Legendary Wind-Up Key — Power Evaluation
Final Score: 30 ± 6 · Confidence: Medium
- Intrinsic: 30 · Deck: 30 · Meta: provisional
- Primary role: Utility · Secondary: Floodgate/Control
Why it scores here
The card's text only flips the controller's own face-up Wind-Up monsters to face-down Defense Position. It converts nothing into board, cards, or interaction against the opponent, so the score stays low. Its presence in all 4 sampled decks, always alongside Wind-Up partners at 100%, shows it is a practical niche tool, not a high-power card. The Wind-Up archetype identity and a single-copy slot cost limit the generic portability and deck score, and the lack of combo evidence keeps confidence at Medium.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | It is a Quick-Play Spell played in 4 of 4 sampled Wind-Up-adjacent decks at 1 copy each, but no searcher or hand-route evidence exists (observed deck inclusion; no combo stats). |
| Combo & Conversion | 15 | Its text does nothing without face-up Wind-Up monsters to flip, and combo data is empty, so no starter or payoff role is observed (verified text; inferred conversion). |
| Resource Economy | 10 | It is a card-for-nothing play with no draw, search, or recursion in its text, so it costs a card for a repositioning effect (verified text). |
| Effect & Interaction | 5 | It affects only the controller's own monsters and has no opponent-facing negation, removal, or floodgate clause (verified text). |
| Material Utility | 10 | Its body is a Spell and never becomes material. It also does not change the material value of Wind-Up monsters beyond their position (verified text). |
| Resilience & Flexibility | 25 | No evidence exists on how it survives a negate or how it can be used across turns; as a Quick-Play it has some timing flexibility, which is inference from the card type alone. |
| Deck-Building Efficiency | 60 | It is run as a single copy in each sampled deck, so it takes one slot with no garnet or lock restriction, though it is useful only in a Wind-Up shell (observed deck copies; verified text). |
Calculation
Weight profile: Utility / no clear role default (no secondary blend applied; Floodgate secondary noted but not weighted). Intrinsic ≈ 30, Deck ≈ 30, Meta = provisional. Modifiers: Archetype-restricted utility (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap single-copy Spell that fits a Wind-Up shell without a garnet or lock cost
- Consistently included alongside Wind-Up partners in sampled decks (observed)
Weaknesses
- Does nothing on its own; requires face-up Wind-Up monsters to have any effect
- No card advantage, search, or opponent interaction in its text
- No combo evidence, so its real board conversion is unverified
Counters / choke points
- Any effect that stops it from resolving or negating it in response (generic spell negation; inferred)
Best use
Utility repositioning tool for a Wind-Up board. Decks: Wind-Up. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: flips all face-up Wind-Up monsters you control to face-down Defense Position; Quick-Play Spell, Wind-Up archetype, legal in TCG, OCG, MasterDuel, DuelLinks
- Observed: Included in 4 of 4 sampled decks at 1 copy each; Top partners are Wind-Up monsters at 100% co-occurrence
- Inferred: Utility role: no opponent interaction or card advantage in text; Dead outside Wind-Up boards, so archetype-restricted modifier applied
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
