Dragonmaid Deck #770649 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 45/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: master-duel

Legality

Main 40 / Extra 14 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck Dragon boss (Dragonmaid Sheou, Lubellion, Zombie Vampire, Filia Regis, Chaos Angel) reached through the Dragonmaid engine; Bystial and Rokket Dragon beaters recycled from hand, GY and banishment
• Turn 1 (going first): Chamber Dragonmaid search for a Dragonmaid Spell/Trap (Hospitality, Changeover, Tidying), then Changeover Fusion Summon into a Dragon boss
• Turn 2 (going second): Hand-trap the opponent's first engine (Ash Blossom, Droll and Lock Bird, Maxx C, Nibiru) and rebuild through Chamber and Changeover
• Recovery: Changeover recovers from the GY and Chamber can return to hand to Special Summon a Level 7+ Dragonmaid; Bystial monsters re-Special Summon by banishing LIGHT or DARK monsters from the GY
• After siding: None: side count is 0 and Master Duel has no sideboard

Why it scores here

The deck opens a functional plan reasonably often: 11 searcher-text cards and 10 archetype-core copies give about 78% odds of at least one core card in a 5-card opening, though Chamber Dragonmaid alone is only about 34% in a going-first hand. Conversion depends on Dragonmaid Changeover and the Extra Deck, with a strong closing set of Dragon bosses (Sheou, Zombie Vampire, Filia Regis, Lubellion). Interaction is dense (6 hand traps, 11 removal-text cards, 2 negation-text cards), and several Bystial and Rokket routes give independent recovery. The score is held down by low archetype purity (22% exact-name), 42 off-archetype copies that do not feed the Dragonmaid engine, the absence of 100%-inclusion core cards (Parlor Dragonmaid, Dragonmaid Lorpar) and the lack of any combo, win-rate or sideboard data; popularity earned no points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53.6, Going First ≈ 50, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine conflicts / low purity (-3); no post-side plan (-2); missing 100%-inclusion core (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers(-7); Meta provisional (no dated sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Dense interaction: 6 hand traps, 11 removal-text cards and 2 negation-text cards
• Strong Dragon boss density in the Extra Deck with ATK 2500 to 3500
• Redundant starters through Chamber, Changeover, Magnarokket and Bystial GY/banish routes
• Legal in Master Duel with copy limits respected

Weaknesses

• Low archetype purity (22%) with many off-archetype Mulcharmy and Rokket cards
• Missing Parlor Dragonmaid and Dragonmaid Lorpar, which usage stats show at 100% inclusion
• No sideboard, so no post-side adaptation
• Chamber Dragonmaid is only about 34% in a going-first opening hand

Critical choke points

• Chamber Dragonmaid access (3 copies, about 34% per opening hand)
• Dragonmaid Changeover as the main Fusion enabler (1 copy)

Recommended changes

Evidence & confidence

• Verified: Legal in Master Duel: 40 main, 14 extra, 0 side; all restricted cards within legal copies; Extra Deck composition: 9 Fusion, 2 Xyz, 2 Link, 1 Synchro; Monster ATK values for the Dragon bosses
• Observed: Usage stats list Parlor Dragonmaid and Dragonmaid Lorpar at 100% inclusion, neither in the list
• Inferred: Chamber Dragonmaid opening odds and archetype-core consistency from hypergeometric estimates; Engine coherence and resilience reads from card text; Going-first and going-second estimates
• Provisional: Meta power and matchup fit: 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 match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Usage join is inconsistent: House Dragonmaid and Striker Dragon appear in the card list but are flagged in_this_deck false in usage_statistics; the missing-core claim relies only on Parlor Dragonmaid, Dragonmaid Lorpar and Dragonmaid Tinkhec Meta Power is Provisional without a dated metagame sample
