Ars Magna Deck #766099 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Power Patron Link Monsters and Synchro/Link beaters (Vidolium 5000 ATK, Junora 3100 ATK, Mediclius 3000 ATK) backed by Ars Magna and Elfnote disruption; no recorded boards to confirm the line; Elfnote Synchro pressure (Elfnote June Pride, Elfnote Seraphim Strelitzia) and Medius/Theorealize recursion
• Turn 1 (going first): Open a starter from Elfnote, Power Patron or Mulcharmy draw bodies, search with Ars Magna or Theorealize, and hold Ash Blossom, Nibiru, Effect Veiler and Ghost Ogre for the opponent's first Main Phase
• Turn 2 (going second): Stop the opponent's first board with hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Droll & Lock Bird, Nibiru) and rebuild through Medius, Theorealize Past Lull and Ars Magna banish effects
• Recovery: Recover from a single hand-trap or Ash Blossom response by reusing GY-based Medius and Theorealize Past Lull Special Summons and Mulcharmy draw effects
• After siding: Not available: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens a starter: the archetype-core proxy gives about 0.93 chance of at least one core card in a 5-card opening hand, and 19 searcher-text cards add redundancy (Inferred). Its interaction is the strongest part of the list, with 14 hand traps and 10 negation-text cards covering Ash Blossom, Effect Veiler, Ghost Ogre, Droll and Nibiru, which lifts the going-second plan. Conversion is the weak point: there are no recorded boards, and the 70 cards are 65 off-archetype copies spread across Elfnote, Mulcharmy, Power Patron, Artmage, Medius, Pendulum and Greed, so the engines compete for the same hand. The score came from consistency, interaction and the ceiling of the Extra Deck on the system, not from Ars Magna's popularity and not from averaging the card scores. The list is Illegal (Ash Blossom 3 vs 2, Elfnote Lucina 2 vs 1), so the score is capped and is structural-only.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary with Stun secondary for the hand-trap base; Structural weights taken from the Toolbox row. Structural ≈ 56, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-6); no side deck (-2). Final formula: Illegal: uncapped Final = 0.80*56 + 0.20*40 + (-18 modifiers) = 34.8, capped to 30 as theoretical/structural-only; Meta Power provisional (null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Hand-trap density (14) plus negation text gives strong going-second interaction
• Archetype-core redundancy with about 0.93 chance of a starter in a 5-card hand
• Extra Deck has high-ceiling beaters (Vidolium 5000 ATK, Junora, Mediclius) and flexible Synchro coverage

Weaknesses

• Illegal as built: Ash Blossom and Elfnote Lucina exceed their copy limits
• Fragmented engine: 65 of 70 archetype copies are off-archetype across six sub-archetypes
• No Side Deck, so there is no post-side plan
• High brick and dead-hand risk from hand traps and Mulcharmy's no-cards condition

Critical choke points

• A single Power Patron Link Monster is needed for most Ars Magna and Power Patron payoffs
• Ash Blossom and Effect Veiler carry the going-second plan; if both are dead the hand has no answer to a first-turn board
• Legal-copy cuts (Ash Blossom and Elfnote Lucina) remove redundancy from the hands that need it most

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal; Ash Blossom 3 copies over the 2 legal, Elfnote Lucina 2 over the 1 legal; Main count 55 and Extra count 15 are within the TCG size rules; Side count 0; Archetype purity 7.1%; 65 of 70 archetype copies off-archetype; Extra Deck breakdown: 9 Synchro, 4 Link, 1 Xyz, 1 Fusion
• Observed: Usage statistics show Ars Magna core cards at 100% inclusion
• Inferred: Archetype-core proxy gives about 0.93 chance of at least one core card in a 5-card hand; Hand-trap density gives strong going-second interaction; Engine conflicts across six sub-archetypes reduce consistency; Dead-hand risk from hand traps and the Mulcharmy condition
• Provisional: Meta Power is null because no dated metagame sample was supplied; Matchup fit (D13) is provisional with no tournament link
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional unless a dated metagame sample is supplied Data inconsistency: usage_statistics marks Purification Power Patron, Mediclius, Galaxy-Eyes and other Extra Deck cards as in_this_deck false, but the cards list shows them in the Extra zone No side deck was supplied (side_count 0)
