Ars Magna Deck #770489 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 34/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Ars Magna / Power Patron link loop converting Link-Summon and banish-from-hand searches into ATK-tripled and multi-attack boards (Inferred from text; no combo boards recorded); Light and Darkness Ritual Black Chaos / Magician of Dark Chaos boards (3000 / 2800 ATK) via Ritual searches
• Turn 1 (going first): Open a Mulcharmy draw/hand-trap engine plus one Ars Magna or Power Patron starter; search a Theorealize or Ars Magna Spell/Trap (Inferred)
• Turn 2 (going second): Use the 14 hand traps (Ash Blossom, Ghost Ogre, Infinite Impermanence, Nibiru, Droll & Lock Bird) to disrupt the opponent's first board, then Link out (Inferred)
• Recovery: Mulcharmy draw effects and Ars Magna banish-from-hand searches rebuild a hand after one interruption (Inferred)
• After siding: Not assessable: the deck runs no Side Deck (side_count 0)

Why it scores here

The deck scores as a system, not as an average of its cards. It has strong interaction density: 14 hand traps and 9 negation-text cards give it a broad going-second disruption layer. Its engines are split across at least five sub-archetypes (Ars Magna and Power Patron, Mulcharmy, Light and Darkness Ritual, Medius/Theorealize, Artmage), and only 5 of 74 copies are exact-name Ars Magna, so the starter-to-engine conversion is fragile. Consistency is low: the core group has about 83% chance of one copy in a 5-card hand, but many cards are generic or off-plan, and no combo boards were recorded, so median output is unknown. The list is also illegal: five Forbidden cards and two over-limit Limited/Semi-Limited cards, plus no Side Deck. That caps the score at a theoretical, structural-only read. Popularity and archetype usage were not credited, and card power scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12). Final formula: Illegal deck: theoretical/structural-only. 0.80*Structural(49) + 0.20*TournamentReliability(35) = 46, then banlist-exposure modifier -12 = 34 (capped low, not a normal Final score).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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

• Heavy going-second disruption: 14 hand traps and 9 negation-text cards
• Recursive draw and search from Mulcharmy and Ars Magna banish-from-hand effects
• Multiple top-end boards (Black Chaos 3000, Magician of Dark Chaos 2800) through Ritual Summon

Weaknesses

• Illegal list: five Forbidden cards and over-limit Limited/Semi-Limited cards
• Engine split across 5+ sub-archetypes; exact Ars Magna purity 6.8%
• No Side Deck
• Core usage cards Purification Power Patron (100% inclusion elsewhere) and Mediclius (96%) are absent

Critical choke points

• Single exact-name Ars Magna or Power Patron starter in hand
• Forbidden Called by the Grave and Triple Tactics Talent are illegal, so any line depending on them does not exist in-format

Recommended changes

Evidence & confidence

• Verified: Legality: 59 main / 15 extra / 0 side; 7 copy-limit violations; 5 Forbidden cards present; Card text and archetype tags from resolved evidence; Copy histogram and type spread
• Observed: Archetype usage stats: core cards Purification Power Patron and Mediclius are absent from this list
• Inferred: Starter probability 0.237 (3-copy) and 0.83 core-group open rate from hypergeometric estimates; Hand-trap and negation density as interaction quality; Going-first and going-second plans from text
• Provisional: Meta Power (null) and matchup/format fit (no dated metagame sample); Post-side plan (no Side Deck)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample No Side Deck (side_count 0) No guides attached (guides_evidence total 0)
