Ars Magna Deck #774081 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Board pressure from Power Patron / Ars Magna Link and Fusion threats (Vidolium, Nerva, Mediclius, Diactorus) backed by Light and Darkness Ritual bosses (Black Chaos, Magician of Dark Chaos, Black Luster Soldier); Draw-engine attrition through Mulcharmy and Medius recursion
• Turn 1 (going first): Pendulum Treasure or Medius the Pure as the opener, then a Power Patron Link or Ars Magna search to reach a board; hand traps held for the opponent's first activation
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Kuriboh, Nibiru, Droll & Lock Bird) and Solemn Judgment to stop the opponent's first board, then a Ritual or Link line to rebuild
• Recovery: Ars Magna and Theorealize recursion from the GY and banishment; Medius and Theorealized Medius re-summon the engine after a disruption
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck opens reliably on paper: the core archetype group (25 copies) has about a 94% chance of at least one card in a 5-card hand, and Medius, Pendulum Treasure and Mulcharmy give several starters. Its interaction density is high, with 10 hand traps, 12 negation-text cards and 33 removal-text cards, which supports the resilience and going-second scores. Its endboard ceiling comes from several 2800-5000 ATK threats, but no recorded boards exist, so the floor and median are scored low and labelled Inferred. The deck is an Illegal list (Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2), so it receives a structural-only score capped low instead of a normal Final Contextual score. Popularity was not credited: the archetype usage stats confirm a real, accessible list, not strength, and the card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary; weights taken from the Midrange row. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: illegal copy-limit cap (-10); no side deck (-2). Final formula: Illegal list: structural-only. 0.80*Structural(52) + 0.20*TournamentReliability(42) = 50, then context modifiers -12 (illegal copy-limit cap -10, no side deck -2) = 38. Meta provisional.

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

• Dense interaction: 10 hand traps, 12 negation-text cards and 33 removal-text cards
• Several high-ATK closing threats across Link, Fusion, Synchro and Ritual
• Multiple starters with a high archetype-core hit rate
• Recursion through Ars Magna and Theorealize from GY and banishment

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring runs 3 copies against a limit of 2
• Low archetype purity (8.1% exact name) across about 18 sub-archetypes
• No side deck, so no post-side plan
• Many conditional or dead-in-hand cards (Mulcharmy, Medius, hand traps) raise brick risk
• High pilot complexity across ritual, pendulum, link and fusion steps

Critical choke points

• Ash Blossom & Joyous Spring copy count must drop to 2 to make the deck legal
• Medius the Pure as the main engine bridge into Power Patron and Theorealize lines
• Ritual summons depend on Light and Darkness Ritual, which is a single copy

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring runs 3 copies, legal limit 2; Main 59, Extra 15, Side 0 are within the TCG size rules; Archetype exact-name purity 8.1%; Core group of 25 copies: P(>=1 in 5) = 0.9444
• Inferred: Starter access and brick risk from hypergeometric draw odds and card text; Interaction quality from hand-trap and negation text counts; Going-first and going-second estimates from the function scores; Closing power from the listed ATK values and text
• Provisional: Meta Power is null; tournament share and dated meta are absent; Matchup fit (D13) placed at a provisional value
• Data gaps: No combos supplied, so the combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null No side deck list
