Ars Magna Deck #770570 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±6 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro/Link/Fusion boss monsters (Clear Wing, Chaos Angel, Stardust Sifr, Cosmic Blazar, Vidolium) closing through Power Patron and Ars Magna link pressure; Elfnote and Mulcharmy draw-and-board engines that rebuild after disruption
• Turn 1 (going first): Open on Elfnote or Mulcharmy starters, search Ars Magna or Elfnote enablers, and build toward a Link or Synchro boss; hand traps held up for the opponent's first activation
• Turn 2 (going second): Use the 76% chance of at least one hand trap in a six-card hand to interrupt the opponent's first board, then rebuild through Mulcharmy draw effects and Elfnote searches
• Recovery: Recover through Ars Magna searchers and Theorealize Past Lull, Junoldo and Medius recursion, and Mulcharmy draw effects
• After siding: Not applicable: the deck runs zero side-deck cards, so there is no defined post-side plan

Why it scores here

This list is capped as an illegal deck: it runs three Elfnote Lucina against a limit of one and three Ash Blossom & Joyous Spring against a limit of two, so the score reflects structural strength only and is not a normal Final Contextual score. On the system, the 21-copy Ars Magna and Elfnote core gives an archetype-core opening probability of about 0.92 (Inferred), and the 22 searcher-text cards and 11 hand traps give resilience and going-second interaction. The end-board is backed by several 3500–5000 ATK bosses and 11 negation-text cards. The deck has no recorded combos, no tournament link, and no side deck, so the floor and median are weakly supported. Popularity and archetype usage stats confirm the list is real but do not raise the score, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-6); Engine conflicts (-4); No side deck (-2). Final formula: Structural 56 and TournamentReliability 45 give 0.80*56 + 0.20*45 + modifiers(-12) ≈ 42 before the legality cap; the deck is Illegal, so the score is capped at 25 and labelled theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Core archetype group is highly accessible (about 0.92 at least one in a 5-card hand, Inferred)
• Layered interaction: 11 hand traps, 11 negation-text cards, and 28 removal-text cards
• Strong Extra Deck boss density (Vidolium 5000, Stardust Sifr 4000, Cosmic Blazar 4000)
• Recursion and searchers (Junoldo, Medius, Theorealize Past Lull, Mulcharmy draw) support recovery

Weaknesses

• Illegal copy counts: Elfnote Lucina ×3 (limit 1) and Ash Blossom ×3 (limit 2)
• Low archetype purity (12.9%), so engines conflict across sub-archetypes
• No side deck, so no post-side adaptability
• No combo data, so the median output is unsupported
• High execution load across multi-step Link and Synchro lines

Critical choke points

• Any single legal-copy correction changes the starter density for the Elfnote engine (Lucina is capped at 1)
• Synchro and Link boss lines depend on Power Patron Link and Ars Magna Link presence in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Legality: Elfnote Lucina over the Limited limit (3 vs 1); Ash Blossom over the Semi-Limited limit (3 vs 2); Main 55 and Extra 15 are within size rules (40–60 and 0–15); Usage stats: Ars Magna core inclusion and Ash Blossom typical copies 3 (usage, not legality); Archetype purity 12.9%; 16 distinct singletons; 11 hand traps; 22 searcher-text cards
• Observed: No observed combo or win-rate data exists for this deck
• Inferred: P(at least one core-archetype card in a 5-card opening hand) ≈ 0.92; P(at least one hand trap in a 6-card opening hand) ≈ 0.76; Going-second hand-trap interaction and Mulcharmy draw recovery add resilience; Engine conflict across sub-archetypes lowers consistency
• Provisional: Meta Power and matchup fit: no dated metagame sample, no tournament link
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and the deck has no side deck Ash Blossom and Elfnote Lucina copy counts exceed legal limits, so a normal Final Contextual score is withheld
