Melodious Deck #758784 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 36/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Fusion, Link and Xyz boss monsters from the Extra Deck (Supreme King Z-ARC 4000 ATK, Starving Venom Predapower 3600 ATK, Odd-Eyes Absolute 2800 ATK) reached through Melodious, Supreme King and Odd-Eyes engines; Pendulum Summon chains and Link Summons of Odd-Eyes and Pendulum monsters for board pressure
• Turn 1 (going first): Open with a Pendulum searcher or Ostinato (Fusion Summon from the Extra Deck when you control no monsters), then build toward a Fusion boss while Ash Blossom and Droll protect the line
• Turn 2 (going second): Use the Ash Blossom and Droll hand traps and Horoscope Sorcerer to disrupt the opponent's first board, then rebuild through Pendulum searches and Z-ARC once the Pendulum Zone is set
• Recovery: Melodious Concerto returns to the deck from the GY when a Melodious Fusion Monster hits the GY and draws a card; Pendulum searchers rebuild the Pendulum Zone each turn
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This list is Illegal in OCG: Ash Blossom is run 3 copies against a limit of 2, Droll & Lock Bird 2 against 1, and Called by the Grave and Triple Tactics Talent are Forbidden. Per the legality rule it does not receive a normal score; the figure above is a theoretical, structural-only read capped low. Structurally the deck can open a functional Pendulum searcher on turn 1 (about 96% for the searcher group in a 5-card hand) and its Fusion, Link and Xyz bosses carry high ATK and layered negation text, so the ceiling is real. The median and floor are unmeasured because no combos were recorded, and the wide Pendulum scale spread (1 to 9) plus a 15-card Extra Deck mixing three summon types create engine conflicts that lower consistency. The score comes from consistency, interaction and closing power on the system, not from the Melodious archetype's popularity and not from averaging card scores. The deck has no Side Deck, which caps the adaptability score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54.5, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); engine conflicts (-4); no side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-17); Illegal deck, so theoretical/structural-only and capped low

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Searcher density: 18 searcher-text cards give about 96% at least one in a 5-card opening hand
• Layered interaction: Z-ARC, Odd-Eyes Absolute, Predapower and Ash/Droll cover opponent Fusion, Synchro, Xyz and Link effects
• High-ATK Extra Deck bosses: Z-ARC 4000 ATK and Predapower 3600 ATK give closing power

Weaknesses

• Illegal list: copy-limit and Forbidden violations mean the deck cannot be played as built
• No Side Deck, so there is no post-side adaptability
• Pendulum scale spread and three summon types create engine conflicts and reduce consistency
• Exact-name archetype purity of 21.8% with 43 off-archetype copies

Critical choke points

• Pendulum Zone pair: scales 1-9 mean that only some pairs are live, so the Pendulum route can stall
• Z-ARC requirement: the boss needs Dragon-type Fusion/Synchro/Xyz materials, which the deck does not guarantee
• Forbidden and over-limit cards: Called by the Grave and Triple Tactics Talent cannot be played in OCG

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with Ash Blossom over its copy limit (3 vs 2), Droll over its limit (2 vs 1), and Called by the Grave and Triple Tactics Talent Forbidden; Main 40 and Extra 15 are within OCG size rules; Side is 0; Card text and stats for the listed boss monsters (Z-ARC 4000 ATK, Predapower 3600 ATK, Odd-Eyes Absolute 2800 ATK); Archetype purity 21.8% (12 exact-name copies of 55)
• Observed: Usage stats: Refrain and Ostinato are core cards at 100% inclusion; Droll is core at 88%
• Inferred: P(at least one searcher in 5) = 0.96 and P(at least one hand trap in 6) = 0.58 (hypergeometric); High ceiling from the Fusion, Xyz and Link boss chain (semantic read); Engine conflicts from the Pendulum scale spread (1-9)
• Provisional: Meta Power and matchup fit: no dated meta sample or tournament link; Floor and median output: no recorded boards
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and a per-pilot record are absent no win-rate telemetry exists in YGOVN for going-first/second, matchup or brick rate Meta Power is Provisional unless a dated metagame sample is supplied The list is Illegal, so the score is theoretical and structural-only and is capped low
