Solfachord Deck #698405 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±6 · Confidence: Medium)

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

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Pendulum-Synchro combo into Solfachord bosses with multi-layer negation and removal; Yummy grind engine with hand trap disruption and resource denial
• Turn 1 (going first): Open Solfachord Primoa → Solfachord Happiness to set Pendulum Scales; Synchro summon Solfachord bosses (GranSolfachord Coolia or similar) to establish negation locks and board interaction
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Belle, Droll & Lock) to disrupt opponent setup; Forbidden Droplet for board break; Yummy monsters to apply pressure or enable recovery lines
• Recovery: Yummy Synchro monsters (Cupsy★Yummy Way, Cooky★Yummy Way) recover from disruption; Herald of the Arc Light banish loop and recursion from field spells; Link monsters enable second turns
• After siding: Unknown — no side deck supplied; core consistency remains; tech adjustments via hand-trap density and removal suite

Why it scores here

This Solfachord Yummy hybrid opens its Pendulum engine reliably (~90% chance of at least one core card T1) and converts into multi-negation boards via Synchro summoning, supported by strong hand-trap density (11 copies) and board-breaking spells. However, the median combo floor is modest due to high brick risk from conflicting engines (Mulcharmy, Sky Striker, and Yummy sub-engines compete for normal summon slots), reliance on Link-1 enablers for Yummy activation, and loss of key Extra-Deck monsters (I:P Masquerena, S:P Little Knight, GranSolfachord Coolia) that compress consistency. Going-second capability is real via Forbidden Droplet and hand traps, but offensive pressure is limited by low ATK values and heavy setup cost. The deck is legal and plays as intended, but construction gaps and lack of tournament data prevent a higher score.

Dimension scores

How the score was computed

Strategy profile: 85% Combo + 15% Toolbox. Structural ≈ 64, Going First ≈ 70, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Missing core Extra-Deck cards (-3); Multi-engine friction (-2); No side deck (-1). Final formula: 0.80·Structural + 0.20·TournamentReliability (Meta provisional; no dated metagame sample supplied)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex 75, median 60, board-per-starter 2
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Reliable Pendulum Scale setup with 6 Solfachord Pendulum monsters and dual-scale searcher (Solfachord Happiness 3x); ~90% T1 core access
• Multi-layer negation via Herald of the Arc Light (Limited, negates Spell/Trap), Solfachord Synchro effects (negate opponent effects in Pendulum Zones), and Forbidden Droplet effect negation
• Strong hand-trap density (11 copies) covering searches (Ash Blossom, Droll & Lock), graveyard access (Ghost Belle), and Synchro spawns (Nibiru, Infinite Impermanence)
• Yummy Synchro Tuners (Cupsy★Yummy Way, Cooky★Yummy Way) enable recovery loops and second turns via Link-1 enablers
• Archetype coherence on Solfachord core with natural Pendulum protection and searcher redundancy

Weaknesses

• Low offensive pressure: Solfachord and Yummy bosses have 0–2700 ATK with no piercing or direct damage; grind-focused rather than OTK-capable
• Multi-engine friction: Mulcharmy (4 copies requiring empty board), Yummy (requiring Link-1 or Synchro Level 2), and Sky Striker (1 copy, niche) compete for limited Main Phase actions and Normal Summons; increases brick rate
• Missing three 100% meta staple Extra-Deck cards (I:P Masquerena, S:P Little Knight, GranSolfachord Coolia); limits combo ceiling, consistency, and redundancy
• Synchro dependency: Most lines require successful Synchro summon; single choke point if Tuner or Synchro material is disrupted before resolution
• No side deck in Master Duel best-of-1: no post-game adaptation; cannot adjust for specific matchups
• Median combo floor modest (~60 Power Index) due to backup line scarcity; one interruption often leaves single boss or Link enabler, not resilient boards

Critical choke points

• Solfachord Primoa must resolve to set Pendulum Zones; negation before setup prevents entire turn architecture
• Link-1 enabler required for Yummy activation; if Yummy★Snatchy or similar is missing, recovery lines stall
• Herald of the Arc Light (Limited, 1 copy) critical negation tool; no backup negate synergy if used early or sent to GY
• Mulcharmy Fuwalos and Purulia require empty board T1 or their effects fail; conflicts with Solfachord setup in early game

Evidence & confidence

• Verified: Legality: Legal (43 Main, 15 Extra, 0 Side; all restricted cards within limits); Card text and frames resolved from preprocess.py; Banlist status per Master Duel (Called by the Grave Limited, Crossout Designator Limited, Herald of the Arc Light Limited, Maxx C Limited, Sky Striker Hornet Drones Limited, Droll & Lock Bird Semi-Limited); Archetype core composition: 9 Solfachord exact-name cards, 17 Yummy sub-archetype, 4 Mulcharmy; Usage statistics: 7 of 13 meta-standard core cards present (53.8% fidelity)
• Observed: Hand-trap density: 11 copies (Ash Blossom 3x, Ghost Belle 3x, Droll 2x, Infinite Impermanence 1x, Maxx C 1x, Nibiru 1x); Searcher card count: 12 copies with text hints (Solfachord Happiness, Solfachord Primoa, Cupsy★Yummy, Marshmao★Yummy, Herald of the Arc Light, etc.); Extra-Deck structure: 10 Links (mostly Yummy/utility), 5 Synchro (Yummy Tuner bosses + Herald + Martial Metal Marcher + Veiler placeholder)
• Inferred: Archetype core engine accessibility P(≥1 in hand 5) ≈ 0.8979 via hypergeometric from 15 core copies in 43-card main; Brick estimate ~10.2% (inverse of above; conflict-adjusted to ~12–14% due to Mulcharmy empty-board requirement); D1 Consistency ≈ 74: high core draw probability offset by multi-engine friction; D2 Brick Management ≈ 66: significant garnet risk from Mulcharmy and conflicting Normal Summon slots; D3 Combo Ceiling ≈ 71: Pendulum Scales + Synchro into Herald or Solfachord boss with 1–3 negations; D4 Combo Median ≈ 58: single boss + Link enabler without robust second line; D5 Interruption Resilience ≈ 62: Yummy Synchro recovery available but bottlenecked by Link-1 enabler and missing GranSolfachord Coolia; D6 Resource Economy ≈ 64: Solfachord searchers and Cupsy★Yummy Way provide float; Mulcharmy discard cost and engine friction net to mixed grind; D7 Endboard Interaction ≈ 68: Herald negation + Solfachord Synchro effect protections; missing GranSolfachord Coolia reduces ceiling; D8 Going-Second ≈ 65: hand-trap coverage and Forbidden Droplet strong; no native force-interaction or heavy board clear; D9 Offensive Closing ≈ 54: low ATK values and no piercing; chip damage via grind or attrition; D10 Main Deck Efficiency ≈ 61: 43 cards, 24 distinct, archetype purity 15.5%; multi-engine reduces coherence despite tight tech ratios; D11 Extra Deck Efficiency ≈ 67: strong Link variety for Yummy enablers and Synchro support; three missing 100%-inclusion cards limit ceiling; D14 Pilotability ≈ 55: moderate combo complexity with branching routes (Mulcharmy, Yummy, Solfachord paths); multiple decision points; Pendulum Scale placement requires precision
• Provisional: Meta Power: Null — no dated metagame sample supplied; archetype meta-share in Master Duel not quantified; Matchup favorability: Unknown without tournament data or pilot records; Post-side strategy: Best-of-1 Master Duel format; no side deck to evaluate (0/15 slots used)
• Data gaps: No combo boards parsed: best line, median power index, and board per starter are entirely inferred from card text and architecture, not observed from game logs No tournament link: archetype meta-share, pilot match records, and win-rate telemetry absent; Meta Power remains Provisional No side deck supplied: Master Duel best-of-1 format; 0/15 side slots filled; D12 Side Deck Adaptability scored 0 per schema (not a weakness, a format constraint) No dated metagame context: cannot compute matchup coverage or format-speed alignment; D13 Matchup Format Fit is Provisional No hand-brick / full-brick / combo-success telemetry: consistency and floor estimates rely on hypergeometric probabilities and card-text inference, not historical game data No per-pilot error-rate or piloting data: D14 Pilotability is step-count and complexity inference only
