## Description

The Mastemon SR Digimon Card (BT3-090) from the 2020 Release Special Booster Ver.1.5 set stands as a formidable entry in the Digimon Card Game. As a Level 6 Mega Angel-type Digimon with Vaccine attribute, this card represents the pinnacle of strategic power within the Purple color identity. Collectors and players alike value this Super Rare card for its significant DP of 12000 and its high memory cost of 12, which reflects its substantial impact on the board state. Within the context of the Release Special Booster Ver.1.5, this card serves as a key component for players building robust decks around late-game power plays. The card’s unique effect triggers during digivolution, allowing the player to trash one card from the top of both security stacks. This disruptive capability is followed by the ability to play a Level 4 or lower Purple or Yellow Digimon from the trash without paying its memory cost, providing crucial resource recovery and board presence. This mechanic makes Mastemon particularly appealing for collectors who appreciate cards that offer both defensive security disruption and offensive flexibility. Whether you are focused on completing your set collection or seeking powerful cards to enhance your competitive strategy, understanding the specific attributes of each card is essential. The BT3-090 designation ensures easy identification for cataloging purposes, while the SR rarity marks it as a sought-after item for those who appreciate the depth and complexity of the Digimon universe. By focusing on the card’s mechanical design and strategic role, collectors can make informed decisions about their acquisitions, ensuring that every addition to their collection serves a purpose in their gameplay journey.
