Melodious Deck #769229 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion and Link boards from Melodious Maestra and Diva monsters (Bacha, Schuberta, Flowering Etoile, Bloom Prima, Bloom Diva), backed by Pendulum Songstress searchers and Link Monsters.; Nibiru, the Primal Being as a Tribute-and-Special-Summon board breaker after the opponent summons 5 or more monsters.
• Turn 1 (going first): Open a Pendulum or 1st Movement Solo starter (P(>=1 of a 3-copy card in 5 cards) = 0.245 each, core group 0.992 to open at least one core card), use Ostinato or 1st Movement Solo to reach a Melodious Fusion or Link, and hold Ash Blossom, Ghost Ogre and Effect Veiler for responses.
• Turn 2 (going second): Use the six-card hand (P(>=1 hand trap) = 0.936) to negate the opponent's first starter or summon, then rebuild with the Melodious Fusion/Link line from the Extra Deck.
• Recovery: Melodious Concerto and Couplet the Melodious Songstress recover a Melodious spell or monster and Soprano and Shopina recover Melodious and LIGHT Fairy monsters from the Graveyard, so the line can restart after a hand trap.
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan.

Why it scores here

The Melodious core is well represented: 34 archetype copies give a 0.992 chance of opening at least one, so the engine is usually reachable on turn 1 (Inferred). Interaction is dense, with about 20 hand traps, Dark Hole, Lightning Storm, Solemn Judgment and Harpie's Feather Duster, which earns the end-board and going-second scores. Floor and median output are not measured (no combos supplied), so they are text-only estimates and kept near the middle. The deck is Illegal (3 copies of Ash Blossom and 3 of Herald of Orange Light), so the Final score is capped low and treated as structural only. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: Illegal cap applied: No-meta Final = 0.80*Structural + 0.20*TournamentReliability = 0.80*55 + 0.20*45 = 53; modifiers -18 would clamp to -12 (see modifiers), giving 41, then the Illegal cap holds it at 35 (structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 package (20 hand traps, 18 negation-text cards) with high going-second coverage
• Archetype core is almost always accessible (0.992 in opening hand)
• Layered end-board answers: Dark Hole, Lightning Storm, Harpie's Feather Duster, Solemn Judgment, Evenly Matched
• Strong high-ATK Fusion and Link finishers

Weaknesses

• Illegal list: 3 copies of Ash Blossom and 3 of Herald of Orange Light exceed copy limits
• No Side Deck, so no post-side adaptation
• Low archetype purity (43.1%): many off-archetype hand traps and staples compete for slots
• Many hand traps are dead when going first

Critical choke points

• Melodious Fusion and Link starters: one-card starters with 2 to 3 copies each, so an early hand trap can stop the whole line
• The Illegal copy count makes the list non-tournament-legal until fixed

Recommended changes

Evidence & confidence

• Verified: Main 57 / Extra 15 / Side 0 size and copy-limit violations (Ash Blossom 3/2, Herald of Orange Light 3/1); Card stats and text from the resolved card list; Archetype core copies 34 and usage stat presence
• Inferred: Opening-hand probabilities for the core and starter groups; Going-first and going-second plan read from card text; Recovery and interaction density from text hints
• Provisional: Meta power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck, so post-side adaptability is unmeasured
