## Description

MetalSeadramon (EX10-012) is a Level 6 Mega Digimon card from the 2025 EXTRA BOOSTER SINISTER ORDER expansion for the Digimon Card Game. Illustrated by Gamazo, this R-rarity card belongs to the Blue Data attribute and carries the Cyborg and Dark Masters types. It serves as a strategic piece for collectors building archetypes around the Dark Masters lineage.

The card features a distinctive gameplay profile centered on conditional cost reduction and board control. Players can deploy MetalSeadramon with a reduced play cost of 6 instead of 11, provided they have no other Digimon on the field that lack the [Dark Masters] identifier. This effect requires a tactical trade-off, as the Digimon is deleted at the end of the turn it was played. On play and when attacking, it prevents one opponent Digimon and one Tamer from suspending until their next turn, offering significant defensive utility.

For long-term collection, MetalSeadramon includes a strict digivolution constraint, allowing it to digivolve only into Apocalymon. This pathway adds narrative depth for fans of the Dark Masters storyline. Additionally, its on-deletion effect allows the card to be placed face-up as the bottom security card if the player has no blue face-up security cards, providing a safety net for Blue-aligned decks. In the Security zone, it offers a powerful replay value, enabling the free play of a Level 5 or lower Dark Masters card from the hand or trash.

This product represents a key identity piece for the EXTRA BOOSTER SINISTER ORDER set. Collectors and players alike value MetalSeadramon for its complex rules text and thematic consistency within the Dark Masters faction. Whether used for competitive play or set completion, this card exemplifies the intricate design of modern Digimon TCG releases.
