Ars Magna Deck #766161 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Ars Magna / Power Patron Link board converting into 3000-ATK ritual and Extra-Deck boss monsters (Black Chaos, Black Luster Soldier, Chaos Angel); Light and Darkness Ritual recursion into Black Chaos or Magician of Dark Chaos
• Turn 1 (going first): Starter via Ars Magna / Mulcharmy / Light and Darkness Ritual searches, then Link into Power Patron to extend; hand traps held for the opponent's first interaction
• Turn 2 (going second): Ash Blossom / Droll & Lock Bird / Kuriboh interrupt the opponent's first search or summon, then Medius / Theorealize recovery into a Power Patron board
• Recovery: Mulcharmy Fuwalos/Purulia draw engine and Medius/Theorealized Medius recursion from the GY and banishment
• After siding: Not evaluable: side deck is empty (0 cards)

Why it scores here

The deck's archetype core (17 copies of Ars Magna, Mulcharmy and Light and Darkness Ritual cards) has a Hypergeometric estimate of about 94% to have at least one core starter in a 5-card opening hand, so the engine reliably opens (Inferred). Interaction is dense for a Midrange list: five hand traps, Droll & Lock Bird and Kuriboh give several going-second answers, and the Extra Deck carries multiple boss monsters at 2800-3500 ATK, so the closing power is credible. The deck's weaknesses are structural rather than card-quality: only 10.7% of main-deck cards share the exact Ars Magna name, the archetype spread runs across several sub-archetypes, and there are no recorded boards, so the median output cannot be measured. The score is not driven by Ars Magna being a popular archetype and was not computed by averaging individual card scores. The list is illegal (Ash Blossom over its copy limit) and has no side deck, so the result is capped and labelled theoretical/structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 50, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12); no_side_deck (0). Final formula: Illegal cap applied: uncapped 0.80*Structural(54) + 0.20*TournamentReliability(40) = 51; capped to 30 as theoretical/structural-only because the list is illegal (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core engine opens in about 94% of 5-card hands (Inferred)
• Five hand traps plus Droll & Lock Bird and Kuriboh give going-second coverage
• Extra Deck boss monsters at 2800-3500 ATK give closing power

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring over its copy limit
• No side deck
• Low exact-name purity (10.7%); the engine spreads across several sub-archetypes
• No recorded boards, so the median and ceiling are inferred from text only

Critical choke points

• Single Power Patron Link board as the conversion point for the Ars Magna plan
• Ash Blossom over-limit copy makes the list unplayable as built until fixed

Recommended changes

Evidence & confidence

• Verified: Main 41 / Extra 15 / Side 0 are within size rules; Ash Blossom & Joyous Spring runs 3 copies vs 2 legal (Semi-Limited); S:P Little Knight is Limited at 1 copy; Extra Deck breakdown: 9 Link, 4 Fusion, 2 Synchro
• Inferred: P(at least one archetype core card in 5-card hand) ≈ 0.94; Going-second hand-trap coverage ≈ 0.57; Dimension scores D1-D3, D5-D9, D11, D14
• Provisional: Meta Power (null); D13 matchup and format fit
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck supplied Deck title is null
