Royal Straight Slasher — Power Evaluation
Final Score: 57 ± 8 · Confidence: Medium
- Intrinsic: 59 · Deck: 55 · Meta: provisional
- Primary role: Board breaker · Secondary: Recovery/Recursion
Why it scores here
The card converts a Royal Straight plus three-Knight shell into a one-activation destruction of every card the opponent controls, and its battle-destruction effect recovers up to three LIGHT Warriors from the Graveyard. Its 2400 ATK and Level 6 body earn nothing on their own. The score is held back by the Special Summon-only restriction, the cost of five hand/Deck monsters at exact Levels 1 through 5, and the absence of any recorded board evidence.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | Royal Straight is the only summon route in the text and appears in 32 of 33 sampled decks, with all three Knights present in 33 of 33 (observed); the GY Knight condition is inferred to be reachable in that shell. |
| Combo & Conversion | 55 | The board-wipe effect is strong if it activates, but there are zero recorded boards, so conversion from a realistic start is text-only inference. |
| Resource Economy | 62 | Sending five monsters as a cost is card disadvantage, offset by destroying all opponent cards and by recovering up to three LIGHT Warriors from the GY (verified text, inferred net value). |
| Effect & Interaction | 65 | Destroying the opponent's entire field is a strong disruption effect when live, but it is gated by a five-monster level requirement and the Knight condition (verified text, inferred strength). |
| Material Utility | 40 | A Level 6 LIGHT Warrior is a reasonable generic material body, but no material role evidence exists and the card cannot be Normal Summoned (verified stats, inferred fit). |
| Resilience & Flexibility | 50 | Battle-destruction recursion gives some recovery across turns, while the GY Knight condition and Royal Straight dependency leave it exposed to interruption (verified text, inferred exposure). |
| Deck-Building Efficiency | 45 | Usually a single copy with the Knights and Royal Straight already staples, but it is a dead brick without Royal Straight and cannot be Normal Summoned or Set (verified text, observed copies). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Recovery/Recursion (rounded to 2 decimals, sums to 1.00). Intrinsic ≈ 59, Deck ≈ 55, Meta = provisional. Modifiers: Self-locking summon restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Destroys every card the opponent controls in one activation once its cost is met (verified text)
- Battle-destruction effect recovers up to three LIGHT Warriors from the GY (verified text)
- Sits in the Royal Straight Knight shell that appears in all 33 sampled decks (observed)
Weaknesses
- Special Summon only, via Royal Straight (verified text)
- Needs Queen's, King's, and Jack's Knight in the GY before the wipe (verified text)
- Needs five monsters at Levels 1 through 5 sent from hand and/or Deck (verified text)
- No recorded board evidence, so conversion is unverified (data gap)
Counters / choke points
- Interrupting Royal Straight before the summon (inferred from the summon condition)
- Denying the GY Knight condition before activation (inferred from the text's requirements)
Best use
Conditional board breaker with LIGHT Warrior recursion. Decks: Royal Straight Knight shell (Queen's, King's, and Jack's Knight with Royal Straight). Suggested copies: 1.
Evidence & gaps
- Verified: Cannot be Normal Summoned or Set; must be Special Summoned with Royal Straight; Effect 1: with Queen's, King's, and Jack's Knight in the GY, send 5 monsters of Levels 1 to 5 from hand and/or Deck to the GY to destroy all opponent cards; Effect 2: when destroyed by battle, Special Summon up to 3 LIGHT Warrior monsters from the GY; Each effect is once per turn; Level 6, LIGHT Warrior, ATK 2400, DEF 1350
- Observed: 33 sampled decks; the card is in all 33 (33 main, 0 side); Royal Straight in 32 of 33 decks; Queen's, King's, and Jack's Knight in 33 of 33; Joker's Knight in 87.9% of decks; 15 distinct archetype rows across the sample; Single copy in 29 of 33 decks, average 1.15 copies
- Inferred: The Knight trio plus Royal Straight is the realistic summon route in practice; Destroying all opponent cards is strong when live, but the level and Knight conditions limit how often it activates; Level 6 LIGHT Warrior is a reasonable generic material body (no material role evidence)
- Data gaps: No combos supplied: combo conversion, starter/material roles, and power index are text-only inference No guides supplied No banlist token; assumed 3 copies (unlimited) No StatisticsCard usage statistics; inclusion inferred from the 33-deck sample only Royal Straight's own card text is not in the evidence pack Activation timing of effect 1 (for example, whether it can be used on the opponent's turn) is not stated in the text Egyptian God appears under two archetype IDs (662 and 358), which may inflate the distinct-archetype count
