Mulcharmy Deck #696148 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro summon Level 2 tuners to loop board presence and grind advantage via Yummy recursion and Radiant Typhoon recursion; convert to lethal via ATK boosting or board flood; Activate quick-play Spells to special summon boss monsters (Varuroon/Fonix Level 9) for disruption and removal; control opponent's board state
• Turn 1 (going first): Open with Yummy or Radiant Typhoon engine starter; Normal Summon a Level 1 Yummy or search MST; Link Summon Yummy★Snatchy for Field Spell placement; Synchro into Level 2 tuners (Cupsy Way, Lollipo Way) to search and extend; establish a board with 1–2 negations via Herald or Lollipo Way effects and grind resources
• Turn 2 (going second): Hold hand traps (Ash, Ghost Belle) and quick removal tools (MST, Radiant Typhoon removal); use Yummyusment★Acroquey to destroy opponent board on Synchro; leverage going-second Synchro summons and Mulcharmy draw effects to rebuild hand
• Recovery: Yummy monsters recursion via Marshmao and Cupsy effects; Radiant Typhoon GY recovery via Manifestation and Chant; Level 2 tuners as starters for follow-up Synchro lines; Mulcharmy draw engines activate on opponent summons to maintain card economy
• After siding: No side deck available in Master Duel; deck must rely on main deck flexibility and hand trap density

Why it scores here

This Mulcharmy deck opens a functional Synchro engine backed by dual Yummy and Radiant Typhoon sub-cores, achieving moderate consistency (P ≥1 Yummy/Radiant Typhoon starter ≈ 0.81). The best line produces a board with 1–2 negations and recursion value via Level 2 tuners, but median output is narrower—Synchro summons are limited to 2–3 per turn and require careful material sequencing. Recovery hinges on GY recursion and opponent summon triggers (Mulcharmy draw effects), making the deck vulnerable to specific disruptions like Maxx C or Deck-locking effects. The main deck efficiently uses 23 distinct cards to avoid bricks, but the Extra Deck lacks redundancy in key lines (only one Herald of the Arc Light at Limited cap, limited Level 9 bosses). A 0-card side deck in Master Duel removes adaptive post-side power. Popularity and archetype statistics did not influence scoring; the deck's power is driven by engine consistency, modest ceiling output, and grind resilience in a trade-off against fragile T1 boards and weak board-breaker access.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 60, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: No side deck (Master Duel format) (0). Final formula: 0.80·Structural (57) + 0.20·TournamentReliability (56) + 0 modifiers = Final 57 → 58 (rounded)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · key two-card combo ≈ — · full-brick estimate ≈ 0.19 (all Inferred)
• Combo output: best PowerIndex 68, median 58, board-per-starter 2.1
• Turn order: — going-first lines vs — going-second lines

Strengths

• Dual sub-core (Yummy + Radiant Typhoon) provides routing redundancy and consistent opening hands
• Level 2 Synchro tuners (Cupsy/Lollipo Way) create intrinsic recursion loops and searcher access
• Mulcharmy Fuwalos/Purulia conditional draw engines provide grind resilience when opponent controls summons
• 7 hand traps (Ash, Ghost Belle, Droll) support going-second disruption and hand-trap chains
• Efficient main deck with 13 searchers and 23 distinct cards minimizes dead draws
• Field Spell placement (Yummy Snatchy effect) enables repeated ATK boosting and Synchro material access
• Herald of the Arc Light (Limited 1×) provides single negation / banish layer

Weaknesses

• Combo ceiling capped by Extra Deck constraints (single Herald Limited, limited Level 9 bosses, only 2 Synchro tuner copies per type) — cannot build multi-negation boards
• Going-first boards lack aggressive interruption (passive negation + removal, not active disruption)
• Starter dependency on GY recursion and opponent summon triggers makes the deck vulnerable to Maxx C, decking, and board-locking effects
• Link-1 requirement for Yummy activation creates choke point if Yummy Snatchy is removed or Synchro lines are disrupted early
• No board breaker access or out to large multi-negation boards in main deck; going-second tooling limited
• ATK boosting capped (~500 per LIGHT Beast), limiting offensive ceiling and closing speed
• Conflicting Normal Summon options (multiple Level 1 Yummys) increase hand friction and brick risk
• No side deck in Master Duel format; cannot adapt post-side to counter-decks or tuned matchups

Critical choke points

• Yummy Snatchy Link Summon: if negated or removed before setting a Field Spell, the T1 line collapses into a weak board with minimal recursion access
• Level 2 tuner Synchro summon disruption: Ash on Cupsy Way search or MST on Radiant Typhoon quest removes key extenders; deck pivots to single-line grind
• Mulcharmy draw engine activation: if opponent does not summon (board established T1), draw engines are dead; deck becomes resource-starved without external card advantage
• GY banishing effects (banish recursion targets): Herald/Lollipo Way recovery lines depend on GY being live; Macro Cosmos, D.D. Crow, or banish-lock disruption cripples recursion
• MST / Radiant Typhoon setup condition: Radiant Typhoon special summon requires 'MST in GY OR opponent no S/T' — if neither condition is met T1, core routing collapses

Copy histogram: 10×1-copy, 9×2-copy, 4×3-copy. Extra-Deck breakdown: 6 Link, 7 Synchro, 2 Xyz. (Verified: composition + cards arrays); Text role hints: Searcher text identified on 13 cards (Cupsy Way, Lollipo Way, Cooky Way, Radiant Typhoon Eldam, Radiant Typhoon Swen, Radiant Typhoon Chant, Radiant Typhoon Manifestation, Yummy Surprise, Yummyusment★Acroquey, Radiant Typhoon Varuroon Marine Eidolon, Radiant Typhoon Mandate, Radiant Typhoon Vision, Cupsy Yummy). Hand-trap text on Ash (3×), Ghost Belle (2×), Droll (2×). (Verified: card descriptions + role hints fields); Archetype usage stats: 8 stat rows supplied; Mulcharmy Fuwalos/Purulia core (71% inclusion), ZEUS missing (71%), Maxx C missing (57%), HFD missing (57%). (Verified: usage statistics.core cards array)
• Observed: Archetype purity 7.3% exact-name (only 4 exact 'Mulcharmy' cards run) reflects sub-core design; archetype_spread shows Yummy 20, Radiant Typhoon 15, generic 15, Mulcharmy 4. (Observed: composition.archetype purity + archetype_spread); Searcher density: 13 searchers across main deck reduces dead-draw frequency vs a typical Mulcharmy list missing Maxx C / ZEUS slots.
• Inferred: Engine accessibility (D1): P(≥1 viable Yummy/Radiant Typhoon/MST starter in 5-card opening) ≈ 0.81 via hypergeometric bootstrap; Yummy condition (Link-1 or Level 2 Synchro required) adds dependency but is satsifiable from deck searchers. (Inferred: probabilities.per_card_top + hypergeometric formula); Brick rate (D2): ~19% full brick proxy estimated from 10 singletons + conflicting Normal Summon conditions (Marshmao 'no monsters or all LIGHT Beast' conflicts with Lollipo/Cooky/Cupsy setup). (Inferred: composition copy histogram + card text logic); Combo ceiling (D3): Best line ≈ 68 PowerIndex. Yummy→Link→2 Level 2 tuners + Herald negate + GY special inferred as moderate 3-effect board from card text (no combo evidence supplied). (Inferred: cards descriptions + role hints + combo mechanics logic); Combo median (D4): Median ≈ 58 PowerIndex. Typical line = 1 Synchro with search + modest removal, +1 card economy. (Inferred: starter diversity + resource signature logic); Interruption resilience (D5): 2 independent lines (Yummy via Link, Radiant Typhoon via MST in GY). GY recursion via Marshmao/Cupsy enables pivot if one line disrupted. Moderate rerouting. (Inferred: card text + route redundancy analysis); Resource economy (D6): Mulcharmy draw engines (Fuwalos on opponent special from Deck/Extra; Purulia on opponent summon from hand) activate conditionally. Estimated +2 card economy over 2 turns with active triggers. (Inferred: card descriptions + resource-signature analysis); Interaction quality (D7): 1–2 negations (Herald 1×, Lollipo Way conditional). Interaction density ≈ 2.3. Passive board (no aggressive disruption floodgates). (Inferred: end-board text analysis + card roles); Going-second power (D8): 7 hand traps + MST + Cooky removal provide moderate going-second coverage. Yummyusment★Acroquey board-wipe conditional (requires Synchro). Cannot answer large multi-negation boards reliably. (Inferred: hand-trap density + card text coverage); Offensive power (D9): Fonix 3000 ATK + Yummy Field boost max ~500 = ~3500–4000 close power. No piercing, no OTK. Finishing power below average. (Inferred: ATK stats + card text + grind closers); Main Deck efficiency (D10): 23 distinct cards, shallow copy distribution (max 3), 13 searchers, 7 hand traps, 1 trap card. Efficiency score ≈ 64 (compact, coherent, flexible). (Inferred: composition analysis + role distribution); Extra Deck efficiency (D11): 15 slots, 8 mandatory summons (Yummy Snatchy 2×, Level 2 tuners 5×, Herald 1×), 7 flex. Coverage moderate. Efficiency score ≈ 63. (Inferred: Extra Deck card roles + usage frequency); Side Deck (D12): Master Duel format has 0-card side deck. Dimension structurally absent. Score = 0. (Inferred: Master Duel format rule); Matchup fit (D13): Archetype meta-share unknown; no dated metagame sample. Archetype core inclusion 25% (2/8 core cards present). Deck deviates from meta-standard. Matchup fit provisional. (Inferred/Provisional: archetype stats + core inclusion % + format-unknown flag); Pilotability (D14): Combo complexity moderate (Synchro bootstrap, ~6–8 decisions per turn). Error tolerance low for GY sequencing. Score ≈ 54. (Inferred: combo step analysis + decision-point count)
• Provisional: Meta Power (not computed): archetype meta-share in Master Duel unknown; no dated metagame sample supplied. Meta Power = null per rubric. Final formula uses 0.80·Structural + 0.20·TournamentReliability.; Matchup-level win rates: not available in YGOVN for most decks. Matchup fit (D13) rated Provisional due to missing dated-meta context.
• Data gaps: No combo data supplied (total combos = 0, scored combos = 0). All combo analysis (ceiling, median, board-per-starter) is text-only inference from card descriptions and rules logic, labeled Inferred. No tournament link; no per-pilot match record or archetype meta-share data in the exact format environment. No win-rate telemetry exists in YGOVN for this deck (going-first/second brick rates, matchup-specific results, game-level outcomes) — these are Inferred or Unknown. Meta Power Provisional: no dated metagame sample supplied. Archetype core inclusion is 25% (2/8 core cards), suggesting deck deviates from meta-standard, but without a dated sample the matchup power cannot be calibrated.
