Ars Magna Deck #770514 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Midrange, Synchro/Link/Fusion mechanic mix
• Format: tcg

Legality

Main 54 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Link/Synchro boards built on Power Patron Links (Mediclius, Purification) and Stardust/Galaxy-Eyes/Zalen Synchro bosses, with Ars Magna and Elfnote engine cards supplying summons and recursion; Elfnote Seraphim Strelitzia and Elfnote June Pride as Synchro pressure from Elfnote Power Patron / Junoldo searches
• Turn 1 (going first): Opening Mulcharmy Fuwalos/Purulia draw-and-search turns and Elfnote Regina/Lucina searches toward a Synchro or Link board; the deck's hand traps (Ash Blossom, Infinite Impermanence, Ghost Ogre, Ghost Belle) are held for the opponent's first activation
• Turn 2 (going second): Six-card hand with 13 hand traps (P(at least one hand trap in 6) ≈ 0.83) to interrupt the opponent's first engine; then Medius/Theorealize searches toward a board-breaking Extra Deck summon
• Recovery: Ars Magna and Elfnote monsters banished or sent to the GY for recursion (Ars Magna Philosophorum, Theorealize Past Lull, Elfnote Fortuna), Mulcharmy draw engine for card advantage
• After siding: None: the Side Deck is empty, so there is no post-side plan in the list as submitted

Why it scores here

This list is Illegal as submitted: Elfnote Lucina is run 3 times against a Limited cap of 1, Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited cap of 2, and the Extra Deck holds 17 cards against a maximum of 15. Under the rubric it therefore receives a structural-only read capped at 25, and this is not a normal Final Contextual score. The engine itself is fairly coherent on paper: the 22-card archetype core has a hypergeometric P(at least one core card in a 5-card opening hand) of about 0.94, and 13 hand traps give strong going-second interaction. Consistency and interaction are scored as inferred from card text and probability, because no recorded boards, tournament results, or guides exist for this deck. Only 9.9% of the main deck uses the exact name 'Ars Magna', and the list spreads across Elfnote, Mulcharmy, Power Patron, Stardust, Medius and Junk sub-archetypes, which lowers pilotability and Extra Deck efficiency. Popularity was not credited and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: copy-limit violation (-6); extra deck over size (-3); banlist exposure (-3); illegal cap (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 47.2 before modifiers; modifiers total -12 gives 35.2; Illegal cap applied, final 25 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Large archetype core (22 cards) with a high opening-hand presence (≈0.94 for at least one core card in 5)
• 13 hand traps and 14 negation-text cards give strong interaction, especially going second
• Multiple searchers and Mulcharmy draw engines give card advantage

Weaknesses

• Illegal as submitted: copy-limit violations and Extra Deck over size
• Exact-name purity only 9.9%; the list spreads across at least six sub-archetypes
• Empty Side Deck means no post-side adaptability
• No recorded boards, so the combo ceiling and median are unverified

Critical choke points

• Elfnote Lucina and Ash Blossom cannot be legally run at 3 copies, so the list must be cut before it is playable
• Extra Deck must lose 2 or more cards to be legal, and the Synchro/Link cut will affect the boss lines
• No Side Deck and no alternate win condition if the Power Patron Link line is stopped

Recommended changes

Evidence & confidence

• Verified: Illegal status: Elfnote Lucina 3 copies vs Limited 1; Ash Blossom 3 vs Semi-Limited 2; Extra Deck 17 exceeds the TCG maximum of 15; Side Deck is empty (0 cards); Exact-name archetype purity 9.9%; 22-card archetype core
• Inferred: Core-starter opening-hand probability ≈ 0.94 (hypergeometric); Going-second hand-trap presence ≈ 0.83 (hypergeometric); Interaction and brick-rate reads from card text
• Provisional: Meta Power and format fit are null or provisional (no dated metagame sample)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchups, or brick/starter rates Meta Power is provisional without a dated metagame sample No guides for the archetype (guide data total 0) Side Deck empty: no post-side evidence
