Melodious Deck #767089 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Melodious Fusion and Link monsters (Bacha, Schuberta, Flowering Etoile, Bloom Harmonist) built from Melodious starters such as Canon, Sonata, Couplet, Refrain, 1st Movement Solo and Ostinato.; Fairy Link beatdown through Hip Hoshiningen, Herald of Mirage Lights and Protector of The Agents - Moon, with the Fairy ATK boosts from Sonata and Elegy.
• Turn 1 (going first): Turn 1: Ostinato or 1st Movement Solo for a Level 4 or lower Melodious, then Canon or Sonata to reach a Fusion or Link. The Fusion and Link Extra Deck stock is large enough to carry the plan.
• Turn 2 (going second): Hold Ash Blossom, Droll and Lock Bird, Maxx C, Ghost Belle and Ghost Ogre to stop the opponent's first draw or summon, then start the Melodious engine from the hand traps and starters that survive.
• Recovery: Soprano and Couplet return Melodious monsters or Spell/Traps from the Deck or Graveyard. Concerto recurs from the Graveyard after a Melodious Fusion Monster goes there.
• After siding: Not evaluable. The side deck is empty, so there is no post-side plan. The deck cannot be assessed for best-of-3 use.

Why it scores here

The deck is scored as a system on consistency, engine cohesion, interaction, resilience and turn order, not as an average of its cards. Its Melodious core (36 exact-name copies) makes at least one engine starter likely in the opening hand, and the 15-card Extra Deck gives it a broad set of Fusion and Link targets. Its 17 hand traps and 15 negation-text cards give it strong interaction, especially going second, where the probability of at least one hand trap in a six-card hand is about 0.90 (Inferred). The score is held down by two Forbidden copies of Triple Tactics Talent, which make the list illegal and cap the score at 30, and by the empty side deck, which leaves no post-side plan. Popularity and archetype share were not counted, because no tournament link was supplied and archetype usage only confirms the list is typical.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.7, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12). Final formula: Legality cap applied: the list is Illegal (2 Forbidden copies), so the score is capped at 30 and labelled structural-only. Uncapped: 0.80*61.7 + 0.20*45 - 12 (banlist exposure) = 46.4, which is then capped to 30. Meta Power is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · 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 starter density: 36 exact-name copies make at least one engine starter in the opening hand very likely (about 0.9955 for the core group).
• Broad layered interaction: 17 hand traps, 15 negation-text cards, plus Heavy Storm, Feather Duster and Crossout Designator.
• Strong going-second hand-trap coverage (about 0.90 that a six-card hand holds one).

Weaknesses

• Illegal as built: 2 copies of the Forbidden Triple Tactics Talent.
• No side deck, so no post-side plan and no best-of-3 adaptation.
• Off-archetype load: 34 of 85 archetype-linked copies are off-archetype, and 20 main-deck slots are generic level-0 spells and traps.
• Hand-trap-heavy hands can be dead without an engine starter.

Critical choke points

• Melodious Fusion and Link summons depend on Canon, Sonata, Couplet, Refrain and 1st Movement Solo as starters.
• Triple Tactics Talent is Forbidden, so the list cannot be played as built until both copies are removed.

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within OCG size rules (40-60, 0-15, 0-15).; Triple Tactics Talent is Forbidden in OCG and is run at 2 copies, which is illegal.; All other Limited and Semi-Limited copy counts are legal.; Composition counts: 36 exact Melodious copies, 17 hand traps, 15 negation-text cards.
• Inferred: Starter probabilities from the hypergeometric draw table.; Interaction quality from hand-trap and negation text.; Going-second hand-trap probability of about 0.90.
• Provisional: Meta Power (null) and D13 format fit, because no tournament link or dated sample was supplied.
• 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 are absent. No win-rate telemetry (going-first or second, matchup, brick or starter rates). No side deck: post-side performance cannot be assessed. Meta Power is Provisional because no dated metagame sample is supplied.
