## Description

The Greymon card, designated as BT21-057 in the 2025 Digimon Card Game WORLD CONVERGENCE [BT-21] set, bridges the digital world with a modern pop culture crossover. This Black Vaccine Champion Digimon brings a Level 4 presence to the battlefield with a Play Cost of 4 and 4000 DP.

This disruption mechanic provides tactical flexibility, enabling players to control the board state or force unfavorable trades. Additionally, the card includes an Inherited effect for the Reboot keyword, adding another layer of strategic depth for those who utilize inherited effects in their gameplay. The U rarity designation marks this card as a common find within the set, making it accessible for both casual players and serious collectors looking to expand their roster. The WORLD CONVERGENCE [BT-21] set appeals to fans of both the Digimon franchise and the BT-21 characters, creating a unique niche in the trading card game market. Whether you are a long-time Digimon fan or new to the TCG scene, this Greymon card represents an interesting intersection of classic gameplay mechanics and contemporary character design.
