Melodious Deck #773277 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fusion and Link boards led by Darklord and Melodious Fusion Monsters (The First Darklord, Darklord Eveningstar, Bacha, Flowering Etoile) and Darklord Morningstar, Ixchel and Gulgolet; Herald and Mulcharmy interaction-driven tempo; hand-trap negations protect the starter
• Turn 1 (going first): Open with Refrain or Ostinato as a starter, use Darklord Gulgolet and Djehuty searches to reach Darklord Fusion or Link material, and hold Ash Blossom and Droll for the opponent's first activation
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Herald of Orange Light, Droll and Lock Bird) to stop the opponent's board, then rebuild through Darklord Dance and Darklord Contact
• Recovery: Darklord Contact and Banishment of the Darklords recover Darklord monsters from the GY; Ostinato and Melodious Concerto recur through the Melodious engine
• After siding: No Side Deck is registered (side count 0), so there is no post-side plan to evaluate

Why it scores here

The deck is scored as a system, not as an average of its cards. Its core Darklord and Melodious engine is reasonably reachable: the archetype core group has about a 72% chance of at least one card in a 5-card opening hand, and searchers reach about 81% (Inferred). Interaction is dense, with about 13 hand traps and 19 negation-text cards, which gives the deck real endboard and going-second value. Conversion is text-only because no recorded boards exist, so the ceiling (Darklord and Melodious Fusion/Link boards) and the median are both Inferred and kept separate. Popularity was not credited: the archetype share is unavailable, and the 12 core Darklord cards are present but not evidence of strength. The deck is Illegal (three cards over their copy limits), so the score is capped low and this evaluation is structural-only; the deck has no Side Deck, which lowers adaptability.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (Limited / Semi-Limited copies over limit) (-4); no side deck (-2). Final formula: Structural 53.8 (Midrange profile) → Final = 0.80*Structural + 0.20*TournamentReliability = 52.2 before legality; Illegal cap applied: theoretical/structural-only, final capped at 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · 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 hand-trap and negation coverage for both going-first and going-second turns
• Strong Darklord and Melodious Fusion/Link payoff set with 3000 ATK closers
• Searcher and recursion text supports a reasonable resource grind

Weaknesses

• Three cards exceed their copy limits, so the list is Illegal as built
• No Side Deck: no post-side adaptation
• Low archetype purity (15.7% exact-name) splits the engine across Darklord, Forbidden, Herald and Mulcharmy

Critical choke points

• Darklord and Melodious starters: about 28% of opening hands have no core starter (Inferred)
• Fusion and Link payoffs depend on specific Extra Deck copies (Solemn, Eveningstar limited to 1 copy each in practice)

Recommended changes

Evidence & confidence

• Verified: Copy-limit violations for Ash Blossom, Herald of Orange Light and Super Polymerization; Main 55 and Extra 15 are within size rules; Side 0 is legal size; Card stats and text for all listed cards
• Inferred: Hypergeometric starter, searcher and hand-trap estimates; Combo ceiling and median read from card text only; Interaction density read from text roles
• Provisional: Meta power and format fit (no dated metagame sample); Side-deck adaptability (no post-side data)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal: score is capped and structural-only No Side Deck registered
