Melodious Deck #769609 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 60/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Stun, Fusion/Pendulum/Link
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion and Link end-boards: Flowering Etoile (2800 ATK), Bacha (2500), Schuberta (2400), Bloom Prima (1900, +300 ATK per material) and Bloom Diva, backed by the Pendulum-enabled Melodious starter set.; Xyz pressure through Super Starslayer TY-PHON (2900 ATK) and Evilswarm Exciton Knight.
• Turn 1 (going first): Open with Ostinato or 1st Movement Solo (both need an empty field), use Refrain and Couplet as the Pendulum pair to reach level 2-8 Melodious monsters, then Fusion or Link into the 2nd-turn board. Hand traps are mostly dead on the first turn.
• Turn 2 (going second): Hold a hand trap (Ash Blossom, Ghost Belle, Ghost Ogre, Nibiru, Effect Veiler, Maxx C, Droll) to interrupt the opponent's first board, then rebuild through Fusion or Link on the next turn.
• Recovery: Recover through Couplet and Soprano searches, Shopina and Soprano GY recursion, Melodious Concerto, and Pot of Prosperity; the Melodious monsters' protection effects (Aria, Elegy) help keep the board alive.
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 play would have to be run with the same 55 cards.

Why it scores here

The deck reliably opens its engine: the four 3-copy starters (Ostinato, 1st Movement Solo, Refrain, Couplet) give roughly an 85% chance of at least one in a going-first opening hand (Inferred hypergeometric estimate). Conversion into a Fusion or Link end-board is plausible but unmeasured, because no recorded boards exist, so combo ceiling and median are text-based reads only. Interaction is dense (15 hand-trap-flagged cards, about 37% of the Main Deck), which lifts going-second and resilience scores, but the same density is the main reason the going-first hand can brick. The score comes from consistency, median output and interaction taken together as one system. Popularity and archetype share did not earn points, no card scores were averaged, and the deck has no side deck, which keeps D12 low.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 60.72, Going First ≈ 58, Going Second ≈ 67, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: engine redundancy (2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*60.72 + 0.20*54 + 1 = 60.4, rounded to 60

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Four 3-copy starters give a consistent going-first opening.
• Dense interaction (Ash, Ghost Belle, Ghost Ogre, Droll, Maxx C, Nibiru, Veiler) covers the going-second turn well.
• Fusion and Link end-boards reach 2500+ ATK with multiple recursion and search routes.

Weaknesses

• 15 hand-trap-flagged cards in 40 slots: many are dead on the going-first turn.
• No side deck, so no post-side adaptation.
• Only 60% exact-name archetype purity, with off-theme tech and splash slots.
• No recorded boards, so the combo ceiling and median cannot be verified.

Critical choke points

• The 12-card starter set on an empty board; without it, the Fusion and Link engine does not start.
• Single copies of Limited cards (Maxx C, Droll, Pot of Prosperity) do not recover if they are lost.

Recommended changes

Evidence & confidence

• Verified: Main 40 and Extra 15 meet the OCG size rules; the Limited and Semi-Limited copy counts are legal.; Composition counts (9 Fusion, 4 Link, 2 Xyz; 15 hand-trap flags; 0 side cards) match the card list.
• Observed: Usage stats: 22 of 25 archetype core cards present (the 3 absent are Herald of Mirage Lights, Herald of Orange Light, Mulcharmy Fuwalos).
• Inferred: Going-first starter probability ~0.85 and full-brick estimate ~0.15 from hypergeometric draws.; Hand-trap density effects on going-first and going-second hands.; Combo ceiling from card text (Fusion/Link ladder).
• Provisional: Meta power is null; matchup fit and tournament reliability need a dated meta sample.; Median output is unknown because no recorded boards exist.
• Data gaps: No recorded combos (total_combos 0): combo floor, median and ceiling are text-only inference. No tournament link: meta-share and per-pilot match records are absent. No win-rate telemetry (going-first/second, matchup or brick rates). Usage statistics mislabel 6 extra-deck core cards as absent (Bacha, Flowering Etoile, Schuberta, Bloom Harmonist, S:P Little Knight, I:P Masquerena): they are in the deck, so the 16/25 core-present figure is too low. The corrected figure is 22/25. Deck title is null and the owner is unnamed, so the list is anonymous. Meta Power is provisional without a dated metagame sample.
