Melodious Deck #771028 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Melodious Fusion and Link pressure: Bacha, Schuberta and Flowering Etoile from the Extra Deck, with Melodious searchers and Special Summon enablers putting boards on the field (Inferred from card text; no combos recorded).; Hand-trap and tech-driven interaction (Ash Blossom, Ghost Belle, Ghost Ogre, Red Reboot, Infinite Impermanence) that trades for the opponent's engine, then rebuilds through Melodious recursion (Inferred).
• Turn 1 (going first): Open with a Melodious starter (Canon, Sonata, Refrain or Couplet) plus 1st Movement Solo, then Fusion or Link Summon into a Melodious boss while holding hand traps for the opponent's first response (Inferred).
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre or Infinite Impermanence to stop the opponent's first activated line, then convert the next Melodious summon into a Fusion boss (Inferred).
• Recovery: Recover through Soprano, Shopina and Couplet searches, Melodious Concerto recursion from the GY, and Ostinato, which Fusion Summons from the Extra Deck (Inferred from card text).
• After siding: Not evaluable: the deck has no Side Deck cards (Side Deck size 0), so no post-side plan is supplied.

Why it scores here

The deck reliably opens its Melodious core: 26 Melodious-named copies give a hypergeometric P(no core card in a 5-card opening hand) of about 0.034, so an engine starter is usually present (Inferred). Its interaction is dense, with 17 hand traps, 15 negation-text cards and 14 removal-text cards, so the system can answer an early opposing line in several ways (Inferred). The main cost is efficiency: only 51.4% of the exact-name archetype copies are Melodious, 23 tech slots are included, and the 20 generic cards dilute the engine. Floor and median output are unknown, since no combos or tournament records exist, so the score rests on text and structure only. The score is capped because the list is illegal, with Triple Tactics Talent run 2 times against a Forbidden status. Popularity and archetype usage were not credited, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: No-meta formula: 0.80*Structural(52) + 0.20*TournamentReliability(45) = 50.6; modifiers -12 gives 38.6; the Illegal cap (theoretical, structural-only) sets the final score to 25

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Core engine accessibility: P(no Melodious card in 5-card opening hand) ~ 0.034 (Inferred)
• Dense interaction: 17 hand traps and 15 negation-text cards (Verified count, Inferred effect)
• Full Extra Deck: 7 Fusion and 8 Link monsters with strong ATK bosses (Verified)

Weaknesses

• Illegal list: Triple Tactics Talent (Forbidden) run 2 times (Verified)
• Low main-deck efficiency: 51.4% exact-name purity and 23 tech cards (Verified count)
• No side deck, so no post-side adaptability (Verified)
• No recorded boards, so the combo floor and median are unknown (Verified gap)

Critical choke points

• Triple Tactics Talent is Forbidden, so the list cannot be played as built (Verified)
• Opening-hand dead draws from hand traps and tech cards whose conditions may not be met (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal list: Triple Tactics Talent is Forbidden and run 2 times (legal copies 0); Main 55, Extra 15, Side 0 are within OCG size rules; Extra Deck is 7 Fusion and 8 Link monsters; Copy histogram: 11 singles, 10 doubles, 8 triples; Core cards are Limited or Semi-Limited but within the legal copy counts
• Inferred: P(no Melodious card in 5-card hand) = 0.034 gives high engine access; Hand traps and negation text give dense interaction; Floor and median are uncertain without recorded boards
• Provisional: Meta power is provisional; no dated metagame sample
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match records are absent No win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) Meta Power is provisional without a dated metagame sample Deck title is null No side deck supplied (Side Deck size 0) Inconsistent usage flags: Flowering Etoile, Schuberta, Herald of Mirage Lights and S:P Little Knight appear in the Extra Deck card list but usage statistics marks in this deck false, so core-card presence (76.5) is understated
