Legality

Main 49 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

  • Win condition: Link-monster board (Ragnaraika Stag Sovereign, Ragnaraika Chain Coils, Ragnaraika Selene Snapper) backed by Plant/Insect/Reptile recursion; Therion and Alsei/Teardrop Xyz boards from the Plant Graveyard engine (Inferred from text, no combo data)
  • Turn 1 (going first): Open a starter (Sylvan Cherubsprout, Snapdrassinagon, Effect Veiler, Ragnaraika the Evil Seed) with a hand trap held back, then Link Summon into a Ragnaraika Link
  • Turn 2 (going second): Hold 15 hand traps (Ash, Maxx, Droll, Infinite Impermanence, Effect Veiler, Ghost Ogre) to negate the opponent's first search or summon, then rebuild through Plant GY recursion
  • Recovery: Plant and Ragnaraika Graveyard effects (Spore, Glow-Up Bulb, World Carrotweight Champion, Ragnaraika Samurai Beetle) return monsters to the field after a hand-trap trade
  • After siding: Not evaluable: the export contains no side deck (Side Deck size 0)

Why it scores here

The deck is scored as a system: it has three-copy starters and a 15-card hand-trap and tech layer, so it opens a functional plan often enough and can answer the opponent's first search or summon, which earns the interaction and going-second points. Its Link Extra Deck (Stag Sovereign, Chain Coils, Selene Snapper, Mantis Monk) gives real closing power, and Plant/Insect/Reptile Graveyard recursion gives moderate recovery. Points are held back because there are no recorded boards, so the combo floor and median are Inferred from text only, and the many non-engine hand traps and techs create brick and dead-card risk. The score is not based on the Sylvans label, which shows 0% exact-name purity, and no card scores were averaged. The list is Illegal under OCG copy limits (Called by the Grave is Forbidden), so this is a structural-only reading capped by a -12 modifier, not a normal final score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 Three-copy starters and 2-copy hand-trap starters give P(>=1 starter in 5) around 0.28 per card and P(>=1 hand trap in 6) about 0.90 going second; no board data (Inferred)
D2 Opening-Hand Quality & Brick Management 50 15 hand traps and 17 tech cards with several non-engine copies create dead-hand risk when no hand trap or starter is live (Inferred)
D3 Combo Conversion & Ceiling 45 No parseable combos; ceiling is Inferred from Link and Xyz text (Ragnaraika Stag Sovereign, Alsei, Teardrop) and extra-deck routes (Inferred)
D4 Combo Floor & Median Output 40 No combo median or distribution available; floor relies on Graveyard recursion and hand-trap trades (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Plant/Insect/Reptile recursion (Spore, Glow-Up Bulb, Beetle, Bulb) and redundant starters give independent routes after one interruption (Inferred)
D6 Resource Economy, Recovery & Grind 55 Graveyard effects and searchers (Ragnaraika Bloom, Rose Girl, Therion Discolosseum) recover resources, but Limited and Forbidden copies make the engine thinner (Verified legality plus Inferred)
D7 End-Board & Interaction Quality 70 Negate-text cards (Ash, Maxx, Droll, Effect Veiler, Infinite Impermanence, Ghost Ogre) with 15 hand traps give layered interaction (Verified text plus Inferred semantic)
D8 Going-Second & Board-Breaking Power 65 Going-second hand-trap density is high, but no going-second combo split is recorded and no board-breaker count exists (Inferred)
D9 Offensive Pressure & Closing Power 65 Ragnaraika Stag Sovereign (3300 ATK), Chain Coils (2900) and Teardrop (2800) give strong closing boards (Verified stats)
D10 Main Deck Efficiency & Flexibility 50 49-card main with 17 tech and 3-copy spread across 29 distinct cards; no garnet structure and mixed sub-archetypes (Verified composition, Inferred)
D11 Extra Deck Efficiency & Coverage 65 12 Link and 3 Xyz monsters with four Ragnaraika Links cover many summon routes; one-copy flex slots (Verified composition, Inferred)
D12 Side Deck Adaptability 20 No side deck in the export (Side Deck size 0); no post-side plan can be evaluated (Verified, data gap)
D13 Matchup Coverage & Format Fit 40 No tournament link or dated meta sample; archetype share unavailable (Provisional)
D14 Pilotability & Error Tolerance 45 Multi-step Link and Plant recursion lines plus 15 hand traps needing timing decisions raise the decision burden (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal list (copy-limit violations, Forbidden card) (-12); No side deck in export (0). Final formula: Illegal: theoretical/structural-only. Structural 54 with Midrange weights; 0.80*54 + 0.20*45 = 52.2 before the -12 illegal-list modifier, rounded to 40.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.28 · 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

  • 15 hand traps and 12 negate-text cards give layered going-second interaction
  • Link Extra Deck with strong closers (Ragnaraika Stag Sovereign 3300, Chain Coils 2900, Selene Snapper 2600)
  • Plant/Insect/Reptile Graveyard recursion gives recovery after disruption

Weaknesses

  • Illegal under OCG copy limits: Called by the Grave is Forbidden and four other copy-limit violations
  • No side deck in the export, so no post-side plan
  • No recorded combos; floor and median cannot be measured
  • Sylvans archetype label has 0% exact-name purity; the list mixes Sylvan, Ragnaraika, Therion, Sunavalon and Rose

Critical choke points

  • Called by the Grave (Forbidden, 0 legal copies): must be removed entirely
  • Ragnaraika Link Monster in the Extra Deck: several Link routes depend on Ragnaraika-specific materials
Priority Remove Add Reason
1 Called by the Grave x2 Legal main-deck card (Sylvan or Ragnaraika engine piece) Forbidden in OCG; the list cannot be played as built
2 Ash Blossom & Joyous Spring x1, Maxx "C" x1, Droll & Lock Bird x1, Sunavalon Dryas x1 (Extra) Legal substitutes (one copy each) Bring the copy counts within the Semi-Limited and Limited caps
3 Off-archetype tech cards with no engine role Sylvan or Ragnaraika cards that continue the Plant recursion line Raise archetype purity and reduce brick risk

Evidence & confidence

  • Verified: Legality: 49 main, 15 extra, 0 side; five copy-limit violations including Forbidden Called by the Grave; Card text and stats from the evidence excerpts; Hypergeometric draw odds from the Main Deck
  • Inferred: Consistency and brick estimates for D1 and D2; Interaction quality from negate-text read; Going-first and going-second estimates
  • Provisional: Meta Power (null); Matchup and format fit (D13)
  • Data gaps: no combos supplied; floor, median and ceiling are text-only inference no side deck in the export; D12 and post-side plan unevaluable no tournament link; archetype meta-share and pilot record absent no win-rate telemetry; going-first and going-second splits are Inferred deck title is null Meta Power is Provisional without a dated metagame sample
