Ars Magna Deck #766158 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link/Synchro boards from Power Patron and Ars Magna monsters (Mediclius, Vidolium, Purification, Accesscode) converting into link-beats and tripled ATK; Elfnote Lucina and Tinia are the big bodies.; Hand-trap-supported Synchro and Xyz boards (Galaxy-Eyes Photon Lord, Varudras, Crystal Wing) once the opponent's interaction is spent.
• Turn 1 (going first): Open a starter from the Ars Magna / Elfnote core (archetype core ≈ 0.91 at least one in a 5-card hand), search a Power Patron or Elfnote engine piece, and build a Link or Synchro board into a Power Patron link.
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Ghost Ogre, Kuriboh and Infinite Impermanence to disrupt the first summon or search, then rebuild through Mulcharmy draw and Elfnote searches.
• Recovery: Mulcharmy draw effects and the Ars Magna / Theorealize search chain (Medius, Theorealize Past Lull, Pendulum Treasure) to refill the hand after a board is removed.
• After siding: Not available: the deck runs no Side Deck (side_count 0), so there is no post-side plan.

Why it scores here

This list is Illegal in TCG: Elfnote Lucina is run 3 times against a limit of 1, and Ash Blossom & Joyous Spring is run 3 times against a limit of 2, so the score is capped at a theoretical/structural read of 30 rather than a normal Final Contextual score. Structurally the deck opens its engine reasonably often, since the archetype core has an estimated 0.91 chance of at least one piece in a 5-card opening hand, and it carries 14 hand traps and 21 removal-text cards for interaction. Its weaknesses are a low archetype purity (8% exact name, with Mulcharmy, Elfnote, Power Patron, Medius and Kuriboh sub-engines competing for the same slots), Mulcharmy cards whose effects depend on controlling no cards, a 15-card Side Deck absence, and no recorded boards to measure the median output. Popularity of the Ars Magna core in usage statistics confirms the list is real, but it did not earn points by itself, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 48, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: Illegal: theoretical cap. Pre-cap = 0.80*Structural(51) + 0.20*TournamentReliability(42) + modifiers(-12) = 38; capped at 30 because the deck is Illegal. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• Archetype core is accessible: about 0.91 chance of at least one core piece in a 5-card opening hand
• Layered interaction: 14 hand traps and 21 removal-text cards, with strong going-second disruption
• Link and Synchro closing options (Mediclius, Vidolium, Purification Power Patron)

Weaknesses

• Illegal copy-limit violations on Elfnote Lucina and Ash Blossom & Joyous Spring
• Low archetype purity (8%) spreads the deck across several sub-engines
• Mulcharmy cards depend on an empty board and conflict with board-based engines
• No Side Deck, so no post-side plan

Critical choke points

• Single-card dependence on Elfnote Lucina or Ash Blossom for interaction once the limit is corrected
• Power Patron Link Summon line needs a Power Patron in the GY or a DARK Fairy on the field

Evidence & confidence

• Verified: Legality: Lucina 3 copies vs 1 legal, Ash Blossom 3 copies vs 2 legal (Illegal); Main 60 / Extra 15 / Side 0 composition; Archetype purity 8%; 14 hand traps; 27 searcher-text cards; Archetype-core usage statistics
• Inferred: Archetype-core accessibility ≈ 0.91 in a 5-card hand; Hand-trap coverage ≈ 0.81 in a 6-card hand; Interaction layering and going-second profile from card text; Mulcharmy engine conflict from card text
• Provisional: Meta-share and format fit (D13); no dated metagame sample supplied
• 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, matchup or brick rates Meta Power is provisional unless a dated metagame sample is supplied No Side Deck: post-side plan cannot be assessed
