Melodious Deck #767793 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (The First Darklord, Darklord Eveningstar, Darklord Morningstar, Melodious Fusions) and Link beaters, reached through Darklord and Melodious Fusion/Pendulum lines, with Forbidden Crown and Super Polymerization-style plays as tech; Chip damage from Fairy/Herald Link monsters and Mediclius end-board negation
• Turn 1 (going first): Open a Darklord starter (Gulgolet, Djehuty, Ostinato) or Refrain/Couplet Pendulum line, extend with Darklord searchers (Banishment, Contact, Gulgolet) toward a Fusion or Link boss, holding Ash/Herald/Ghost Belle as interaction
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Belle, Herald of Orange Light, Droll & Lock Bird, Evenly Matched) to disrupt the opponent's first engine, then rebuild the board through Darklord recursion and Fusion
• Recovery: Recover from GY through Darklord Contact, Eveningstar Set effects and Darklord Rebellion/Fallen Angel in Darkness, plus Mulcharmy and Ixchel draw effects
• After siding: No side deck is registered, so no post-side plan exists in this list

Why it scores here

The deck is scored as a system: its opening odds for the Darklord and Melodious starter cores are high (about 0.92 for at least one core card in a 5-card hand), and it has enough searchers and hand traps to keep a plan alive through one interruption. Its interaction is broad, with about 19 negation-text cards and 13 hand traps, which gives it real end-board control on both turns. Its ceiling and median output cannot be measured because no combos were supplied, so conversion scores rest on card text and are Inferred. The list is also a loose mix of Darklord, Melodious, Herald and Forbidden cards with only 15.7 percent exact-archetype purity, which costs consistency and pilotability. Popularity and archetype share earned no points, and card scores were not averaged. The list is Illegal under OCG copy limits on three cards, so the final score is capped low and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-5); no Side Deck (-3); low_exact_archetype_purity (-1). Final formula: Illegal cap applied. Normal formula: 0.80*Structural(49) + 0.20*TournamentReliability(40) + modifiers(-9) = 38; capped to 25 because three cards exceed OCG copy limits. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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 archetype cards are reliably accessible in opening hands (about 0.92)
• Dense interaction: 13 hand traps and 19 negation-text cards
• Multiple Extra Deck routes (9 Fusion, 6 Link) and strong bosses
• Searcher and draw density (15 searcher-text cards, plus Mulcharmy and Ixchel draws)

Weaknesses

• Illegal under OCG copy limits: Ash Blossom and Super Polymerization each at 3 copies (limit 2), Herald of Orange Light at 3 (limit 1)
• Low exact-archetype purity (15.7 percent) and many off-archetype cards
• No side deck
• No combo evidence, so output and conversion cannot be verified
• Many singletons and tech slots raise brick and decision risk

Critical choke points

• Herald of Orange Light and the Limited/Semi-Limited hand traps must be cut to legal copies before the deck can be played in OCG
• Opening-hand dependence on Darklord starters with no alternate route if they are disrupted
• Dependence on the Extra Deck Fusion and Link bosses to close games

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 within OCG size rules; Three copy-limit violations (Ash Blossom, Herald of Orange Light, Super Polymerization); Card stats and text for the listed cards; Archetype core share 100 percent for Refrain and Ostinato in usage stats
• Inferred: Opening-hand consistency from hypergeometric draw odds; Brick and interaction quality from card text and composition; Going-first and going-second estimates
• Provisional: Meta and format fit (D13) because no dated metagame sample exists
• 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: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered
