Sunseed Deck #65111 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Medium)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Establish a Plant Link board with negation and recursion; Grind value through repeated summoning and search loops
• Turn 1 (going first): Link Summon Sunavalon bosses (Melias, Dryatrentiay) for negation and recursion; set Rikka Trap coverage
• Turn 2 (going second): Use Sunvine Sowing and Unexpected Dai to establish board without relying on Extra Deck; break opponent board and pivot to offense
• Recovery: Leverage Rikka Petal, Rose Lover, and Spore recursion from GY; use Rikka Glamour to search and rebuild
• After siding: Cannot evaluate: no Side Deck supplied; deck is Master Duel format with 0 side cards

Why it scores here

This Sunseed-Rikka hybrid is mechanically coherent—leveraging Rikka searchers, Sunvine Link summoning, and Lonefire Blossom loops to generate board presence and GY setup. However, the deck is Illegal in Master Duel format, running 3 Maxx "C", 2 That Grass Looks Greener, and 2 Called by the Grave when format limits allow only 1 copy of each. Structurally, it suffers from a 60-card size and heavy banlist violations that would collapse consistency if played legitimately. The combo ceiling is modest (2–3 Link monsters, modest interaction) and the median output assumes interrupted lines, creating a fragile median-to-ceiling gap. Core engine probability P(≥1 Rikka starter in opening 5) ≈0.75, but the deck misses critical cards like Sunavalon Dryas (0 copies vs. standard 2–3) and the Blessed Winds/Humid Winds field spell core, leaving it 28% of archetype standard. GY recursion and Tributing engines provide recovery pathways but are not redundant enough to survive realistic disruption. The deck's popularity does not drive the score—illegality and engine deviation do.

Dimension scores

How the score was computed

Strategy profile: 0.70 Combo + 0.30 Midrange. Structural ≈ 52, Going First ≈ 58, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Illegality penalty (banlist violations) (-16); Archetype core deviation (-8); 60-card size penalty (-4). Final formula: Illegal deck: Structural capped at 52 for missing archetype core and engine deviation; Final = 0.35*Structural + 0.20*TournamentReliability − 16 (illegality penalty) = 28 ± 8 (Theoretical only; deck cannot be played in Master Duel format as constructed)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.75 · key two-card combo ≈ 0.45 · full-brick estimate ≈ 0.16 (all Inferred)
• Combo output: best PowerIndex 58, median 48, board-per-starter 1.8
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Rikka core searcher engine (Glamour, Mudan, Petal) generates consistent value and field presence
• Lonefire Blossom loops enable tutor access and extended lines into Extra Deck
• GY recursion (Rose Lover, Spore, Rikka Petal) provides recovery and grinding tools
• Sunavalon Link monsters (Melias, Dryatrentiay) deliver layered negation and field effect control
• Flexible summoning: Unexpected Dai and Sunvine Sowing bypass hand reliance

Weaknesses

• Deck is ILLEGAL: runs 3 Maxx "C", 2 That Grass Looks Greener, 2 Called by the Grave when Master Duel limit is 1 copy each
• Only 28% of archetype standard core present; missing Sunavalon Dryas (×2–3 standard vs. 0 in deck), Humid Winds, Blessed Winds, critical Extra Deck coverage
• 60-card Main Deck (non-standard) significantly reduces opening consistency and increases brick frequency
• Median combo output modest and vulnerable to single interruption; no robust multi-path recovery
• Heavy reliance on Rikka searchers; if disrupted early, deck stalls
• Low offensive power: bosses are 0–2400 ATK, no piercing or direct damage; grinds slowly toward win

Critical choke points

• Turn-1 Rikka starter (Petal/Glamour/Mudan) — if not resolved, entire line collapses into hand-trapped board
• Extra Deck Link access — missing Sunavalon Dryas forces reliance on Melias; if Melias negated, recursion loop breaks
• Banlist violations invalidate the deck under Master Duel format rules; evaluation is theoretical only

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (3 violations: over copy limits on Maxx "C", That Grass Looks Greener, Called by the Grave); Deck size: 60 Main, 15 Extra, 0 Side (confirmed from evidence.json); Archetype core coverage: 7/25 standard cards present = 28% (from usage statistics); Card text for all 39 distinct cards (resolved from card records); Banlist status per card (verified against BanMasterDuel field)
• Observed: Rikka searcher count: 3 Glamour + 3 Petal + 1 Mudan + 3 Lonefire = 10 tutors in 60-card deck
• Inferred: P(≥1 archetype core in opening 5) ≈0.749 from hypergeometric with 14 core copies in 60-card deck; Full brick estimate ~16–18% (60-card size, 12 triples, 6 doubles, 12 singles, low consistency); Combo ceiling PowerIndex ≈58 from Sunavalon Dryatrentiay (Link-4) + Rikka negation + 1–2 float; Combo median PowerIndex ≈48 assuming one interruption and sub-optimal line continuation; Median output board per starter ≈1.8 Link monsters + interaction; Going-First Power ≈58 (Melias negation + Rikka coverage setup); Going-Second Power ≈54 (Sunvine Sowing tool + Unexpected Dai fallback; limited spot removal); Tournament Reliability ≈42 (brick rate, single choke-point Rikka dependency, post-disruption collapse)
• Provisional: Meta Power: null (no dated metagame sample; archetype meta-share unavailable in tournament data); Matchup outcomes: unknown (no tournament link, no pilot record)
• Data gaps: No combo boards parsed (combo data.total combos = 0): floor/median/ceiling inferred from text only No tournament link: archetype meta-share and per-pilot match record unavailable No metagame sample supplied: Meta Power cannot be computed; remains Provisional No win-rate telemetry in YGOVN: brick rate, going-first/second splits, matchup frequencies all Inferred from probability estimates No Side Deck provided: post-side plan cannot be evaluated (Master Duel: 0 side cards) No strategy guide snippets: pilotability inferred from card complexity alone
