Straight Flush — Power Evaluation
Final Score: 48 ± 6 · Confidence: Medium
- Intrinsic: 51 · Deck: 46.6 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Board breaker
Why it scores here
Straight Flush converts a single activation into up to five destroyed opponent Spell/Trap cards, which earns real resource and interaction value, but only when the opponent's Spell & Trap Card Zones are all occupied. That activation condition is the dominant factor: it makes the card dead in many boards, so its score is held near the middle. Its 17-deck inclusion across nine archetypes confirms it is a practical, portable pick, but that frequency is not counted as power. It has no body and no recorded combo role, so material and combo axes contribute almost nothing.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | A face-down trap with no searcher in the evidence, live only when drawn and only against a full opposing S/T row (text + deck data: 17 decks, 1.65 avg copies) (verified). |
| Combo & Conversion | 15 | No combo data exists, and the text builds nothing on its own; it is a removal effect, not a board-building one (inferred). |
| Resource Economy | 65 | Text allows one card to destroy up to five opposing S/T cards when the condition holds, a strong card-advantage swing, but it spends the trap itself (verified text, inferred net value). |
| Effect & Interaction | 45 | Mass S/T destruction is strong, yet the all-zones-full condition is hard to meet and makes the effect situational (verified text). |
| Material Utility | 0 | A Trap card, so it cannot be used as material or as a name/level provider (verified card type). |
| Resilience & Flexibility | 35 | Activation is one trap action that can be negated, and it depends on the opponent keeping every zone full; there is no redundancy within the card (inferred). |
| Deck-Building Efficiency | 60 | Cheap to run in 1-3 copies with no garnets, but a dead card in boards where the opponent's S/T row is not full (observed copies distribution + inferred dead-draw risk). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Board breaker. Intrinsic ≈ 51, Deck ≈ 46.6, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- One activation can destroy up to all five opposing Spell & Trap cards
- Low-cost to run: 1-3 copies, no garnet or lock restriction
- Broadly portable across nine archetypes and four gameplay types
Weaknesses
- Hard activation condition: all of the opponent's Spell & Trap Card Zones must be occupied
- Dead against an opponent who keeps even one S/T zone empty
- No body and no combo role, so it contributes nothing as material or a starter
Counters / choke points
- Opponent keeping at least one Spell & Trap Card Zone empty (inferred from the activation condition)
- Negation of the activation by an opposing trap (inferred from card type)
Best use
Conditional mass Spell & Trap removal answer for boards where the opponent's S/T row is full. Decks: Rose Dragon, Egyptian God. Suggested copies: 2.
Evidence & gaps
- Verified: Activation requires all of the opponent's Spell & Trap Card Zones to be occupied (card text); Effect destroys all cards in the opponent's Spell & Trap Card Zones (card text); Card type is Trap (card identity); Appears in 17 of the sampled decks, 17 main and 0 side (deck data)
- Observed: Average 1.65 copies per deck; 11 decks run 1 copy, 5 run 3 (copies per deck); Spans 9 archetypes and 4 gameplay types, led by Rose Dragon (5 decks) (deck data); Co-occurs most often with Book of Moon (41%), Polymerization (35%), Monster Reborn (35%) (top partners)
- Inferred: The activation condition makes the card dead in boards with an open opponent S/T zone; Net card advantage is high when the condition is met, but the card itself is spent; Co-occurring staples like Book of Moon and Polymerization reflect generic deck staples, not evidence of power for this card
- Data gaps: No combos supplied: combo conversion is text-only inference No guides supplied No usage statistics (StatisticsCard): archetype inclusion inferred from the 17-deck sample only No measure of how often opponents fill all Spell & Trap zones, so activation frequency is unknown No rulings or banlist token; assumed 3 copies (unlimited)
