Melodious Deck #742016 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion and Link boards built from Melodious monsters (Bacha, Schuberta, Flowering Etoile, Bloom Harmonist) with Shopina/Refrain/Couplet as Pendulum and searcher support; Hand-trap-backed disruption that buys time for a single Melodious board to convert over several turns
• Turn 1 (going first): Open a Melodious starter (Ostinato, Canon, Sonata, Refrain, Couplet, or 1st Movement Solo), search or Special Summon a second Melodious piece, and reach a Fusion or Link monster. Forbidden cards are removed from the plan, so the line runs on the legal cards only.
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Infinite Impermanence, Droll and Lock Bird, Maxx C, Nibiru) to answer the opponent's first combo, then rebuild a Melodious board from the Graveyard and the Extra Deck.
• Recovery: Recursion from the Graveyard through Soprano, Shopina, Couplet, and Melodious Concerto, plus hand-trap redundancy. Recovery is inferred from card text only, since no board data exists.
• After siding: Not supported: the deck runs 0 side cards, so there is no post-side plan. Best-of-3 play is not represented in the evidence.

Why it scores here

The deck's structural score comes from its system: 36 exact Melodious copies plus about 10 Pendulum and searcher effects give P(at least one Melodious monster in an opening hand of 5) of about 0.98 for the core set (Inferred), so the engine is usually reachable on turn 1 or 2. Interaction is dense, with 17 hand traps and 14 negation and removal effects, which supports a respectable going-second score. Offensive power is held back by the lack of recorded boards, the 34 off-archetype copies that can brick, and the absence of a side deck. The score is not an average of the individual card scores and does not reflect the archetype's popularity, since no usage or meta data was supplied. Because the list is Illegal (two Forbidden cards are run), the result is capped at a theoretical, structural-only 30.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary disclosed as context only. Structural ≈ 55, Going First ≈ 54, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); no side deck (-3); Limited key cards (-2). Final formula: Illegal list: raw 0.80*55 + 0.20*45 = 53, plus modifiers -11 = 42, capped to 30 (theoretical, structural-only). Meta provisional.

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

• Melodious core is dense: P(>=1 core card in opening hand) of about 0.98
• 17 hand traps and 14 negation effects give strong going-second interaction
• Multiple independent starters (six) reduce single-choke-point risk
• Extra Deck has 15 cards with both Fusion and Link routes

Weaknesses

• Illegal list: 2 Forbidden copies (Triple Tactics Talent, Dimension Shifter)
• 0 side cards, so no post-side adaptation
• 34 off-archetype copies and generic bricks raise the dead-card rate
• No recorded boards, so the combo floor and median are unverified

Critical choke points

• Forbidden cards must be removed before the list can be played; the replacement cards decide the consistency
• Pendulum and Fusion conversion relies on a Melodious starter being in hand
• Limited single copies (Pot of Prosperity, Heavy Storm, Maxx C, Droll and Lock Bird) reduce recovery if the first one is lost

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 2 Forbidden copies in the Main Deck (Triple Tactics Talent, Dimension Shifter); Main 55 and Extra 15 are within OCG size rules; Ash Blossom and Joyous Spring runs 2 copies, within its Semi-Limited limit; Archetype purity 51.4% exact-name; 0 Side cards
• Inferred: P(>=1 Melodious monster in opening hand) = 0.98 from the hypergeometric table; Hand-trap coverage on going second = 0.90; Interaction density from card text (negation and removal hints); Fusion and Link ceiling from card text
• Provisional: Meta Power (null, no dated meta sample); D13 matchup and format fit (no tournament context)
• 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 for going-first, going-second, matchup, brick or OTK rates Meta Power is Provisional without a dated metagame sample 0 side cards: post-side plan unscored
