## Description

Chaosmon: Valdur Arm (BT4-091) is a significant Level 7 Mega Digimon card from the 2020 Great Legend set in the Digimon Card Game. As a Vaccine-type entity with a substantial Play Cost of 15 and 14,000 DP, this card represents a powerful late-game presence for collectors building competitive decks or expanding their roster of high-level creatures. The card's design and mechanics focus on overwhelming board control, making it a key piece for enthusiasts of the franchise's tactical depth. The strategic value of this card lies in its dual-action ability. Upon digivolving, Chaosmon: Valdur Arm triggers its effect twice, allowing the player to reduce one of the opponent's Digimon DP by 7,000 for the turn. This massive reduction can effectively neutralize opposing threats or facilitate easier elimination. Furthermore, the card offers a secondary benefit upon deletion, granting the player 3 memory. This memory gain can be crucial for accelerating plays or recovering resources during intense matches. Whether you are completing set challenges, investing in high-level Digimon, or seeking cards with unique mechanical interactions, this card offers distinct collector appeal. Its SR rarity within the set makes it a sought-after addition for those who appreciate the strategic complexity of the Digimon Card Game universe. The card's attributes—White color, Vaccine attribute, and Mega form—place it firmly within the established lore and mechanics of the series. Collectors interested in the evolution lines of Chaosmon or those who value cards with high DP thresholds will find this release noteworthy. The combination of offensive pressure through DP reduction and resource recovery through memory gain defines its role in gameplay. This catalog entry serves as a reference for the card's identity and mechanical profile within the broader context of the Digimon TCG.
