Ars Magna Deck #770430 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Power Patron Link, Synchro, Centur-Ion Legatia, Psychic End Punisher) reached through Ars Magna / Elfnote / Power Patron searches and Synchro or Link chains; Hand-trap and negation pressure that protects a single engine turn and forces the opponent to play around it
• Turn 1 (going first): Open a searcher (Elfnote Regina, Elfnote Power Patron, Ars Magna monsters) and use Mulcharmy Fuwalos or Elfnote Lucina to extend into a Synchro or Link boss; keep Ash Blossom and Effect Veiler up for the first interaction
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Effect Veiler (about 0.86 chance of at least one hand trap in six cards) to answer the opponent's starter, then rebuild through GY recursion from Medius and Theorealize Past Lull
• Recovery: Recur Medius the Pure and Theorealize Past Lull from the GY, and use Ars Magna banish effects from hand to re-search Power Patron engine pieces
• After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan (Inferred)

Why it scores here

Scored as a system, not an average of card scores. The deck reliably opens a searcher engine: about 0.90 odds of at least one of the 20 searcher-text cards in a five-card opening hand, and about 0.95 for the Ars Magna / Elfnote / Power Patron core (Inferred from the hypergeometric table). Its interaction density is high, with 15 hand traps and 13 negation-text cards, and that drives the endboard and going-second scores. However, the list is illegal: 6 distinct cards exceed their copy limits and 3 of them (Elfnote Tinia, F.A. Dawn Dragster, Crystal Wing Synchro Dragon) are Forbidden. Under the rubric this caps the evaluation at a theoretical, structural-only read. No recorded boards, no tournament data and no side deck exist, so the conversion ceiling and median are text-only inference. Popularity in the archetype usage stats was not credited as strength.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Stun secondary; hand-trap-heavy lists are scored as Combo with an interaction read in D7. Structural ≈ 52, Going First ≈ 52, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-12); illegal_list_cap (0). Final formula: Illegal list: theoretical/structural-only. Uncapped 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6; banlist modifier -12 gives 37.6; Illegal cap applied, final = 30. Meta Power null (Provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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 gives about 0.90 odds of a searcher in the opening five cards
• Dense hand-trap and negation coverage (15 hand traps, 13 negation-text cards)
• Full 15-card Extra Deck with several high-ATK bosses

Weaknesses

• Illegal list: 6 cards over copy limit and 3 Forbidden cards
• No Side Deck, so no post-side plan
• Low exact-name purity; many off-archetype copies make the engine less coherent
• No recorded combos, so conversion and median cannot be measured

Critical choke points

• Ash Blossom, Effect Veiler and Ghost Ogre form the only going-second defence; if they are not drawn the engine has no answer
• Forbidden Extra Deck cards (Crystal Wing, F.A. Dawn Dragster) must be removed before the list can be played at all

Recommended changes

Evidence & confidence

• Verified: Illegal status: 6 copy-limit violations, 3 Forbidden cards (legality); Main 57, Extra 15, Side 0 (composition); Card text and stats for the 33 distinct main cards and 15 Extra cards (cards); Usage stats: core 15 of 25 present (usage_statistics)
• Inferred: Opening-hand consistency: P(searcher) ~0.90, P(archetype core) ~0.95 (probabilities); Going-second hand-trap read ~0.86 (probabilities); Interaction density and endboard read from text (D7); Conversion ceiling and median from text only (D3, D4)
• Provisional: Meta Power (null); Matchup fit (D13)
• Data gaps: No combos supplied: conversion ceiling, median and floor are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry; brick and starter rates are Inferred Meta Power Provisional without a dated metagame sample No Side Deck, so post-side is not evaluable
