Sunseed Deck #53506 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 0/100 (±0 · Confidence: Low)

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

Legality

Main 44 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Plant Link/Xyz combo into interaction layering; Grindy Plant recursion and field control via Sunavalon/Rika engines
• Turn 1 (going first): Bootstrap Rikka/Sunseed starters into Sunavalon Link setup; establish negation and recursion via Rikka searchers; set traps for going-second disruption
• Turn 2 (going second): Use hand traps (Ash, Maxx C, Impermanence) to slow opponent combo; leverage Unexpected Dai and One for One to build Plant board; pivot into removal and board-breaker lines
• Recovery: Rikka recursion (Princess negation, Petal GY loop) and Xyz tribute effects (Strenna detach, Kanzashi tribute recovery) to rebuild after disruption
• After siding: No side deck supplied (0 cards); evaluation theoretical only

Why it scores here

This deck is illegal in Master Duel format (Extra Deck 18 > 15, Maxx C 2 > 1, Called by the Grave 2 > 1), so it receives a structural-only evaluation below20 to reflect its unplayable status. The core engine—Sunseed Genius Loci, Rikka Petal, Rikka Princess, and searchers—has reasonable draw odds (~87% to see a starter in hand) and can assemble a Plant Link/Xyz board with layered recursion and modest negation. However, the deck deviates significantly from published Sunseed cores (only 28% core-card overlap), substituting key Sunavalon pieces (Dryas, Daphne, Melias, Healer, Thrasher) with hand traps and generic tech, which fragmentizes the engine. Without combos parsed, the ceiling and floor remain inferred from card text alone—modest Xyz boards and Link chains are achievable, but starter diversity is low and resource efficiency is unclear. A zero side deck precludes best-of-3 adaptation. The legal violations make this deck unplayable in any rated context.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 48, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegality penalty (-100); No side deck (-5); Core deviation (-8). Final formula: Illegal deck — score capped at 0; structural analysis provided for reference only

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Rikka engine core offers consistent tutoring and Quick-Effect negation via Princess
• Hand-trap load (9 copies) provides robust going-second interaction and disruption
• Xyz tribute effects (Strenna, Kanzashi) enable resource recycling and recovery after disruption
• Petal GY loop and Rikka recursion support multi-turn grinds and rebooting
• Sunavalon Link starters (if assembled) provide non-targeted board immunity for chained boses

Weaknesses

• Only 28% core-card overlap with Sunseed archetype standard; key Sunavalon pieces (Dryas, Melias, Thrasher, Healer) missing, fragmentizing the engine
• Illegal in Master Duel: Extra Deck 18 > 15, Maxx C 2 > 1, Called by the Grave 2 > 1
• Hand-trap heavy (9 copies) creates redundancy and brick risk; hand quality inconsistent
• No side deck (0 cards) precludes best-of-3 adaptation; cannot pivot post-game 1
• Extra Deck bloated (18 slots): redundant Sunavalon Link copies (3× Dryas, 2× Melias) waste space; mandatory Level 9 Xyz (Hyperyton, Alsei, Teardrop) are dead without specific Level stacks
• Low offensive ceiling; Xyz boses max ~2800 ATK without piercing; grindy closures rely on repetitive loops rather than explosive pressure
• Missing key Sunvine enablers (Thrasher, Healer) weakens the Link turn-2 board and recovery pivots

Critical choke points

• Deck is illegal and unplayable in Master Duel format; cannot be legally registered
• Missing core Sunavalon/Sunvine pieces (Dryas, Daphne, Melias, Thrasher, Healer) means Sunavalon Link combos are severely constrained or impossible
• Maxx C and Called by the Grave over copy limits reduce consistency and interaction reliability in adjusted form
• No side deck leaves no post-game1 strategy in best-of-3; fixed main deck must address all matchups simultaneously
• Extra Deck over-size (18) forces difficult cuts; redundant Sunavalon slots (3× Dryas, 2× Melias) signal poor Extra Deck prioritization
• High hand-trap density (9 copies) dilutes combo starters and creates draw clutter; opening hands often lack a coherent game plan

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Extra Deck 18 > 15, Maxx C 2 > 1, Called by the Grave 2 > 1) — Master Duel format rules; Main Deck size: 44 cards (legal range 40–60) — within format limit but unbalanced; Card text: all 36 distinct cards resolved and excerpt-verified; Archetype core: Sunseed (4 copies), Rikka (19 copies), Sunavalon (5 copies) — composition verified from card objects; Usage statistics: 7 of 25 core cards present (28% overlap); 18 missing core cards identified
• Observed: Archetype core draw probability P(≥1 starter in hand 5) ≈ 87% from hypergeometric model on 14 core copies; Hand-trap density 9 copies, searcher density 8 copies, interaction density 8 + 12 negation text + 9 removal text cards
• Inferred: Combo ceiling: Rikka Princess → Glamour search → Unexpected Dai → Sunavalon Dryas Link1 (if present; not in deck) → Rikka Strenna Xyz with negation + recursion; ~2–3 sumons, modest board (text-only, no combos parsed); Combo floor: One starter → one Unexpected Dai or Rikka Petal → one Xyz or Link with float; ~1–2 summons; Brick rate: ~13% full brick (no starter); hand-trap heavy load increases variance; Going-first board: 1–2 interaction pieces (Princess negate, one Xyz); no recursion loop visible without Sunavalon Melias; Going-second plan: hand traps into Unexpected Dai board; modest board-breaker potential; Engine coherence: Low; 28% core overlap + 16-slot tech splice fragment synergy; Sunavalon lines incomplete (missing Dryas, Melias, Thrasher, Healer); Extra Deck efficiency: Bloated at 18 slots; redundant Sunavalon copies (3× Dryas, 2× Melias) and mandatory high-Level Xyz waste space; Pilotability: Moderate; Rikka tutoring chains are2–3 steps; hand-trap heavy; no known piloting error tolerance
• Provisional: Meta Power: null (no dated metagame sample supplied; archetype meta-share unknown for Master Duel; Sunseed is niche); Matchup coverage: Inferred poor; no side deck + tech splice + incomplete Sunavalon engine suggests vulnerability to known meta decks; Tournament reliability: Inferred low (high brick variance from hand-trap density, no side deck, engine fragmentation)
• Data gaps: Deck is illegal in Master Duel: unplayable; score capped at 0 for structural-only reference No combos supplied — combo floor, median, ceiling are text-only inferences, not measured board data No tournament link or metagame sample — Meta Power is null/provisional; format fit unknown No win-rate telemetry (brick rate, starter consistency, per-matchup outcomes, going-first/second split) — all consistency claims are Inferred from hypergeometric model No side deck (0 cards) — best-of-3 adaptability cannot be evaluated Missing core Sunavalon/Sunvine pieces (18 of 25 core cards absent) — actual engine performance vs. published Sunseed lists is unknown High hand-trap load (9 copies) may inflate brick risk beyond model's hypergeometric estimate — empirical frequency unknown
