Scarlet Security — Power Evaluation
Final Score: 49 ± 7 · Confidence: Medium
- Intrinsic: 46 · Deck: 51 · Meta: provisional
- Primary role: Board breaker · Secondary: Removal
Why it scores here
Scarlet Security converts a single card into a full wipe of the opponent's Spell/Trap zone, but only while a face-up "Red Dragon Archfiend" is already on the board, so its value is entirely conditional on the deck's own boss being established. Combos evidence confirms it is never a starter, search target, material, or payoff (0% across all of those roles in 5 appearances), meaning it builds nothing — it only clears the way for a board the deck already made. Its 1-of inclusion in 377 of 400 decks and 100% Resonator inclusion show it is a cheap, real tech slot rather than a power engine. Its 0 ATK/DEF and card-text length earn no points here; the score reflects conditional backrow removal that is dead in hand without its boss.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 42 | Normal Spell with no search route in evidence and a hard condition requiring you to control "Red Dragon Archfiend", so it is dead without the boss; still run as a 1-of in 377 of 400 decks (observed). |
| Combo & Conversion | 15 | Across 5 combo appearances it is 0% as_starter, as_searched, as_material and as_payoff, adding no bodies or extensions to any line (observed). |
| Resource Economy | 50 | It spends one card to destroy potentially several opponent backrow cards but generates no refuel or repeatable advantage of its own (inferred). |
| Effect & Interaction | 55 | Card text destroys ALL Spell/Trap Cards the opponent controls once the condition is met — potent against backrow-heavy boards, but it removes no monsters and provides no negation (verified). |
| Material Utility | 5 | It is a Spell Card with no Level, ATK/DEF or attribute, so it converts to nothing as material and contributes nothing when its effect is blanked (verified). |
| Resilience & Flexibility | 28 | Dead in hand without "Red Dragon Archfiend" on field and blanked by a single activation negate; it has no Graveyard, multi-zone or multi-turn utility (inferred). |
| Deck-Building Efficiency | 58 | It costs exactly one slot, imposes no locks or extra garnets, and 94% of decks run precisely 1 copy, so redundancy pressure is near zero (observed). |
Calculation
Weight profile: 0.7 Board breaker/Going-second + 0.3 Removal. Intrinsic ≈ 46, Deck ≈ 51, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- One card destroys the opponent's entire Spell/Trap zone when the condition is met
- Near-free deck slot: 1 copy in 94% of decks, no locks and no extra garnets
- Native fit with Resonator / Red Dragon Archfiend decks that already build the required boss
- Punishes backrow-heavy and control-leaning opponents when going second
Weaknesses
- Completely dead without a face-up "Red Dragon Archfiend" — a hard condition on a Spell
- No search route to it in the evidence, and only 1 copy is normally played
- Removes no monsters and provides no negation, so it does nothing against monster-based boards
- Poor early-game topdeck going first and easily blanked by a single activation negate
Counters / choke points
- Negating its activation (e.g. Solemn Judgment or a Spell-negation trap)
- Removing "Red Dragon Archfiend" before Scarlet Security resolves
- Decks that rely on few or no Spell/Trap cards, leaving the wipe with no targets
- Hand traps that stop the Resonator line before it produces the required boss
Best use
One-of backrow board-breaker tech alongside the deck's own Red Dragon Archfiend boss. Decks: Resonators, Red Dragon Archfiend / Archfiend. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Spell; if you control "Red Dragon Archfiend", destroy all Spell and Trap Cards your opponent controls; Card is a Normal Spell with 0 ATK/DEF and no Level, therefore unusable as material; Legal in TCG, OCG, Master Duel and Duel Links (formats field)
- Observed: 400 of 400 tracked decks run it in the Main Deck (0 in Side), average 1.08 copies, max 3; Copy distribution skews to a single copy: 377 decks at 1, 16 at 2, 7 at 3; 19 distinct archetypes listed, dominated by Resonators (50%) and Archfiend (17.5%); Usage statistics show 100% inclusion at 1 typical copy in Resonators; 5 combo appearances (100% of tracked combos) with avg_power_index 100 and avg_starter_count_when_present 0.8; In those combos it is 0% as_starter, as_searched, as_material, as_payoff, in_end_board and in_end_hand
- Inferred: It is live only after the deck commits a Red Dragon Archfiend to the field, making it a conditional board-breaker rather than a standalone removal spell; It is a going-second/backrow-clearing tech rather than a combo or resource engine; Because it is a 1-of with no evidence of a search route, drawing it before the boss exists is a functional dead card
- Data gaps: no banlist token — assumed 3 copies (unlimited) combos_evidence lists role_in_combo empty for all 5 appearances, so the card's precise combo function is not machine-labeled no data on how often a Red Dragon Archfiend is on field when Scarlet Security is drawn no dated metagame snapshot, so meta_power is null/provisional
