Sunseed Deck #57598 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Establish Plant-synergy board with Link monsters and removal/negation interaction; Go-second board break via hand traps and disruption cards
• Turn 1 (going first): Summon Sunseed Genius Loci and establish Sunavalon Link summon to generate value and board pressure
• Turn 2 (going second): Use Ash Blossom, Maxx C, Evenly Matched, and Dark Ruler No More to disrupt opponent, then pivot to offense
• Recovery: Rikka Petal and Rikka Glamour provide recursion; One for One enables Level 1 summons from Deck
• After siding: Unknown—no side deck provided; theoretical structural evaluation only

Why it scores here

This deck is structurally compromised by illegality (Maxx C and Called by the Grave over copy limits in Master Duel format) and achieves only a theoretical evaluation. The core engine (Sunseed Genius Loci, Rikka Petal, Rikka Glamour, Unexpected Dai) can generate a turn-1 board with Sunavalon Links and interaction pieces, but at 32% purity against 25 core cards it lacks the dense engine synergy of optimized Sunseed-Sunavalon lists. Hand-trap density (14 copies) provides going-second disruption, but the median combo output is modest due to limited starter redundancy (only 8 of 25 core cards present) and reliance on Normal Summoning mid-sized bodies. The deck's recovery via recursion is fragile—Rikka Petal and Rikka Glamour provide loops but no protection from repeated interruption. No side deck exists to boost going-first resilience or post-side pivots. High brick risk, weak grind game, and suboptimal Extra Deck coherence (Aromaseraphy Jasmine, Hyperyton, Benghalancer present but underutilized) prevent a higher structural score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 33, Going First ≈ 36, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 26. Modifiers: Illegality penalty (-8); Core engine dilution (-5); Oversized main deck (-3). Final formula: Illegal deck: 0.80 × Structural (33) + 0.20 × TournamentReliability (26) + Illegality penalty (−8) = 32. Meta = Provisional (no dated sample). Confidence Low due to illegal list, missing combo data, no tournament link, and no side deck.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.78 · key two-card combo ≈ — · full-brick estimate ≈ 0.22 (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 (14 total: Ash, Maxx C, Nibiru, Evenly Matched, Red Reboot) provides strong going-second disruption potential
• Rikka engine (Glamour, Petal, Princess) enables modest recursion and search loops within the Plant type
• Dual-path Sunavalon/Therion integration offers flexibility in boss-monster selection (Dryas, Melias, Hyperyton)
• Extra Deck includes multiple Link options (11 cards) to pivot between control and offensive strategies

Weaknesses

• Illegal in Master Duel format: Maxx C (3 copies, max 1) and Called by the Grave (2 copies, max 1)
• Core engine severely diluted: only 32% of optimal Sunseed-Sunavalon core present (8/25 cards); missing Sunavalon Dryas, Daphne, Melias, Sunvine Thrasher/Healer
• Oversized main deck (56 cards) with high garnet density (Level 8 bodies, Cactus Bouncer, Primula) creates brick hands and dead-weight draws
• No side deck provided; theoretical build cannot adapt post-match
• Weak offensive pressure: no direct-damage, piercing, or forced-win mechanics; ATK output relies on mid-sized bodies (2400–2800)
• Single Rikka Glamour is a choke point for search; loss of one search line severely impacts recovery
• Combo median output modest due to limited starter redundancy (only 8 core cards); no robust alternative lines observed

Critical choke points

• Rikka Glamour is the only reliable searcher for Rikka cards; negate or removal of this card breaks the main loop
• Sunseed Genius Loci (Normal Monster, 3 copies) is the primary T1 starter; hand without it forces reliance on Unexpected Dai or One for One, both conditional
• Oversized 56-card main with conflicting Normal Summons (Rikka Princess blocks Level 4 Normal Summons, Aromage Jasmine requires higher LP) creates decision paralysis and brick risk
• Missing Sunavalon Daphne and key Sunvine cards (Thrasher, Healer) removes redundant combo paths; board reliant on single Sunavalon Dryas (3 copies in Extra, but not in Deck core)
• No protection from repeated disruption: once hand traps are exhausted, the fragile GY loop (Petal + Glamour) lacks follow-up redundancy

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Maxx C 3 run vs. 1 legal; Called by the Grave 2 run vs. 1 legal); Main deck size: 56 cards (exceeds 40-min default but within 40-60 range for Master Duel); Extra Deck: 15 cards (at max capacity, format rule); Card text confirmed for Rikka Princess, Rikka Petal, Rikka Glamour, Sunseed Genius Loci, Unexpected Dai, One for One; Usage statistics available: archetype core-presence rate 32% (8/25 cards present); Master Duel banlist: Maxx C Limited (1), Called by the Grave Limited (1)
• Observed: Archetype spread: Rikka (18 copies), Sunseed (4), Sunvine (4), Therion (4), generic/tech (27); Hand-trap count: 14 distinct copies (3× Ash, 3× Maxx C, 3× Nibiru, 3× Evenly Matched, 2× Red Reboot) for going-second; Extra Deck composition: 11 Links, 4 Xyzs; Sunavalon Dryas 3× present in list, but core Sunavalon engine cards missing from main; Role-hint composition: 14 negation-text cards, 11 searcher-text cards, 10 removal-text cards
• Inferred: P(≥1 starter in hand 5) ≈ 0.78 using hypergeometric; effective startup reliability ~65% accounting for conditional starters; Full brick estimate ~0.22 (22% of hands draw no starters due to Level 8 body/tech density); Combo median ceiling: ~40–45 Power Index (typical Sunavalon Link into 1–2 negations); no robust alternative lines due to missing Daphne/Melias; Going-first board: 1–2 Link monsters + 1 negate/search piece; ~3–4 summons on T1 with Glamour loop; Going-second board-break power: 6-card hand with 14 hand-trap copies yields ~60–70% disruption success vs. combo-heavy opponents; Grind game weakness: Rikka loops provide card advantage but no protection from negate/removal; post-disruption recovery fragile; Tournament reliability: Low (~26/100) due to oversized main, single Glamour choke point, and lack of side deck
• Provisional: Meta Power: null—no dated metagame provided; Sunseed is casual mid-tier archetype, likely 2–5% format share in Master Duel; Format fit: Master Duel speed/tier unknown; assumed mixed-speed environment without dated meta sample; Post-side performance: 0 (no side deck); estimated post-side T1 resilience would improve if side deck added with defensive techs
• Data gaps: No parseable combos supplied—combo floor, median, ceiling, board-per-starter all inferred from card text only No tournament link or win-rate telemetry—Meta Power and going-first/second win rates unknown No side deck—post-side adaptability cannot be scored; all side-related recommendations are structural No dated metagame sample—matchup outcomes and meta share speculative Illegality status prevents normal evaluation—score is theoretical/structural only No guides or archetype strategy resources attached—intended pilot play patterns inferred from card roles
