Ars Magna Deck #770467 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Power Patron and Elfnote boss monsters (Vidolium, Mediclius, Elfnote June Pride, Junora) built from the Ars Magna and Elfnote engine, with hand traps protecting the board; Synchro and Link beatdown off the Extra Deck after the Elfnote and Power Patron engine is online
• Turn 1 (going first): Open with an Elfnote or Ars Magna starter, search the next engine piece with the searcher monsters, and set up one hand trap and one floodgate-style negate line
• Turn 2 (going second): Use the 15 hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Ogre, Kuriboh, Nibiru) to stop the opponent's first summon chain, then convert into a Synchro or Link board
• Recovery: Recover from a broken hand by banishing Ars Magna cards from the hand for searches and using GY-based Medius and Theorealize recursion
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adjust between games

Why it scores here

The deck reliably opens its engine: the Ars Magna and Elfnote core (20 copies) gives about a 0.90 chance of at least one core card in a 5-card opening hand (Inferred hypergeometric estimate), and 21 searcher-text cards add redundancy. Its interaction layer is dense, with 15 hand traps and 14 negation-text cards, which supports the end-board score. Conversion and floor scores are held down because no combo boards were recorded and the output of the Power Patron and Elfnote bosses is only text-inferred. The deck has no side deck and runs six cards that are illegal or over the copy limit, so the Final score is capped low and the evaluation is structural only. The score comes from consistency and interaction on the system, not from Ars Magna being a popular archetype and not from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54.4, Going First ≈ 56, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-6); no_side_deck (-3); illegal_cap (-14.5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 53.5 before modifiers; the illegal cap reduces it to 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.1 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• The archetype core opens in about 90 percent of 5-card hands (Inferred)
• Fifteen hand traps and 14 negation-text cards give dense interaction (Verified text, Inferred quality)
• Searcher density of 21 cards gives redundancy for the engine (Verified text)

Weaknesses

• Illegal list: three Forbidden cards and three over-limit cards must be removed before this deck can be played
• No side deck, so no post-side adaptability
• Low exact-name purity (5.6 percent) across 16 sub-archetypes weakens engine coherence
• No recorded combo boards, so conversion and median output are unmeasured

Critical choke points

• The Power Patron and Elfnote boss monsters depend on a small set of Extra Deck pieces; losing them removes the main win condition
• Forbidden Elfnote Tinia and F.A. Dawn Dragster are structural pieces, and removing them changes the engine

Recommended changes

Evidence & confidence

• Verified: Legality is Illegal: three Forbidden cards and three over-limit copies (legal_copies field); Main 57, Extra 15, Side 0; main size is within the 40-60 range; Role-tag counts: 15 hand traps, 21 searchers, 14 negation, 22 removal
• Inferred: Archetype core opens in about 90 percent of 5-card hands (hypergeometric); Interaction density is high on the system (semantic read of card text); Engine conversion is plausible but unmeasured
• Provisional: Meta Power is null: no dated metagame sample is supplied; Matchup and format fit are provisional because no tournament data is linked
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record are absent No win-rate telemetry in YGOVN: going-first, going-second, and matchup rates are unknown Meta Power is provisional until a dated metagame sample is supplied No side deck registered: post-side plan cannot be evaluated
