Ars Magna Deck #773493 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 43 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link and Xyz pressure from Power Patron / Ars Magna monsters, with Vidolium and Gustav Rocket as high-ATK closers; Fusion and Synchro boards (Nerva, Junora) that negate and lock the opponent's field
• Turn 1 (going first): Pendulum Treasure or Ars Magna searchers into Medius / Ars Magna Effect Monsters, then Link or Fusion Summon to build a negating board
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Ghost Ogre and Infinite Impermanence to answer the opponent's starter, then rebuild through Medius and Ars Magna searchers
• Recovery: Recursion through Medius and Theorealize Overdrive, plus Ars Magna monsters that return from the GY or banishment
• After siding: No side deck is listed, so no post-side plan exists in this build

Why it scores here

The deck reliably finds a starter: the searcher group (22 copies) gives about a 98% chance of at least one in a five-card opening hand, and the 19-copy Ars Magna / Power Patron core gives about 96% (Inferred, hypergeometric). Its 12 hand traps (Ash Blossom, Ghost Ogre, Effect Veiler, Infinite Impermanence, Droll & Lock Bird) give strong interaction density and about 88% chance of at least one going second (Inferred). Conversion is the weak point: no recorded boards exist, so the ceiling and median are text-only reads and the median is held down by 50 off-archetype copies (13.8% exact-name purity). The score comes from consistency, interaction and closing power on the system, not from Ars Magna being a popular archetype and not from averaging card scores. The deck is illegal as built (three copies of Ash Blossom against a limit of two, Semi-Limited), so the final score is capped and the evaluation is structural only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violation (-12). Final formula: Structural 59 and TournamentReliability 40 give 0.80*59 + 0.20*40 = 55.2; illegal-deck modifier -12 gives 43; the illegal-deck cap sets the final score to 35 (theoretical / structural-only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Searcher density (22 cards) keeps the engine live in most openings
• Twelve hand traps and negates give high interaction density on both turns
• Extra Deck is full (15/15) with multiple Link, Fusion and Xyz closers

Weaknesses

• Illegal as built: Ash Blossom run 3 copies against a limit of 2
• Low archetype purity (13.8%): 50 off-archetype copies dilute the engine
• No side deck, so there is no post-side adaptation

Critical choke points

• Ash Blossom over the copy limit must be cut to 2 before the list is playable
• Medius and Pendulum Treasure as the main bootstrap routes

Recommended changes

Evidence & confidence

• Verified: Main 43 / Extra 15 / Side 0 counts fall within the TCG size rules; Ash Blossom & Joyous Spring run 3 copies against a legal limit of 2 (violation); Composition and copy histogram: 22 distinct main, 14 distinct extra, 10 singletons; Exact-name archetype purity 13.8%; 50 off-archetype copies
• Inferred: P(>=1 searcher in 5 cards) ≈ 0.98 and archetype-core ≈ 0.96 (hypergeometric); Going-second hand-trap coverage ≈ 0.88; Interaction density and closing power read from card text excerpts
• Provisional: Meta Power and matchup fit: no dated meta sample or tournament link; Combo floor and median: no recorded boards
• 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; going-first/second, matchup and brick rates are Inferred or Unknown no side deck listed; post-side scoring not possible Meta Power is Provisional without a dated metagame sample
