digimon Card Game. This Blue Vaccine card brings a unique combination of offensive disruption and team synergy, making it a versatile choice for competitive play and collection building. As a Universal rarity card, it is accessible to players while maintaining significant strategic value.

Zudomon’s kit revolves around controlling the opponent’s board state. Upon playing or digivolving, it can trash a digivolution card from an opponent's Digimon based on the number of colors in your Tamer lineup. This effect scales effectively, allowing for efficient resource denial against multi-colored decks. Additionally, it can return a weaker opponent Digimon—specifically those with one or fewer digivolution cards—directly to their hand, further disrupting their strategy. These removal effects make ST21-04 a key piece for players looking to neutralize threats and manage the battlefield.

Beyond its removal capabilities, Zudomon offers substantial value for players utilizing the [ADVENTURE] trait. During your turn, whenever other Digimon are played or digivolve and possess this trait, Zudomon grants ＜Alliance＞ to one of your Digimon for the turn. This keyword allows a Digimon to attack twice, significantly increasing your damage output and enabling powerful combos. The card’s design emphasizes its role as a central engine for synergy-based strategies, rewarding players who build cohesive teams around specific traits.

For collectors, ST21-04 represents a staple of the HERO OF HOPE set. Its clear text box and powerful effects make it a recognizable and sought-after card among enthusiasts of the TCG. Whether you are building a competitive deck focused on board control or simply expanding your roster of Blue Vaccine Digimon, Zudomon offers both mechanical depth and collectible appeal. The card’s balanced stats and versatile effects ensure it remains a relevant and valuable addition to any Digimon Card Game collection.
