## Description

Fei is a Tamer card from the 2025 BOOSTER HACKERS' SLUMBER expansion, identified by the set code BT23-083. This card belongs to the Zaxon and CS types and utilizes a dual-color identity of Green and Black with a play cost of 4. Illustrated by Nakano Haito, the card is a Rare (R) rarity within the set, appealing to collectors of the Digimon Card Game who appreciate strategic depth and specific archetype integration. As a Tamer, Fei serves a pivotal role in deck construction by focusing on resource acceleration and hand management rather than direct defense or attack power. The card’s abilities are centered around gaining memory, the game’s primary resource for playing cards. During the start of the Main Phase, Fei provides a passive benefit: if the player controls a Digimon with the [Royal Base] or [CS] trait, they gain 1 memory. This effect encourages the inclusion of specific Digimon in the deck to maximize consistency. Additionally, Fei has an active effect tied to security checks. When cards are revealed from the security stack, if any possess the [Zaxon] or [Royal Base] trait, the player may suspend Fei to gain 1 memory. This interaction rewards decks that utilize security layers featuring these specific traits, creating a synergistic loop that benefits both resource accumulation and defensive play. A unique feature of Fei is her security effect. If the card is placed in the security stack, it can be played without paying its cost when revealed, provided the player has 7 or fewer cards in their hand. This clause offers a crucial safety net, allowing players to recover a key Tamer from defense when hand size is low. This mechanic makes the card a valuable inclusion for players seeking to stabilize their position during critical moments of the game. Collectors value this card not just for its gameplay utility but for its contribution to the evolving meta of the BOOSTER HACKERS' SLUMBER era.
