As a C-rarity card, it serves as a staple in many decks, offering accessible gameplay value without the scarcity of higher-tier parallels. The card identifies Yu as a member of the Shuchiin subtype, aligning him with specific faction strategies within the game's complex ecosystem. For players building their Weiß Schwarz collections, this card is notable for its dual-auto mechanic that encourages aggressive deck manipulation. The first effect triggers when Yu is placed on the stage from the hand, allowing the player to reveal the top card of their deck. If that card is a 《Shuchiin》 character or an event, it can be added to the hand, followed by discarding another card to the waiting room. This creates a powerful resource engine that fuels further plays. The second effect provides defensive utility; if Yu becomes 【REVERSE】 in battle, the controller may move an opponent's card from their clock to the waiting room, forcing the opponent to put a card from their deck into their own clock. This interaction makes Yu a versatile piece for controlling the pace of the game. Collectors of anime-themed TCGs often seek out cards from the Kaguya-sama: Love is War set due to its faithful adaptation of the source material's strategic depth. The Weiß Schwarz brand is known for its intricate rules and deep strategic layers, and cards like KGL/S79-E013 exemplify this design philosophy. Whether you are completing a Shuchiin-themed deck or expanding your library of anime TCG cards, this release offers a compelling addition for both competitive play and casual collection. Understanding the nuances of Yu's abilities helps collectors appreciate the tactical choices available within the Kaguya-sama: Love is War set. ## FAQ ### What does the Happiness Tax, Yu card do in Weiß Schwarz?
