Ars Magna Deck #773471 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox, Tempo
• 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: Extra Deck boss monsters from the Phantasm and Power Patron/Ars Magna engines (for example Chaotic Phantasmal Sacred Beasts, Infinity of the Sacred Beasts - Raviel, Gustav Rocket, Hope Harbinger) (Inferred from card text); Link and Fusion pressure through Mediclius, Accesscode Talker and Artmage Diactorus (Inferred from card text; no recorded boards)
• Turn 1 (going first): Search a Sacred Beast starter (Thunderclap, Martyr, Calamity, Released) and keep Ash Blossom up as the interaction layer (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird) to slow the opponent, then Phantasm or Power Patron summons from the Extra Deck (Inferred)
• Recovery: Card of the Soul, Tokusano Shinkyojin and Fallen Paradise draw and reload; GY effects of Sacred Beasts Released and Thunderclap recur starters (Inferred from text)
• After siding: None: the deck has no Side Deck, so there is no best-of-3 adaptation plan

Why it scores here

This list is Illegal: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2, and the Extra Deck holds 20 cards against a maximum of 15. Under the rubric it is therefore capped and scored as structural-only, so the 30 is a cap, not a normal Final Contextual score. The structural read (58) comes from the system: a Sacred Beast starter package with about 0.98 odds of at least one searcher in the opening hand (Inferred), redundant hand traps and draw effects, and a 5000/4000 ATK Extra Deck top end. The deck is split across Phantasm, Ars Magna, Power Patron and Medius sub-archetypes (exact-name purity 9.6%), which costs engine coherence, and it has no Side Deck. Popularity did not earn points: the archetype core is only 32% present, and no combo boards or tournament data exist. Card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-4); engine_conflicts (-4). Final formula: Illegal cap applied: normal formula 0.80*Structural(58) + 0.20*TournamentReliability(50) + Modifiers(-8) = 48 is NOT published; theoretical structural-only score capped at 30 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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 and draw text gives high odds of a live starter
• Layered hand traps and negation (Ash Blossom, Ghost Ogre, Droll, Chaotic Phantasmal, Gallant Bandit)
• High ATK closers (Chaotic Phantasmal 5000, Gustav Rocket 5000, Raviel 4000)

Weaknesses

• Illegal list: Ash Blossom 3 copies vs limit 2; Extra Deck 20 vs maximum 15
• Engine split across Phantasm, Ars Magna, Power Patron and Medius (exact-name purity 9.6%)
• No Side Deck, so no post-side plan
• No recorded boards, so the combo floor and median are unknown

Critical choke points

• Extra Deck over the size cap: 5 Extra cards must be cut before the list is legal
• Single Ash Blossom copy count over limit also weakens the hand-trap package on going second

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom 3 copies vs legal 2; Extra Deck 20 vs maximum 15; Side Deck 0; Card text and stats for all 53 main and 20 extra cards; Hypergeometric draw probabilities from the resolved list; Archetype purity 9.6% from archetype_spread
• Inferred: Starter access and consistency (D1, D2) from hypergeometric odds and text; Interaction density and resilience from negation and hand-trap text; Going-first and going-second plans from card text
• Provisional: Meta Power (null); Matchup and format fit (D13); Median output (D4)
• 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/starter rates) Meta Power is provisional without a dated metagame sample Deck title is null
