Melodious Deck #767753 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Melodious Fusion and Link boards (Bacha, Flowering Etoile, Schuberta, Bloom Diva, Bloom Prima) built from Pendulum and Summon-from-hand engine pieces, closed by Super Starslayer TY-PHON - Sky Crisis and Luce the Dusk's Dark as large bodies; Fairy and Melodious ATK pumps (Sonata, Elegy, Canon, Aria) for a board-based beatdown once the Fusion boards are live
• Turn 1 (going first): Open a Melodious starter (Sonata, Couplet, Refrain, Soprano, 1st Movement Solo, or Ostinato) and chain it into a Fusion or Link summon using Melodious bodies; use Lightning Storm or Harpie's Feather Duster only when the opponent's board is empty of monsters
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Evenly Matched, Herald of Orange Light, Herald of Purple Light, D.D. Crow, Droll & Lock Bird, or Dark Ruler No More to stop the opponent's first play, then rebuild the Melodious engine from Graveyard recursion (Soprano, Shopina, Couplet, Concerto)
• Recovery: Recover through Graveyard Melodious monsters (Soprano, Shopina) and recursion from Melodious Concerto and 1st Movement Solo, then re-establish a Fusion board from the Extra Deck
• After siding: Not assessable: the Side Deck is empty (0 cards), so there is no post-side plan at all

Why it scores here

The deck is Illegal as submitted: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2, and Herald of Orange Light runs 3 copies against a Limited limit of 1, so the structural score is capped and labelled theoretical only. Structurally the Melodious core is dense (the archetype core group has a 0.98 chance of at least one copy in a 5-card opening hand), so the deck reliably opens a starter and has real Fusion and Link ceilings. Interaction is broad, with 16 hand traps and 19 negation-text cards, which keeps it alive through a first disruption. Its weaknesses are a 43.7% exact-archetype purity, a cluster of narrow situational cards (Harpie's Feather Duster, Lightning Storm, Solemn Accusation, Dark Ruler No More), a single Xyz that has no Level 12 material package, and an empty Side Deck. Popularity and usage stats were not counted as power, and card scores were not averaged into the deck score; the score reflects the system's consistency, interaction, and conversion, and the cap reflects the illegal list.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 59, Going First ≈ 62, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-6); weak post-side plan (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*59 + 0.20*50 - 10 = 47, then capped to 30 because the list is Illegal (Meta Power provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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 Melodious core with a 0.98 chance of at least one core card in a 5-card opening hand
• Broad interaction: 16 hand traps with an 0.88 chance of at least one in a 6-card going-second hand
• Multiple Extra Deck routes (Fusion, Link, Xyz) with high-ATK bodies

Weaknesses

• Illegal as built: copy limits exceeded for Ash Blossom (3 vs 2) and Herald of Orange Light (3 vs 1)
• Empty Side Deck, so no post-game plan
• Low exact-archetype purity (43.7%) with several conditional singleton tech cards
• Super Starslayer TY-PHON has no Level 12 material package

Critical choke points

• Ash Blossom and Herald of Orange Light copy counts must be fixed before the list is playable
• Melodious Fusion Monsters require a Maestra and a second Melodious monster on field, so an early disruption can stall the Extra Deck route

Recommended changes

Evidence & confidence

• Verified: Main deck 56 cards, Extra 15, Side 0 (legal size range 40-60 / 0-15); Ash Blossom copy limit 2 (Semi-Limited) and Herald of Orange Light limit 1 (Limited) exceeded; Core group P(>=1 in hand5) = 0.9789; hand trap P(>=1 in hand6) = 0.8818
• Inferred: Engine accessibility and starter redundancy (D1); Brick risk from conditional singletons and Ty-Phon (D2, D10, D11); Interaction breadth from negation and removal text (D5, D7)
• Provisional: Meta and format fit (D13, Meta Power null)
• Data gaps: No combos supplied: floor, median, and ceiling are text-only inference No tournament link: no meta-share or pilot record No win-rate telemetry in YGOVN Side Deck is empty, so post-side behaviour cannot be evaluated
