Ars Magna Deck #770635 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

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

Legality

Main 53 / Extra 20 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Phantasm boss Special Summons (The Chaotic Phantasmal Sacred Beasts 5000 ATK, Superdreadnought Rail Cannon Gustav Rocket 5000 ATK, Infinity of the Sacred Beasts 4000 ATK, Calamity of the Sacred Beasts 4000 ATK), with Power Patron Link monsters as a secondary pressure route.; Link and Xyz pressure through Power Patron and Train monsters, plus Gustav Max direct damage (Inferred).
• Turn 1 (going first): Search Sacred Beast Level 10 monsters with Sacred Beasts Thunderclap, Sacred Beasts Released and Card of the Soul, then Special Summon a Phantasm boss (Inferred; no recorded boards).
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Nibiru, The Great Gallant Bandit) to break the opponent's starter, then land a Phantasm boss from the Extra Deck (Inferred).
• Recovery: Recur Sacred Beasts from the GY with Sacred Beasts Released, Martyr of the Sacred Beasts and Theorealized Medius, and rebuild with Card of the Soul (Inferred).
• After siding: None. The list runs no Side Deck (0 of 15), so there is no post-side plan.

Why it scores here

The deck opens reliably: 27 searcher-text cards give a 0.977 chance of at least one searcher in a going-first 5-card hand, and the 11-copy Ars Magna/Sacred Beast core gives about 0.70 odds of at least one core card (Inferred). Its ceiling comes from the Phantasm boss pool, but the list splits across three engines (Phantasm Sacred Beasts, Power Patron/Ars Magna and Train) with only 9.6% exact-name Ars Magna purity, so the median output is likely well below the ceiling (Inferred). Eight hand traps and eight negation-text cards give it going-second and mid-combo interaction. The score is capped because the deck is illegal (Ash Blossom at 3 copies against a limit of 2; Extra Deck at 20 against a maximum of 15), it has no Side Deck, and no recorded boards exist. Popularity and archetype label did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52.3, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Copy-limit violation (-5); Extra Deck over size cap (-4); No Side Deck (-3). Final formula: Structural 52.3 (Combo profile); 0.80*52.3 + 0.20*45 = 50.8; modifiers -12 give 38.8; Illegal-deck cap applied, final 30 (theoretical/structural only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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 searcher text (27 cards) gives high odds of finding a starter in the opening hand
• Layered hand traps and negation text provide going-second interaction
• Phantasm boss pool has high ATK (4000-5000) for closing

Weaknesses

• Illegal as submitted: copy-limit and Extra Deck size violations
• Three engines (Phantasm, Power Patron/Ars Magna, Train) compete for the same resources
• No Side Deck
• Only 9.6% exact-name Ars Magna purity, so the archetype label overstates coherence

Critical choke points

• Summoning Phantasm bosses requires Sacred Beast Level 10 monsters in hand, so a hand without them stalls the engine (Inferred)
• Ash Blossom at 3 copies is illegal, and a legal list would have to cut one copy

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal (Ash Blossom 3 of 2; Extra Deck 20 of 15); Limited-list copies within legal limits (Droll, Linkuriboh, Terminus, S:P Little Knight, Gustav Max at 1); Composition: 53 main, 28 distinct; 20 extra (7 fusion, 9 link, 4 xyz); 0 side; archetype purity 9.6%; Card text and stats from the evidence excerpts
• Inferred: Opening-hand odds from hypergeometric estimates (0.977 searcher, 0.70 core, 0.645 hand trap); Engine coherence and conflict across Phantasm, Power Patron and Train; Going-first and going-second plans from card text; Interaction and resilience from negation and hand-trap text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• 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, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck: post-side performance cannot be assessed Deck is illegal as submitted, so the score is a theoretical cap, not a normal evaluation
