Identity & game plan

  • Win condition: Level 7 Dragon Xyz boards (Chasma, Eclipse, Blaze, Undying Legion) built from Dragon Ruler Level 7 monsters recycled from hand and GY; Disaster, Dragon Ruler of All Apocalypses field and GY wipe; Blaze destroys 2 cards per activation; Dark Hole and Heavy Storm as board resets
  • Turn 1 (going first): Spectral (3 copies) or a Lightning/Burner/Reactan discard into a Level 7 Dragon, then Tempest/Blaster/Tidal/Redox from hand or GY into a Dragon Ruler Xyz; Draco-Utopian Aura or Unbreakable Xyz Barrier held up as the only interaction
  • Turn 2 (going second): Dark Hole or Heavy Storm to clear the opponent's board, then Mulcharmy Fuwalos/Purulia draw on each opponent Special Summon and rebuild a Dragon Ruler Xyz; Eclipse and Blaze provide the end-board
  • Recovery: Dragon Ruler Level 7 monsters that return to hand or can be Special Summoned from the GY (Tempest, Blaster, Tidal, Redox) rebuild a board after a wipe; Spectral and Sacred Sword of Seven Stars supply card draw
  • After siding: Not evaluable: the deck runs no Side Deck (side_count 0), so there is no post-side plan

Why it scores here

The deck reliably opens a Dragon Ruler engine: the archetype core has a 0.72 chance of at least one card in a 5-card opening hand, and the searcher group (14 copies) a 0.78 chance, so the line is usually live by turn 2 (Inferred, hypergeometric). Conversion is strong on the system: Level 7 Dragon monsters (Tempest, Blaster, Tidal, Redox) recycle themselves from hand and GY into Chasma, Eclipse, Blaze and Disaster, giving a high ceiling with 2600 to 3000 ATK bodies at the end of the board. Consistency is held back by three cards that do not fit the plan: Lava Golem (3 copies) needs two opposing monsters to Special Summon, Testudo erat Numen blocks the deck's own 1800+ ATK Special Summons, and the Mulcharmy draw engine wants an empty field that Dragon Ruler lines fill. The score comes from engine coherence, median output, and interaction on the system, not from Dragon Ruler being a popular archetype and not from averaging the card scores. The deck runs no side deck and has no hand traps, which caps its interaction and post-side score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 P(>=1 core card in 5-card opening hand) = 0.72; P(>=1 searcher-text card) = 0.78; Spectral 3-copy P = 0.25; Lava Golem and Testudo bricks reduce live-start odds (Inferred)
D2 Opening-Hand Quality & Brick Management 48 Dead or conditional cards: Lava Golem x3 (needs 2 opposing monsters), Eradicator Epidemic Virus x2 (needs a DARK 2500+ Tribute), Testudo x1 (conflicts with own summons), Dragon Shrine x2; full-brick rate not computed (Inferred)
D3 Combo Conversion & Ceiling 70 Level 7 Dragon recursion from hand/GY into Xyz boards with Disaster and Blaze as wipes gives a high ceiling; no parseable boards in combos_evidence, so the ceiling is text-only (Inferred)
D4 Combo Floor & Median Output 52 No recorded boards; redundant 2-copy starters and Ipiria/Spectral lines give a moderate floor, but Xyz-dependent lines lower the median (Inferred)
D5 Interruption Resilience & Route Redundancy 64 Self-recycling Level 7 Dragons (hand and GY returns) and multiple discard-to-search lines give route redundancy after one interruption (Inferred, text-based)
D6 Resource Economy, Recovery & Grind 62 Spectral, Sacred Sword of Seven Stars, Dragon Ravine, Ipiria and Link Apple provide draw/search and GY recovery; Dragon Ravine and Spectral refill hand (Inferred)
D7 End-Board & Interaction Quality 60 Dark Hole, Heavy Storm, Eradicator, Draco-Utopian Aura and Unbreakable Xyz Barrier cover broad interaction; zero hand traps and only 6 negate-text cards (Verified flags / Inferred semantic)
D8 Going-Second & Board-Breaking Power 60 Dark Hole, Heavy Storm, Blaze, Disaster and Eclipse break boards; Mulcharmy draw on opponent Special Summons adds going-second value; Testudo hurts the deck itself (Inferred)
D9 Offensive Pressure & Closing Power 72 Chasma x3 (3000 ATK), Blaze and Blaster (2800), Eclipse and Undying Legion (2700), Tempest (2400); Chasma and Blaze have direct board-control effects (Verified stats / Inferred)
D10 Main Deck Efficiency & Flexibility 55 55 main with 26 distinct cards and 7 three-copy cards; about 17 off-archetype copies (Mulcharmy, Kaiju, Hole, Dragunity, Zombie) and 1-copy tech lower coherence (Verified composition / Inferred)
D11 Extra Deck Efficiency & Coverage 66 15 Extra slots, 8 distinct: 3 Chasma, 3 Eclipse, 2 Blaze, 2 Disaster, 2 Undying Legion, plus 1-of flex; Level 7 Dragon requirement keeps the Xyz set coherent (Verified composition)
D12 Side Deck Adaptability 18 No Side Deck, so no adaptability is possible; score reflects only the absence of a post-side plan (Verified: side_count 0)
D13 Matchup Coverage & Format Fit 50 No tournament link and no dated metagame; archetype meta-share absent, so this score is provisional and weighted only in the Midrange profile (Provisional)
D14 Pilotability & Error Tolerance 45 Multi-step chains (discard, Special Summon, Xyz, banish, recycle), Mulcharmy field-empty decisions and Testudo timing give a high decision load (Inferred)

How the score was computed

Strategy profile: Midrange primary; Combo secondary disclosed, not blended into weights. Structural ≈ 58, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Testudo self-conflict (-2); Dead-card burden (-1); Engine conflict (-1); No side deck (-2); Interaction gap (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*58.08 + 0.20*50 - 7 = 49.5, rounded to 49

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.72 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Level 7 Dragon recursion from hand and GY keeps the Xyz line live after a wipe
  • Chasma, Eclipse, Blaze and Disaster give a high closing ceiling
  • Mulcharmy draw on opponent Special Summons adds going-second value
  • Two-wipe package (Dark Hole, Heavy Storm) plus Disaster and Blaze

Weaknesses

  • Lava Golem x3 is a conditional brick
  • Testudo erat Numen works against the deck's own Level 7 and Xyz summons
  • Mulcharmy draw engine conflicts with Dragon Ruler field presence
  • No side deck and no hand traps

Critical choke points

  • Turn 1 needs Spectral, Lightning, Burner or Reactan plus a Level 7 Dragon; without a Dragon Ruler starter the line stalls
  • Xyz summons need two Level 7 monsters on field; a single removal or negation at the wrong time breaks the board
Priority Remove Add Reason
1 Testudo erat Numen A second Dragon Ruler starter or a hand trap Testudo blocks the deck's own 1800+ ATK Special Summons; the deck needs no anti-summon card
2 Lava Golem (1 copy) Nebulus, Dragon Ruler of Mishaps, the missing core card Nebulus has 55.6 percent usage across the archetype and is absent here; Lava Golem needs two opposing monsters
3 Eradicator Epidemic Virus (1 copy) A Level 7 Dragon or Dragon Ruler Xyz Eradicator requires a DARK 2500+ Tribute that the Main Deck rarely supplies

Evidence & confidence

  • Verified: Legal in OCG: 55 Main, 15 Extra, 0 Side, Heavy Storm Limited at 1 copy; Dragon Ruler core (Tempest, Spectral, Blaster) at 55.6-77.8 percent usage, 5 of 6 core cards present; Composition counts and card text for all 26 Main and 8 Extra cards
  • Inferred: P(>=1 core card in 5-card hand) = 0.72 and searcher group 0.78 (hypergeometric); Recursion and wipe-resilience of Level 7 Dragons; Interaction density and board-breaking ratings; Brick rate from Lava Golem, Testudo and Eradicator
  • Provisional: Meta Power (no dated metagame sample); D13 matchup and format fit
  • Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and pilot match record are absent no win-rate telemetry; going-first, going-second and matchup rates are unknown Meta Power is provisional without a dated metagame sample archetype tags under-report Dragon Ruler (eight Dragon Ruler-named monster types have archetype null)
