Why it scores here
Terrors in the Hidden City is a continuous support spell whose value is protecting face-down Defense Position monsters from opponent card-effect targeting and giving flipped-up monsters +1500 ATK/DEF while it stays face-up. Its recursion clause only triggers if an opponent's effect destroys it, so it is a conditional recovery rather than card advantage. Its strength is observed in Subterror lines (30.5% of sampled decks, with 1.83 copies on average), not in its stats; no combo boards were supplied, so combo conversion is scored from text only and kept low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Carried in 210 sampled decks at 1.83 copies on average, but no as_starter or as_searched data exists to show how often it is drawn live (observed/inferred). |
| Combo & Conversion | 25 | Text only: it adds +1500 to monsters flipped up while it is face-up, which needs a setting or flip engine; there are no combo examples or power_index values (inferred). |
| Resource Economy | 30 | No draw or search; the only return is a GY Special Summon if an opponent's effect destroys it, which is conditional (verified text). |
| Effect & Interaction | 45 | Blocks opponent card-effect targeting of face-down DEF monsters, a soft protection rather than negation or removal (verified text; scale is inferred). |
| Material Utility | 30 | Continuous Spell with no material value and no body it provides (verified frame and type). |
| Resilience & Flexibility | 55 | Persists as a continuous card and its recursion clause rewards being destroyed, but it is a single S/T-zone piece that an opponent's effect can remove (inferred). |
| Deck-Building Efficiency | 70 | Runs at 1 to 3 copies with no garnet or lock and appears across 47 archetypes, though it is concentrated in Subterror (observed). |
Calculation
Weight profile: Utility / no clear role (default) weights; no secondary blend applied because the primary role is the default utility profile. Intrinsic ≈ 46, Deck ≈ 50, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Protects face-down Defense Position monsters from opponent card-effect targeting
- Gives flipped-up monsters +1500 ATK/DEF while it is face-up
- Recursion clause returns a GY monster when an opponent's effect destroys it
- Low-cost slot: 1 to 3 copies, no garnet or lock restriction
Weaknesses
- No combo evidence: as_starter, as_material and payoff shares are all zero
- Benefit is conditional on a setting or flip engine
- Protection only covers face-down DEF monsters, not the whole board
- Opponent effects that destroy or remove the spell end the recursion clause
Counters / choke points
- Opponent card-effect removal or destruction of the spell itself
- Opponent effects that ignore the targeting restriction, such as non-targeting effects

Evidence & gaps
- Verified: Card text: opponent cannot target face-down DEF monsters you control with card effects; Card text: flipped-up monsters gain 1500 ATK/DEF while it is face-up; Card text: GY Special Summon of a monster in face-down DEF if it is destroyed by an opponent's card effect; Card type: Continuous Spell; formats TCG, OCG, DuelLinks
- Observed: Present in 210 sampled decks at 1.83 average copies, max 3; Subterror archetype in 30.5% of sampled decks; 47 distinct archetypes overall; Top partners are Subterror cards at roughly 25 to 45% co-occurrence; No combo boards supplied (total_combos 0)
- Inferred: Its flip-buff and protection work mainly with a set or flip engine; Its deck role is supporting rather than standalone power; Recursion is conditional and rarely triggered in practice
- 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 the deck sample only no starter-count data, so DeckResilience is scored neutral
