Dragon Ruler Deck #771613 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Xyz/Synchro
• Format: ocg

Legality

Main 45 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck Xyz/Synchro boss (Chasma 3000 ATK, Disaster, Eclipse, Bystial Dis Pater 3500 ATK) reached through the Dragon Ruler Level 3/4 to Level 7 Special Summon chain; Armed Dragon Thunder LV7 and Pile Armed Dragon (2800 ATK each) and the Synchro/Xyz bosses from the Extra Deck
• Turn 1 (going first): Open a Dragon Ruler starter (Burner, Lightning, Stream, Reactan, Spectral, Here There Be Dragons) and convert it into a Level 7 Dragon Ruler (Blaster, Tempest, Tidal, Redox) that then Xyz or Synchro Summons a boss
• Turn 2 (going second): Same chain through the opponent's board, relying on Extra Deck negates (Bystial, Ruddy Rose Dragon, Arms of Genex Return Zero) and Eclipse; main-deck interaction is thin and the deck has no sideboard
• Recovery: Recover through Here There Be Dragons and Spectral from the GY and banishment, plus Dragon Ruler recursion effects that return monsters to the hand or Deck
• After siding: None: the deck has zero Side Deck cards, so there is no post-side plan to evaluate

Why it scores here

The deck reliably opens a Dragon Ruler starter: the archetype core group (15 copies) has P(at least one in a 5-card opening hand) of about 0.88, and the searcher group (19 copies) about 0.95 (both Inferred from hypergeometric estimates). Level 3/4 Dragon Rulers (Burner, Lightning, Stream, Reactan) discard themselves to Special Summon Level 7 Dragon Rulers, which then feed Extra Deck Xyz and Synchro bosses with 2800 to 3500 ATK, so closing power is high. Conversion, median output and going-second strength could not be measured because no recorded boards exist, so those scores are text-based inference with wide uncertainty. The list is only 16.7 percent exact-name Dragon Ruler, with Armed Dragon, Rose, Doriado, Genex and Swordsoul cards diluting the engine, and Testudo erat Numen (no Special Summon of 1800 ATK or more for either player) directly conflicts with the deck's own 2400 to 3000 ATK Special Summons. The deck has no sideboard, which caps adaptability. Popularity is not credited: the six core usage cards being present confirms the list is real, not that it is strong, and the score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflict (-5); engine compactness (-3); weak post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 60.8 gives 59.1 before modifiers; modifiers -10 give 49

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dragon Ruler starter chain (Burner, Lightning, Stream, Reactan into Blaster, Tempest, Tidal, Redox) is 2 to 3 copies per link, giving redundant openings
• High Extra Deck closing power: Bystial 3500, Ruddy Rose 3200, Chasma 3000, ZEUS 3000
• Searcher and recursion text is dense: 19 searcher-text cards and Here There Be Dragons plus Spectral for recovery
• Archetype core is intact: all 6 usage-core cards are present in the list

Weaknesses

• No side deck: zero post-side adaptation for best-of-3
• Engine conflict: Testudo erat Numen blocks the deck's own 1800+ ATK Special Summons
• Low archetype purity (16.7 percent exact name), so Armed Dragon, Rose, Doriado and Swordsoul cards dilute the engine
• Main-deck interaction is thin with no hand traps; the Extra Deck carries the negates

Critical choke points

• Starter access: the 2-copy Level 3/4 Dragon Rulers are each about 0.21 to hit in a 5-card hand alone
• Testudo erat Numen, if drawn with the Extra Deck bosses, blocks their Special Summon

Recommended changes

Evidence & confidence

• Verified: Legal status, 45 Main, 15 Extra, 0 Side against OCG size rules (40 to 60, 0 to 15, 0 to 15); All 6 archetype usage-core cards are present; Testudo erat Numen text: neither player can Special Summon monsters with 1800 or more ATK; Printed ATK and level for Dragon Ruler bosses and Level 3/4 starters
• Inferred: P(at least one archetype-core card in a 5-card opening hand) about 0.88 from hypergeometric estimates; Engine chain feasibility and redundancy from card text; Interaction quality read from Extra Deck text
• Provisional: Meta power is null; no dated meta sample is supplied; Matchup fit and tournament reliability depend on the provisional matchup read
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry (going-first or second, matchup, brick or starter rates) Meta Power is provisional unless a dated metagame sample is supplied Deck title is null in the export
