Dracotail Deck #770307 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±6 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Combo, Fusion
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon a 3000-ATK boss (Arthalion, Albion the Sanctifire Dragon, Mysterion, Mirrorjade, Secreterion) from the Extra Deck, usually through a Dracotail or Fallen of Albaz fusion line.; Disruption-led value: hand traps and Dracotail backrow (Sting, Flame, Gulamel) strip the opponent's board, then a fusion boss closes.
• Turn 1 (going first): Open on Faimena, Ketu, Mululu, or Fallen of the White Dragon, search or fusion-summon a boss, and keep Ash, Veiler, or Droll up for the opponent's turn. Turn-1 hand traps are mostly dead on the going-first turn.
• Turn 2 (going second): Hold 6 cards, pass with Ash, Veiler, Ghost Ogre, Droll, Maxx C, or Nibiru to blank the opponent's first summon or fusion, then fuse on your own turn.
• Recovery: Dracotail GY effects (Urgula, Lukias, Phryxul, Pan) re-add or special-summon Dracotail monsters, and Mululu, Faimena, and Ketu restart fusion access.
• After siding: No side deck in Master Duel (side = 0), so there is no post-side plan; adaptation is limited to the Extra Deck boss chosen.

Why it scores here

The deck reliably opens a functional line because about 13 copies that start from the hand (Faimena, Ketu, Mululu, Fallen of the White Dragon, Albaz, Lukias, Phryxul, Ecclesia) give roughly 0.87 odds of at least one starter in a 5-card going-first hand (Inferred hypergeometric). It converts that into pressure through a broad Extra Deck of 3000-ATK fusion bosses, but no recorded boards exist, so the ceiling rests on text reads. Its interaction is the strongest part of the system: 12 hand traps, several negation and removal effects, and boss protection (Albion Sanctifire, Brigrand) make it hard to close out on the opponent's turn. Its weak points are the single Fallen of Albaz body pool that gates six or more Extra fusions, a 30% exact-archetype purity that signals engine conflicts, and no side deck to adapt. Popularity and archetype usage confirm the list is real and accessible but did not add points, and card scores were not averaged into this result.

Dimension scores

How the score was computed

Strategy profile: Control (D13 dropped, meta-neutral, renormalised over 93). Structural ≈ 65, Going First ≈ 62, Going Second ≈ 72, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: engine conflicts (-2); unrecoverable choke point (-2). Final formula: 0.80*Structural(65.1) + 0.20*TournamentReliability(57) = 63.5, then modifiers -4 = 59.5 -> 59 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · 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: 12 hand traps plus negation and removal text on Dracotail backrow and Gulamel
• Multiple independent starters and recursion from the GY, so one interruption does not end the turn
• Extra Deck with several 3000-ATK bosses and protected boss options (Albion Sanctifire, Brigrand)

Weaknesses

• Fallen of Albaz body pool is only three copies across six or more Extra fusions
• Exact archetype purity is 30%, so engines compete for slots
• No side deck; the deck cannot adapt between games
• Hand traps are dead on going-first turn 1

Critical choke points

• Fallen of Albaz / Fallen of the White Dragon as fusion material for Branded Fusion, Albion Sanctifire, Brigrand, Mirrorjade, Devours Dogma, and Albion Branded
• Single-copy Branded Fusion and Branded in High Spirits for the Branded fusion route

Evidence & confidence

• Verified: Legal in Master Duel: main 41 (40-60), extra 15 (0-15), side 0 (0-15); no violations; Restricted copies at or below legal_copies for all 10 Limited and Semi-Limited cards; Archetype purity 30.4% exact; 17 Dracotail-named copies; Guide 1253 describes the deck as a control deck built on hand-trap and backrow resources
• Observed: Usage statistics: Dracotail core cards at 100% inclusion (Rahu, Maxx C, Ash, Mululu, Faimena)
• Inferred: P(>=1 starter in 5-card going-first hand) about 0.87; Consistency and brick estimates from hypergeometric and text reads; Interaction density and boss closing power from card text; Going-first and going-second splits from hand-trap timing and boss access
• Provisional: Meta Power (null) and matchup/format fit (D13 neutral 50); Going-second board breaking depends on a sample of recorded boards
• Data gaps: No recorded combos supplied (combos_evidence.total_combos = 0) - combo floor, median and ceiling are text-only inference No tournament link - archetype meta-share and per-pilot record absent No win-rate telemetry - going-first, going-second, matchup and brick rates are Inferred usage_statistics.in_this_deck reads false for Extra-Deck cards the cards list shows in this deck (Dracotail Arthalion, Dracotail Gulamel, Secreterion Dragon, Rindbrumm, Ecclesia and the Dark Dragon, Mirrorjade, The Dragon that Devours the Dogma); core_present_pct (64%) is therefore understated and the cards list was used instead Meta Power is Provisional unless a dated metagame sample is supplied
