Ars Magna Deck #766053 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Synchro boards (Mediclius, Elfnote June Pride, Elfnote Seraphim Strelitzia, Infernal Strike Fighter) that push damage through Ars Magna and Elfnote boss monsters; no single reliable finisher; Power Patron Link Monsters and Vidolium (5000 ATK Pendulum) when a Power Patron starter is live
• Turn 1 (going first): Turn 1 starter from the Elfnote, Power Patron or Ars Magna lines (search or Special Summon), then build a Synchro or Link board; hand traps are held for the opponent's first activation
• Turn 2 (going second): Open with hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Droll and Lock Bird) to slow the opponent's first combo, then rebuild from the remaining hand and GY
• Recovery: Ars Magna and Theorealize banish-from-hand or GY effects re-add searchers and recover Synchro or Link bosses from the GY
• After siding: No side deck is run, so no post-side plan exists; the deck has nothing to change between games in a best-of-3

Why it scores here

The deck is scored on its system, not by averaging card scores. Its exact-name Ars Magna purity is only 7 percent: 66 of 71 main copies belong to other sub-archetypes (Elfnote, PSY-Frame, Power Patron, Cyclone, Mulcharmy, Medius and others), so the engines overlap more than they cohere. Its hypergeometric starter odds are modest (P(at least one 3-copy card in a 5-card opening hand) is about 0.25, and the archetype core group reaches about 0.89 in hand), which holds D1 and D2 back. The deck carries 15 hand traps and 13 negation-text cards, which gives it real interaction density and earns D7 and going-second credit, but there are no recorded boards, so the combo ceiling and median are text-only inference and cannot be confirmed. It has no side deck and two copy-limit violations, so it cannot receive a normal Final Contextual score. The result is capped low and labelled theoretical and structural-only. Popularity and archetype usage did not earn points; the usage data confirms the core is present in only 56 percent of the archetype's standard list.

Dimension scores

How the score was computed

Strategy profile: Primary Toolbox; secondary Midrange used only as a reading aid for the interaction-heavy board plan, with no weight change. Structural ≈ 40, Going First ≈ 35, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violations (-9). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*40 + 0.20*35 - 9 = 30; Illegal, so theoretical and structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · key two-card combo ≈ — · full-brick estimate ≈ 0.11 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Large hand-trap and negation suite (15 hand traps, 13 negation-text cards) gives real interaction density
• Archetype core cards are heavily present (Ash Blossom, Mulcharmy Fuwalos, Ars Magna Corruption and Division are all in the core)
• Two-way Extra Deck coverage with Link, Synchro, Xyz and Fusion options

Weaknesses

• Exact-archetype purity is only 7 percent, so the engine is spread over several sub-archetypes
• Two copy-limit violations (Elfnote Lucina at 3 copies vs 1; Ash Blossom at 3 vs 2)
• No side deck, so no post-side plan
• Starter odds are modest and the brick risk is high

Critical choke points

• Single starter draws in a 5-card opening hand are about 0.25 odds per 3-copy card
• Relies on hand traps to protect the first board, which fail when the opponent has no activation
• No recorded boards confirm that the first combo line completes

Recommended changes
