Main 40 / Extra 15 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Fusion and Link pressure: Schuberta, Bacha, Flowering Etoile and Bloom Diva backed by Perfectron and Underworld Goddess as high-ATK finishers (Inferred from card text and ATK values); Interaction-led attrition: hand traps and negations strip the opponent's engine before the Melodious board takes over
- Turn 1 (going first): Open on Ostinato or 1st Movement Solo (no monsters on field), Fusion or Special Summon a Melodious monster, and keep Ash Blossom, Droll & Lock Bird or Maxx "C" up for the opponent's first summon or search (Inferred)
- Turn 2 (going second): Hold a hand trap (13 hand-trap-tagged copies; ~92% to have one in a 6-card hand) to answer the opponent's first set-up, then rebuild the Melodious board with Sonata, Soprano or Couplet (Inferred)
- Recovery: Recover Melodious monsters from the GY with Soprano and Shopina, and re-run Refrain/Couplet pendulum or Ostinato Fusion from the Deck (Inferred from card text)
- After siding: No side deck is registered (0 of 15 allowed), so there is no post-side plan; the deck cannot adapt between games of a best-of-3 (verified from legality)
Why it scores here
The deck opens a functional plan reliably: Ostinato or 1st Movement Solo (6 copies) gives about a 58% chance of a no-monster start in a 5-card opening hand, and a broader set of 17 Melodious starter and extender copies gives about a 95% chance of at least one live starter (Inferred, hypergeometric). Its interaction density is the strongest part of the system: 13 hand-trap-tagged cards and 12 removal-text cards produce a ~92% chance of at least one hand trap in a going-second 6-card hand, which is why D7 and D8 score high. Conversion and floor are not observed: there are no recorded boards, so the ceiling (D3) and median (D4) are text-only inferences and the median is scored conservatively. The deck loses points for having no side deck (D12 = 15), for a Limited-heavy list that exposes several key cards to a single-copy restriction, and for a Ostinato-versus-monster-dependent engine conflict. Archetype popularity (the 80-100% usage on Refrain, Ostinato and Ash) was not credited as power, and card scores were not averaged; the score comes from consistency, interaction and resilience measured on the system.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 70 | P(>=1 of Ostinato/1st Movement Solo in 5-card hand) ~0.58; P(>=1 of 17 Melodious starter/extender copies) ~0.95 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | 13 hand-trap cards and conflicting no-monster vs Melodious-on-field starters raise dead-card risk; no side to mitigate (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | Fusion/Link ceiling from Schuberta, Bacha, Flowering Etoile, Perfectron, Underworld Goddess; no recorded boards (Inferred from text) |
| D4 | Combo Floor & Median Output | 48 | combos_evidence is empty (total_combos 0); median output cannot be observed (Inferred, conservative) |
| D5 | Interruption Resilience & Route Redundancy | 72 | 6 starters, Soprano/Shopina GY recursion, and 13 hand traps give multiple independent lines (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 70 | Couplet search, Soprano/Shopina recovery, Pot of Prosperity and Melodious Concerto recursion (Inferred from text) |
| D7 | End-Board & Interaction Quality | 78 | Infinite Impermanence, Dominus Purge, Ash Blossom, Droll, Maxx C, Veiler, Ghost Ogre, Crossout, Nibiru, Perfectron mass-destroy (Inferred from text) |
| D8 | Going-Second & Board-Breaking Power | 75 | Going-second P(>=1 hand trap in 6 cards) ~0.92; Nibiru, Perfectron and Underworld Goddess answer a stable board (Inferred) |
| D9 | Offensive Pressure & Closing Power | 72 | Closing ATKs: Perfectron 5000, Underworld Goddess 3000, Nibiru 3000, Bacha 2500, Schuberta 2400 (Verified stat, Inferred closing) |
| D10 | Main Deck Efficiency & Flexibility | 62 | 40 main (min 40), 22 distinct cards, 12 singles; hand-trap and tech overlap dilutes the engine (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 64 | Extra Deck full at 15 with 9 Fusion and 6 Link; Schuberta/Bacha 3-copy anchors; Perfectron is single-copy Limited (Verified from composition) |
| D12 | Side Deck Adaptability | 15 | No side deck (side_count 0); no post-side plan at all (Verified; structural only) |
| D13 | Matchup Coverage & Format Fit | 55 | Archetype core usage 60% in the 25-row stat list; no dated metagame sample, no tournament link (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Pendulum, Fusion and Link timing plus hand-trap windows raise decision load; combo count unknown (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 64, Going First ≈ 68, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: banlist_exposure (-2); no_side_deck (-3); engine_conflicts (-2); interaction_redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*64 + 0.20*56 - 5 = 57
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.58 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Layered hand-trap and negation suite (Ash x2, Droll, Maxx C, Veiler, Ghost Ogre, Infinite Impermanence, Dominus Purge)
- Multiple independent starters (Ostinato, 1st Movement Solo, Sonata, Soprano, Couplet, Refrain) with GY recursion
- Strong closing ATKs in the Extra Deck (Perfectron 5000, Underworld Goddess 3000, Nibiru 3000)
Weaknesses
- No side deck; no post-side adaptation for best-of-3
- Ostinato and 1st Movement Solo conflict with monster-dependent payoffs
- Several single-copy Limited cards form a fragile restriction exposure
Critical choke points
- Ostinato / 1st Movement Solo as the only no-monster starter pair (6 copies, ~58% in opening hand)
- Maxx C and Droll as the single-card answers to opponent search and summons (Inferred)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 0 cards (no side deck registered) | A full 15-card side deck with extra answers to the opponent's main engines | The deck has zero side slots, so every best-of-3 game repeats the same plan; a side is the largest structural gap (Verified) |
| 2 | 1x Melodious Illusion | 1x additional Melodious monster or starter | Melodious Illusion is a one-copy protection trap with no interaction text; a monster starter adds to the 17-copy starter pool and reduces the no-monster dependency (Inferred) |
Evidence & confidence
- Verified: Legal OCG: 40 main, 15 extra, 0 side; all restricted cards at legal copy counts; Copy histogram 1:12, 2:2, 3:8 and Extra Deck 9 Fusion / 6 Link; Usage stats: Refrain, Ostinato 100% core; Ash 80%
- Inferred: P(>=1 starter) and P(>=1 hand trap) from hypergeometric draw table; Structural ceiling and interaction quality from card text; Engine conflict between no-monster starters and monster-dependent payoffs
- Provisional: Meta Power (null); Matchup coverage (D13)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is Provisional without a dated metagame sample No side deck: post-side plan cannot be evaluated
