Solfachord Deck #762136 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: master-duel

Legality

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

Identity & game plan

• Win condition: Yummy monster chain through Link-1 and Level-2 Synchro enablers into Link and Synchro bosses (Coolia 2700 ATK, Fancy Ball 2400 ATK, Musecia 1900 ATK); Hand-trap-supported grind: Solfachord Happiness and Cupsy/Acroquey searches convert card advantage into a board
• Turn 1 (going first): Open a Yummy monster that can be hand-summoned only after a Link-1 or Level-2 Synchro is on the field, so the T1 starter is often a Normal Summon of Lollipo or Cooky plus a hand trap held up
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Infinite Impermanence, Droll and Maxx C to answer the opponent's first board, then rebuild through Mulcharmy draws and Happiness
• Recovery: Solfachord Happiness (up to 3 copies) and Mulcharmy Fuwalos recover cards from the Deck, and Yummy Surprise can re-summon a Yummy monster from the GY
• After siding: Not available: 0 side deck cards, so there is no post-side plan (Inferred)

Why it scores here

The list reliably opens interaction: with 12 hand traps and about 17 negation-text cards, a going-second hand holds at least one hand trap about 90% of the time (Inferred). Its engine is a Yummy chain that needs a Link-1 or Level-2 Synchro on the field before the hand-summoned Yummy monsters work, so consistency depends on the Extra Deck holding those enablers, and the probability of at least one Yummy monster in a 5-card opening hand is about 74% (Inferred, hypergeometric). Conversion and median output cannot be verified because no recorded boards exist, so the ceiling rests on the card text and the floor is not measured. The deck keeps pressure through Coolia, Fancy Ball and Musecia and is protected by Dominus Purge and Herald, but the 14.5 percent exact-name purity and mixed Yummy, Solfachord, Dominus and Mulcharmy engines lower its structural score. The score reflects consistency, median output and interaction at the system level, not popularity and not an average of card scores. Meta Power is provisional because no dated metagame sample exists, and the zero-card side deck leaves no post-side plan.

Dimension scores

How the score was computed

Strategy profile: 0.70 Midrange / 0.30 Combo. Structural ≈ 59.3, Going First ≈ 56, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine_conflicts_and_low_purity (-3); no_side_deck (-2); banlist_exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*59.3 + 0.20*52 - 6 = 51.8, rounded to 52

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.74 · 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

• Hand-trap density (12) gives a high going-second answer rate
• Layered negation and destruction (Dominus Purge, Herald, Solfegia, Acroquey)
• Recovery through Happiness, Mulcharmy and Yummy Surprise
• Legal list with all Limited and Semi-Limited copies within limit

Weaknesses

• Mixed engines: 14.5 percent exact-name purity, with Yummy dominant but the label reads Solfachord
• Yummy monsters need a Link-1 or Level-2 Synchro on field, a circular dependency on the Extra Deck
• No side deck, so no post-side adaptation
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Link-1 or Level-2 Synchro enabler on field before Yummy monsters can be hand-summoned
• Limited cards (Crossout Designator, Cupsy Yummy, Maxx C, Herald) at one copy each

Recommended changes

Evidence & confidence

• Verified: Legal status under master-duel size rules (40 main, 15 extra, 0 side) and copy limits; Banlist status of Limited and Semi-Limited cards, all within copy limits; Card text of all resolved cards; Archetype spread: Yummy 17, Solfachord 8, Dominus 5, Mulcharmy 3
• Observed: Usage statistics: 80 percent inclusion for Yummy Way and Solfachord core cards, with 13 of 25 core cards present (52 percent)
• Inferred: Hypergeometric P(>=1 Yummy monster in 5) ~0.74; Hand-trap P(>=1 in 6 going second) 0.90 from evidence; Interaction and Yummy chain strength from card text; Structural and final scores from the 14-dimension rubric
• Provisional: Meta Power (no dated metagame sample); D13 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 match record absent no win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power provisional without a dated metagame sample deck title is null
