Dragon Ruler Deck #770255 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Midrange, Combo
• Format: ocg

Legality

Main 60 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion and Xyz extra-deck boards (Dracotail, Dragonmaid, Dragon Ruler, Light and Darkness Dragon fusions) backed by Dragon-type recursion; Kaiju board-control summons (Kumongous, Jizukiru, Interrupted Kaiju Slumber) and Dragon Ruler Level-7 chains
• Turn 1 (going first): Opening searchers (Kitchen/Chamber Dragonmaid, Dracotail Lukias, Ketu Dracotail) toward a Fusion or Xyz starter; the opening-hand hit rate for any single starter is low (see probabilities)
• Turn 2 (going second): Hand traps (Skull Meister, D.D. Crow) and Twin Twisters / Swords of Concealing Light to interrupt, then a Fusion/Xyz rebuild; no side deck to adjust
• Recovery: Recursion from the GY and banishment: Spectral and Dragon Ruler monsters, Dragonmaid Changeover and Tidying, Dracotail Horn and Sting
• After siding: Not supported: side deck is empty (side_count 0), so there is no post-side plan in the evidence

Why it scores here

This is scored on the system, not on an average of its cards, and the score is capped low because the list is illegal: Rahu Dracotail is run 2 copies against an OCG limit of 1. The 60-card main mixes four engines (Dragonmaid 22 copies, Dracotail 13, Dragon Ruler 15, Kaiju 6) on top of Dragon-type staples, so the exact archetype name covers only 7 of 68+7 archetype-tagged copies (9.3% purity). The deck reliably reaches a searcher (about 89% chance of at least one searcher-text card in the opening 5), but the core archetype group opens only about 47% of the time, so the opening engine is inconsistent. Its extra-deck coverage (12 Fusion and 3 Xyz) and the spread of high-ATK boards give real closing power. Popularity and archetype usage stats confirmed the list is real, but they added no points, and the empty side deck and missing combo data keep the confidence Low.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 48, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-5); Engine conflicts (-4); Weak post-side plan (-2). Final formula: Illegal cap applied: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49; modifiers -11 → 38; capped at 30 as theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.23 · 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

• Four-engine searchers reach an engine card in most openings (about 89% for a searcher-text card in hand 5)
• Dense Fusion/Xyz extra deck with high-ATK bodies gives closing power
• Layered interaction: five hand traps plus negation and removal text cards

Weaknesses

• Illegal list: Rahu Dracotail is over the OCG copy limit
• Four engines with about 9% exact-name purity dilute starter density
• No side deck, so no post-side adaptation
• Core archetype group opens only about 47% of the time

Critical choke points

• Rahu Dracotail copy limit: the list cannot be played as built until one copy is removed
• Dracotail/Dragonmaid Fusion materials: many fusions need specific material sets from hand or field
• Single-copy Limited cards (Dracotail Mululu, Ketu Dracotail) as searcher and engine starters

Recommended changes

Evidence & confidence

• Verified: Legality: Rahu Dracotail 2 copies vs OCG Limited limit of 1 (Illegal); Main 60 and Extra 15 are within size rules; Side 0 within the 0–15 range; Banlist statuses for Mululu, Ketu, Rahu (Limited), Arthalion and Lukias (Semi-Limited); Archetype spread and exact-name purity 9.3% from composition
• Observed: Usage stat: Dragon Ruler Storms (inclusion 86%) and Blaster (57%) are archetype core cards, both present
• Inferred: Starter and core hit rates from hypergeometric draw odds; Engine conflicts and brick risk from text and composition; Structural scores across the 14 dimensions and the going-first/second estimates
• Provisional: Meta Power and matchup fit (D13): no dated metagame sample or tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first/second, matchup or brick/starter rates Meta Power is Provisional unless a dated metagame sample is supplied Side deck empty: no post-side performance or adaptability data Deck title is null in the export
