You can only activate this card when a Continuous Trap Card is activated. Negate all Continuous Trap Cards during the turn this card is activated.
Metal Detector — Power Evaluation
Final Score: 37 ± 8 · Confidence: Low
- Intrinsic: 41 · Deck: — · Meta: provisional
- Primary role: Removal / Negation
Why it scores here
Metal Detector is a specialized tech card that negates all Continuous Trap Cards for a single turn, but only when you respond to one being activated. While it offers strong, broad negation of a specific card type, its extreme narrowness (zero value outside Continuous-Trap-heavy metas), reactive activation requirement, one-turn duration, and high garnet risk in most formats severely limit its general power. The card has no combo generation, no resource advantage, and no material utility—it is purely a defensive meta-call.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Requires opponent to activate a Continuous Trap to function, making it reactive and meta-dependent; set-and-wait is worse than proactive search routes (inferred). |
| Combo & Conversion | 3 | Zero combo extension or material generation; a Trap Card with no summon effects or board-building (verified). |
| Resource Economy | 47 | Soft removal of an opponent's Continuous Trap for one turn, roughly even in the best case and a brick in the worst, with no card draw or advantage engine (inferred). |
| Effect & Interaction | 58 | Negates all active Continuous Trap Cards during one turn, offering broad negation against a specific card type, but only for one turn and only when triggered (verified). |
| Material Utility | 3 | Trap Card with 0 ATK/DEF and no monster type; cannot serve as material for any summon or effect requiring a monster (verified). |
| Resilience & Flexibility | 32 | Set Trap vulnerable to destruction before activation; one-turn negation duration provides no ongoing resilience; narrow utility limits flexibility to Continuous-Trap metas (inferred). |
| Deck-Building Efficiency | 38 | Meta-dependent tech card with high garnet risk if Continuous Traps are uncommon; 1–2 copies maximum and only in side deck in relevant metas (inferred). |
Calculation
Weight profile: Removal / Negation. Intrinsic ≈ 41, Deck ≈ —, Meta = provisional. Modifiers: Garnet risk (meta-dependent) (-4). Final formula: Intrinsic only (no decks/combos available)
Strengths
- Broad negation of all Continuous Trap Cards in a single turn (not just one target)
- Free activation with no hand cost (normal Trap slot cost only)
- Reactive timing allows setup and baiting
Weaknesses
- Purely reactive; requires opponent to activate a Continuous Trap
- One-turn duration; Continuous Traps are live again on opponent's next turn
- Zero value if opponent deck contains no Continuous Traps (high garnet risk)
- Trap Card on-field is vulnerable to MST, Twin Twisters, Cosmic Cyclone before activation
- Cannot generate advantage, material, or board presence
Counters / choke points
- Decks with no Continuous Trap Cards (negates this card's value entirely)
- Spell Speed 2+ Trap removal (MST, Twin Twisters, Cosmic Cyclone) activated before Metal Detector
- Floating effects that replace destroyed Continuous Traps
Best use
Side-deck tech against opponent's Continuous Traps. Decks: Continuous-Trap-heavy Stun decks, Floodgate-reliant control decks (if they themselves avoid Continuous Traps).
Evidence & gaps
- Verified: Card text: activates when a Continuous Trap is activated; negates all Continuous Traps during that turn (card description); Trap Card type with 0 ATK/DEF; no monster frames or summon effects (card properties)
- Inferred: Activation is reactive and opponent-dependent; not proactive like Hand Traps or search-based starters; Negation duration is one turn only; does not provide ongoing protection; Tech card for Continuous-Trap-heavy metas; zero value outside that context; Soft removal-only; no resource advantage generation or draw; High brick risk in metas without prevalent Continuous Traps
- Data gaps: No decks supplied—cannot measure deck synergy, inclusion rates, or practical accessibility No combos supplied—cannot determine actual combo extension or activation patterns No usage statistics (StatisticsCard)—archetype-specific inclusion rates unknown No guides supplied—no expert commentary on meta-specific applicability No banlist token—assumed unlimited (3 copies) in all formats Meta snapshot unavailable—Continuous Trap card prevalence unknown, making power assessment highly provisional
