Crystal Doll
Skill Explanation:Enhances 1 selected card to Crystal Card.
Crystal Card:×2 Mult 1/4 chance to destroy card.

Comprehensive Evaluation:
(1) Cost-Effectiveness: ★★★
The core advantage of this card lies in its powerful ×2 Multiplier bonus. In the early-to-mid game when the deck’s base multiplier is still low, a single Crystal Card can drastically boost scoring efficiency, providing significant help for clearing low-difficulty stages quickly. However, the 1/4 self-destruct chance carries a notable risk—especially if you convert a core deck card, it may cause a critical bonus gap in key rounds. Additionally, it can only convert one card at a time, limiting its bonus coverage in late-game multi-core high-multiplier deck setups.
Recommendation: Ideal for early-to-mid game single-core rush decks. Prioritize converting high-value base cards to maximize benefits. For late-game decks with more stable multiplier-boosting options, it is advisable to replace this card with risk-free synergistic enhancement cards.
(2)Operation Difficulty: ★★
Moderately easy to master. The basic operation only requires selecting one target card for conversion, but the core challenge lies in timing the play of the Crystal Card. You need to judge when to play the card based on the match progress—maximizing the ×2 Multiplier bonus while avoiding self-destruction that could disrupt deck rhythm. Additionally, avoid converting core functional cards into Crystal Cards to prevent the deck from collapsing after self-destruction.
