Dracotail Deck #766463 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Combo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion boards of 3000-ATK Dragons (Arthalion, Secreterion, Albion, Titaniklad, Khaos) built from Dracotail and Fallen of Albaz material, backed by hand-trap disruption on the opponent's turn.; Dracotail recursion loop: Flame, Horn and Sting each replace the card with a draw while returning a Dracotail from the GY or banishment.
• Turn 1 (going first): Open with a Dracotail or Ecclesia starter (about 99.9% of hands hold a core card), search a Dracotail via Lukias, Ketu or Cartesia, then Fusion Summon from the Extra Deck with Rahu, Branded Fusion or Mululu.
• Turn 2 (going second): Hold Ash Blossom, Maxx C, Effect Veiler or Mululu for the opponent's first summon or activation (about 58% of six-card hands hold a hand trap), then rebuild a board through the GY Fusion triggers.
• Recovery: Recycle Dracotail monsters from the GY (Phryxul, Lukias, Fallen of the White Dragon) and use the Flame/Horn/Sting card-replacement effects to refill the hand after a disruption.
• After siding: Not applicable: Master Duel is played best-of-one with zero Side Deck cards, so there is no post-side plan to evaluate.

Why it scores here

The deck reliably opens a functional plan: the Dracotail and Ecclesia starters are present in almost every opening hand, and about 99.9% of 5-card hands hold at least one core card, so the engine comes online without a special hand. Its real ceiling is the Fusion board of 3000-ATK Dragons, but the Fallen of Albaz route depends on only three access cards (Albaz plus two White Dragons), so about two-thirds of going-first hands lack that route, which caps consistency. Disruption is layered: five hand traps, roughly seven negation texts and ten removal texts give the deck a real answer to a first board, and the Flame, Horn and Sting replacement effects keep card flow going. The score comes from consistency, interaction and recovery considered together across the system, not from averaging card scores or from Dracotail's popularity, which only confirms the list is real and accessible. Going-first and going-second power are close because the deck is built to act on the opponent's turn, and the lack of combo boards and matchup data keeps the median and meta reads provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: banlist exposure (-1); engine conflicts (-1); unrecoverable choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample)

Probability & combo summary

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

Strengths

• Core starter presence is nearly guaranteed (0.9988 in opening 5).
• Five hand traps and about seven negation texts provide layered interaction on the opponent's turn.
• Dracotail replacement effects (Flame, Horn, Sting) keep card flow going after disruption.
• Multiple independent starter families (Dracotail, Ecclesia, Albaz) give redundancy.

Weaknesses

• Fallen of Albaz route has only three access cards, leaving about two-thirds of going-first hands without it.
• Ten Tuner monsters support only one Synchro, so much of the Tuner typing is wasted.
• Mulcharmy Fuwalos needs an empty hand to function and is a dead card in many hands.
• No Side Deck cards, so no adaptation option.
• Several once-per-turn and Extra Deck summon restrictions make sequencing error-prone.

Critical choke points

• Fallen of Albaz access (3 cards) for the 3000-ATK Albaz fusions.
• Single-copy Limited cards (Branded Fusion, Rahu Dracotail, Dracotail Lukias) that gate Fusion routes.

Recommended changes

Evidence & confidence

• Verified: Legality: 40 Main / 15 Extra / 0 Side within the Master Duel size rules; all 9 restricted cards within legal copy limits.; Card text and banlist status from the card records.; Archetype usage stats: core cards at 100% inclusion for several Dracotail cards.
• Inferred: Opening-hand hit rates from hypergeometric probabilities.; Ceiling read from Fusion card text and 3000-ATK boards.; Interaction density from role flags and negation/removal text.; Pilotability and sequencing error rate from restriction text.
• Provisional: Meta Power is null: no dated metagame sample exists.; Matchup fit (D13) and side-deck score (D12) are Provisional.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference (combos_evidence total_combos 0). No tournament link: archetype meta-share and per-pilot match record are absent. No win-rate telemetry exists in YGOVN (going-first/second, matchup, brick and starter rates): these signals are Inferred or Unknown. Usage statistics disagree with the card list: in_this_deck is false for Dracotail Gulamel, Dracotail Arthalion and Secreterion Dragon, though all three appear in the deck's Extra Deck, so core_present_pct (64) and missing_core are unreliable. Meta Power is Provisional unless a dated metagame sample is supplied.
