Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Link and Synchro boards built through Elfnote and Power Patron engine chains, closing with high-ATK Link/Synchro monsters (Mediclius, Junora, Vidolium, Elfnote June Pride); Ars Magna recursion and Medius GY revival to rebuild boards after the opponent's interaction
- Turn 1 (going first): Opening starters (Elfnote Power Patron, Elfnote Regina, Medius the Pure, Effect Veiler and Ash Blossom as protection) into a Synchro or Link line; Ars Magna and Elfnote searchers keep the hand functional. Structural read only, no recorded boards.
- Turn 2 (going second): Hold 2-3 hand traps (Ash Blossom, Effect Veiler, Droll & Lock Bird) against the opponent's starter, then rebuild through GY and banished recursion. Structural read only.
- Recovery: Medius the Pure and the Ars Magna monsters revive from GY or banishment, and Elfnote Welcome Home style effects return monsters to the field. Inferred from card text.
- After siding: No side deck is supplied (side_count 0). No post-side plan can be evaluated.
Why it scores here
This Ars Magna list is illegal as submitted: Elfnote Lucina is run 3 times against a Limited cap of 1, and Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited cap of 2. Its structure still reads as a coherent multi-engine Midrange shell. Elfnote and Power Patron starters, Ars Magna and Medius searchers, and seven hand traps give a plausible opening and interruption package. The score comes from consistency and interaction on the system, not from Ars Magna's popularity (archetype core copies are high, but that only confirms the list is real). Card scores were not averaged. No combos, tournament record, guides or side deck were supplied, so median and ceiling output are text-based inference and the score is capped as theoretical/structural only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 of a 3-copy starter in 5-card hand) = 0.338; archetype core group (29 copies) P(open >=1) = 0.9993; 2-card bootstrap plausible but unmeasured (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 7 hand traps and 23 searcher-text cards help, but several Extra-dependent engines and 3-copy starters create conflicting hands; no brick estimate computed (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Ceiling inferred from text only: Power Patron Link chains and Synchro boards, with no recorded boards to measure output (Inferred) |
| D4 | Combo Floor & Median Output | 48 | Median output unknown: combos_evidence is empty (total_combos 0), so the floor is set by text-only inference (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 66 | 7 hand traps, Ash Blossom, Effect Veiler and Droll & Lock Bird, plus Medius and Ars Magna GY/banish recursion give independent continuation routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 64 | 23 searcher-text cards and recursion effects (Ars Magna, Medius, Elfnote) support rebuilding; no resource signature available (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | 7 negation-text cards and 16 removal-text cards, plus Effect Veiler and Ash Blossom as hand traps; no end-board data (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 68 | Going-second hand trap probability P(>=1 hand trap in 6 cards) = 0.711; going-second split not measured (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Vidolium (5000 ATK base) and Link/Synchro bosses around 3000 ATK give closing power on paper; no end-board ATK or damage data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 40 main cards with 22 distinct; exact archetype purity is only 12.7% across 15 sub-archetypes, so coherence is mixed (Verified composition, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 58 | 15 Extra Deck cards, all singletons, spread across Link, Synchro, Xyz and Fusion; Extra summon access comes from main-deck engines (Verified composition, Inferred access) |
| D12 | Side Deck Adaptability | 25 | No side deck (side_count 0); post-side adaptability cannot be assessed and is scored as a gap (Provisional) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link and no dated metagame sample; archetype meta-share not available (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-engine line with Link, Synchro and recursion decision points is high-complexity, and a single misplay risks the chain (Inferred) |
How the score was computed
Strategy profile: Midrange primary; Toolbox secondary for hand traps and tech as role evidence. Structural ≈ 57, Going First ≈ 58, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: Illegal cap: raw 0.80*Structural(57.4) + 0.20*TournamentReliability(50) = 55.9; modifiers total -12 give 44; deck is Illegal, so score is capped to 35 as theoretical/structural-only. Meta provisional.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Dense engine coverage: Elfnote Power Patron, Regina and Medius start chains, and the Ars Magna monsters search and recur
- Seven hand traps plus removal text give going-second interaction
- Archetype core is nearly always opened (P = 0.9993 for the core group)
- Multi-route Extra Deck with Link and Synchro bosses and Ars Magna boost text
Weaknesses
- Illegal list: two cards exceed their copy limits (Elfnote Lucina, Ash Blossom)
- No side deck, so there is no post-side plan
- Low exact archetype purity (12.7%) across many sub-archetypes raises conflict risk
- High complexity and no recorded combo data to confirm conversion
Critical choke points
- Elfnote Power Patron and Elfnote Regina as the first starter (3 copies each, P = 0.34 each in hand)
- Medius the Pure as the GY recursion route
- Legality: the list cannot be played in TCG until the two over-limit copy counts are fixed
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2x Elfnote Lucina (Limited, 1 legal copy), 1x Ash Blossom & Joyous Spring (Semi-Limited, 2 legal copies) | Non-Limited, non-Semi-Limited Elfnote or Power Patron engine cards, e.g. a second copy of Elfnote Fortuna (1 copy in deck, 3 legal), plus one extra Ars Magna monster as a flex slot | Restores legality first; the score cannot be a normal Final Contextual score while the list is Illegal |
| 2 | 1x low-impact tech or sub-archetype card outside the core engine | A 15-card side deck (side_count is 0, min 0 max 15) | Gives a post-side plan and improves the side-deck score (D12) for best-of-3 play |
Evidence & confidence
- Verified: Legality: 40 main, 15 extra, 0 side; violations for Elfnote Lucina (3 vs 1 legal) and Ash Blossom (3 vs 2 legal); Copy histogram and type/attribute/race spreads; Hypergeometric draw probabilities; Archetype core inclusion (29 copies, 99.93% opening probability)
- Inferred: Engine consistency and brick estimate; Interaction density from card text; Going-second hand-trap probability; Closing power from ATK values
- Provisional: Meta power and format fit: no dated metagame sample; Post-side plan: no side deck supplied
- Data gaps: no combos supplied (combos_evidence.total_combos = 0): combo floor/median/ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no side deck (side_count 0): post-side plan cannot be evaluated no win-rate telemetry; going-first/second and matchup signals are Inferred Meta Power is Provisional unless a dated metagame sample is supplied Illegal list: score is capped as theoretical/structural-only
